Seizures can be upsetting to watch but are usually over quickly. A pet that has had a seizure for the first time should see a veterinarian. Seizures that last longer than 5 minutes or that happen in clusters (2 or more seizures in a day) are medical emergencies.
What Is a Seizure?
Seizures are involuntary movements caused by abnormal electrical activity in the brain. How a seizure looks depends on the type of seizure.
Is It a Seizure?
Some other conditions can look like seizures. Heart disease can cause fainting spells that look very similar to seizures. Other nervous system disorders, orthopedic problems, pain responses, trembling, and even extreme itching can mimic seizures.
If your pet has an episode of unusual movement or behavior, you don’t have to decide whether it was a seizure. Take your pet to a veterinarian and be prepared to describe the episode in as much detail as possible. A video can be very helpful. The veterinarian will ask how long the episode lasted, what your pet did (paddling the legs, urinating, etc), and whether your pet had access to toxins or medications before the episode. Your veterinarian will also need to know if your pet has had seizures before and if so, your pet’s age at the first seizure.
A true seizure is followed by a period of disorientation or other unusual behavior. Watch for this phase and tell your veterinarian if you see it. True seizures also begin with an aura phase (nervousness, seeking attention), but pet owners don’t often witness this phase.
Causes of Seizures
The many possible causes of seizures can be classified as things outside the brain (problems elsewhere in the body that affect brain function), things inside the brain (structural problems with the brain itself), or epilepsy.
Primary epilepsy is the most common diagnosis in dogs that start having seizures between the ages of about 6 months and 6 years. It is genetic in some breeds but can happen in dogs of any breed. Primary epilepsy is uncommon in cats. Dogs with primary epilepsy seem normal between seizures. Not being normal between seizures could be a sign that the seizure is caused by something else.
Veterinarians perform diagnostic tests to look for the cause of the seizure and rule out other conditions that mimic seizures. Primary epilepsy is diagnosed by not finding another cause for the seizure. Your veterinarian might recommend referring your pet to a veterinary neurologist.
What to Do if Your Pet Has a Seizure
Treatment depends on the cause of the seizure. Dogs with epilepsy generally have repeat seizures, and the choice of medication depends on the frequency and severity of the seizures. Epilepsy is a lifelong condition that can be managed but can’t be cured, so dogs with epilepsy usually need medication for life. Whatever the cause of the seizure, work in partnership with your veterinarian to develop your pet’s treatment plan. Anticonvulsant medication has specific dosage requirements, so don’t change the dose or timing of your pet’s medication without consulting your veterinarian.

Fleas don’t just cause itching. They also carry infectious diseases that can be contagious to people. Controlling fleas on your pets protects your whole family’s health.
Tapeworms are parasites that live in the intestines. They shed small body segments called proglottids that pass out of the host animal’s body in the feces. Tapeworm segments in the stool look like whitish rice grains.
Fleas transmit a type of tapeworm that commonly infects dogs and cats. Dogs and cats become infected by swallowing a flea. Tapeworms rarely cause significant disease in dogs and cats.
The dog and cat tapeworm that is carried by fleas, Dipylidium caninum, can also infect humans (usually children) who swallow a flea.
Bartonellosis (Cat Scratch Disease)
Bartonella species are bacteria that cause a variety of diseases in humans and other animals. Cat scratch disease and endocarditis (heart valve infection) are just 2 of the serious illnesses caused by Bartonella infection.
Fleas are the most common insect vector for Bartonella henselae, the species that causes cat scratch disease. Fleas can also carry other Bartonella species. Infected cats and dogs might or might not have any symptoms of infection.
Bartonellosis is a human health risk. Treating your cat with a cat-safe flea preventive reduces the risk of cat scratch disease for people in contact with your cat.
Rickettsiae are a group of bacteria responsible for diseases such as typhus and Rocky Mountain spotted fever. Rickettsiae are spread by arthropods, including fleas and ticks. The types of fleas that infest dogs and cats transmit Rickettsia typhi (which causes murine typhus) and Rickettsia felis. Both of these bacteria can also cause disease in people.[1,4]
Plague, including bubonic plague and the Black Death, is caused by infection with the bacterium Yersinia pestis. The Oriental rat flea (Xenopsylla cheopis) transmits the bacterium usually to rodents but sometimes to cats, dogs, other animals, and humans. Rat fleas in the western United States and other parts of the world still harbor Yersinia.
Cats infected with certain types of Mycoplasma bacteria develop anemia (low red blood cell count). Fleas are thought to be a source of infection for cats.
Fleas cause skin disease in animals that scratch or chew themselves to relieve the itch. Just a few fleas can set off intense itching in an animal with a flea allergy.
Because fleas feed on blood, animals with lots of fleas can develop anemia from blood loss. This anemia can be life threatening.

We all know that cats sometimes throw up hairballs. But hairballs aren’t the only reason cats vomit. Don’t assume that vomiting is normal for your cat, even if it’s been going on for months or years.
Consult your veterinarian if your cat has any of these symptoms:
Hairballs (trichobezoars in medical speak) are wads of hair in the digestive tract. Cats swallow loose hair when they lick their fur. Hair usually passes through the digestive tract without causing any problem. But sometimes hair packs together into a mass in the stomach or intestine.
A hairball is usually shaped like a cylinder. If you see one on your favorite rug, you might mistake it at first for feces. Hairballs are often about the same size and shape as a log of cat poop. But if you look at a hairball closely you’ll see that it’s made of tightly packed hair (and it doesn’t smell like poop).
We don’t really know how often cats normally vomit up hairballs. In an informal poll at a cat clinic in England, cat owners reported that nearly three-fourths of their cats had never vomited up a hairball. About 1 in 6 cats expelled a hairball once a year, and 1 in 10 cats expelled a hairball at least twice a year. Owners reported that long-haired cats brought up hairballs more frequently than short-haired cats did.
Hairballs that aren’t vomited up or passed in the stool can block the digestive tract. Symptoms include vomiting, decreased appetite, and signs of belly discomfort (which can be easy to miss in cats). Cats with intestinal blockages may need surgery.
Causes of Hairballs
Healthy cats occasionally bring up hairballs just because they’re cats and they groom themselves. But sometimes hairballs are a sign of another problem. Cats are more likely to have problems with hairballs if they swallow excessive amounts of hair or have a disorder that slows the movement of material through the digestive tract.
Fleas and itchy skin conditions can lead to excessive grooming. Cats also overgroom in response to pain or stress. More grooming means more hair swallowed and an increased chance of hairballs.
The symptoms of digestive tract diseases like inflammatory bowel disease and intestinal lymphoma (a type of cancer) can be mistaken for hairballs. In one study, some cats with hairballs blocking the intestines also had serious intestinal disease. These diseases affect the way food and hair move through the digestive tract and may put cats at higher risk of hairballs. Hairballs can also irritate the digestive tract, causing inflammation.
Ask your veterinarian before treating your cat’s vomiting or hacking with over-the-counter remedies or hairball diets. Hairballs might not be responsible for the symptoms.
Brushing the coat to remove loose hair is safe and might be all that’s needed to reduce hairballs in healthy cats. Long-haired cats that regularly bring up hairballs may benefit from having their fur trimmed.
If you’re noticing more hairballs than usual, ask your veterinarian to check your cat for underlying problems. If the symptoms point to an intestinal disease, your cat might need a series of diagnostic tests (such as bloodwork, ultrasound, and possibly a biopsy of the intestines).

Adult heartworms grow up to a foot long, block blood flow around the heart, and cause inflammation within blood vessels. The damage continues as long as the heartworms remain in the body.
Heartworm treatment protocols for dogs are designed to remove the worms while reducing the risk of treatment complications. No safe heartworm treatment exists for cats and ferrets. Your veterinarian can recommend appropriate heartworm preventives for your dog, cat, or ferret.
Heartworm infection is diagnosed with a blood test. Your veterinarian might confirm the diagnosis with another test before proceeding with treatment.
Other tests, like x-ray imaging, echocardiography (heart ultrasound), and other blood tests, are used to assess the extent of damage. The results can affect the treatment plan, so your veterinarian might recommend these tests even if your dog isn’t showing any symptoms of infection. Dogs with blood clotting problems or signs of heart disease need a full diagnostic workup before treatment starts.
Any activity that increases the heart rate and blood pressure can worsen the problems caused by heartworms. Dogs with heartworms need to stay as quiet as possible to limit the damage. Once treatment begins, pieces of dead worms can break off and lodge in small blood vessels, potentially causing serious problems and even death. Strict exercise restriction is the best way to reduce the risk.
The American Heartworm Society (AHS) recommends restricting activity from the time heartworms are diagnosed until 6 to 8 weeks after the last dose of heartworm treatment. Dogs should ideally stay indoors in a small area where they can’t run or jump. Some dogs need to be confined to a crate. They should go outdoors on a leash only long enough to pee and poop. Ask your veterinarian about the level of confinement your dog needs.
Before Killing the Heartworms
Before dogs begin receiving adulticide (medication that kills adult heartworms), they may need treatment for heartworm-related problems. They should receive a certain type of heartworm preventive to remove larvae, or immature worms, from the bloodstream. They also benefit from a monthlong course of doxycycline, an antibiotic, to eliminate a bacterium that lives inside heartworm cells. This bacterium is partly responsible for the inflammation that occurs when heartworms die.
The AHS recommends that dogs start adulticide treatment 2 months after receiving a heartworm diagnosis (30 days after the last dose of doxycycline). Dogs should have limited activity during these 2 months.
The only adulticide currently approved for use in the United States is melarsomine. This drug is given by injection in a veterinary hospital. Your dog may need to stay in the hospital for observation after a melarsomine injection.
The number and timing of injections may vary depending on the situation. The current AHS recommendation is to give a series of 3 injections: 1 injection followed by a 30-day wait, then 2 injections given 24 hours apart. Your veterinarian will suggest a protocol that’s appropriate for your own dog.
Complete exercise restriction is crucial during adulticide treatment and for several weeks after the last dose. Your veterinarian may also prescribe medications to reduce adverse effects of treatment.
Your dog can be retested for heartworms several months after the last melarsomine injection. The goal of treatment is to remove all stages of heartworms.
Protocols to manage heartworm infection without using melarsomine are sometimes called “slow-kill” treatments. These protocols consist of giving doxycycline for a month and beginning a specific type of heartworm preventive to remove larvae. Heartworms take from several months to a year or more to die with these protocols.
The disadvantage of slow-kill treatment is that it allows adult heartworms to remain in the body for much longer than with adulticide treatment. The worms continue to damage the heart and blood vessels during this time. For this reason, the AHS does not recommend this method as standard treatment. Dogs receiving slow-kill treatment should also have exercise restriction for as long as adult heartworms remain in the body.
The advantage of slow-kill treatment is that it costs much less than melarsomine. Slow-kill methods have been proposed for dogs that would otherwise go untreated or be euthanized, like those in shelters or in areas where melarsomine is not available. Slow-kill treatment also offers an option for dogs at high risk of complications from adulticide treatment.

Hypertension (high blood pressure) is fairly common in older cats. The condition can cause serious health problems but is treatable. Senior cats and cats with kidney or thyroid disease benefit from routine blood pressure screening.
High blood pressure is silent; it has no symptoms of its own. But high blood pressure damages organs of the body, causing symptoms that cat owners might notice.
In cats, hypertension is usually caused by another disorder. The most common causes in cats are chronic kidney disease and hyperthyroidism (overactive thyroid). Sometimes high blood pressure in cats seems to develop on its own with no known cause, as can happen in humans. Older cats are more likely than younger cats to have hypertension.
Blood pressure measurement
Current guidelines recommend measuring blood pressure in cats in these categories [2,4]:
In cats, blood pressure is usually measured with an inflatable cuff similar to the cuffs used in people (but much smaller!). The cuff is placed around a leg or the tail. During the procedure cats can lie down or sit upright, whichever is more comfortable for them. Most operators try to position the cuff at the level of the heart, but forcing a cat to lie down can cause agitation and raise the blood pressure.
Blood pressure readings are most accurate in calm cats. You might be asked to wait with your cat in the examination room for a few minutes to give her time to settle down and get comfortable. Consider bringing a cat bed, blanket, or towel from home so your cat can rest on something familiar during the procedure. Blood pressure is typically measured several times during each session to account for variation from motion or anxiety. Cats tend to tolerate the procedure well.
A systolic blood pressure below 140 mm Hg is considered normal in cats. (In blood pressure readings like “110/70 mm Hg,” systolic pressure is the first number and diastolic pressure is the second number). A systolic blood pressure of 160 mm Hg or higher indicates hypertension and an increased risk of organ damage.
Veterinarians often measure blood pressure on more than 1 clinic visit before making a definite diagnosis of hypertension. Cats’ blood pressures can vary from visit to visit depending on their stress levels. However, signs of organ damage can confirm the diagnosis and justify starting treatment after only 1 measurement session. Cats with hypertension (or at risk for hypertension) should have blood pressure checks every few months.
The goal of treatment is to reduce the risk and extent of organ damage. The underlying problem causing the high blood pressure is treated at the same time. Most cats with hypertension receive daily oral medication. The dose is adjusted as needed after blood pressure rechecks. Medication is usually effective in reducing the blood pressure, especially if the underlying disease is also controlled.

Chronic kidney disease is common in cats. It can affect cats at any age but is most common in older cats. The disease has no cure. The goals of treatment are to slow the progression of the disease and maintain a good quality of life for the cat.
Functions of the Kidneys
The kidneys filter the blood and excrete waste products into the urine. When the kidneys don’t work properly, these waste products accumulate in the body. The kidneys balance the body’s water level by adjusting the urine concentration. Kidney disease impairs the ability to concentrate the urine and retain water in the body, so animals with kidney disease become dehydrated. The kidneys also help regulate blood pressure, red blood cell production, and acid-base balance.
Signs of Kidney Disease
Kidney disease is already advanced (at least two-thirds of kidney function lost) by the time signs of illness appear. Cats typically have the following signs:
Keep an eye on the size of the urine clumps in your cat’s litter box. Enlarging urine clumps can mean that urine volume is increasing, which is one of the earliest signs of kidney disease. Other disorders (like diabetes) can also increase the urine volume, so larger-than-usual urine clumps warrant a visit to the veterinarian.
As chronic kidney disease progresses, the loss of kidney function leads to further problems:
Causes of Kidney Disease
Acute kidney injury is a rapid loss of kidney function over hours to days. Some of the many possible causes are toxins, infections, and shock. Depending on the cause and severity, acute kidney damage can sometimes be reversed with treatment.
Chronic kidney disease is more common than acute kidney injury in cats. In chronic kidney disease, kidney function gradually decreases over time. The cause is usually not known. The same entities that cause acute kidney injury can lead to chronic kidney failure. Other possible causes are high blood pressure, abnormal kidney development, infection or inflammation of the kidneys, disorders that alter blood flow to the kidneys, and cancer.
Tests are used to diagnose kidney disease, assess the stage of the disease, identify metabolic problems caused by the disease, diagnose other disorders (like thyroid disease) that cats with kidney disease sometimes also have, and possibly reveal the cause of the kidney problem.
Blood tests and urinalysis (analysis of urine) are typically the first diagnostic tests for cats with suspected kidney disease. Blood pressure measurement, urine culture to test for bacterial infection, and ultrasound or x-ray imaging of the urinary tract are also commonly performed for cats with kidney disorders.
Cats with chronic kidney disease benefit from regular testing to monitor disease progression and adjust treatment. In general, these cats should see a veterinarian for blood tests, urinalysis, and blood pressure measurement every 3 to 6 months.
The stage and substage of chronic kidney disease are evaluated with specific tests:
Chronic kidney disease can’t be cured, but it can be managed. The prognosis is variable; some cats can live with the disease for years. If your cat has kidney disease, work with your veterinarian to craft a treatment plan that will give your cat a good quality of life.
Treatment strategies are based on the stage of disease and the individual cat’s needs and may include the following[1,4]:

Tooth root abscesses are painful and need prompt treatment, but the signs can be easy to miss. Dogs don’t always show that their mouths hurt, and tooth abscesses can mimic other conditions.
Tooth root abscesses are pockets of pus caused by bacteria that invade the deep structures of the tooth. They often occur in teeth with severe periodontal disease or gingivitis (gum disease), especially if the gum has receded around the tooth.
Teeth that are cracked or fractured are also at risk for root abscesses. Teeth can fracture when a dog chews on something hard, like a bone, cow hoof, ice cube, hard nylon toy, or rock. Fractures that expose the pulp cavity (the inner part of the tooth) give bacteria a route to the tooth root.
The upper fourth premolar—the large cheek tooth on each side of the upper jaw—is a common site of root abscess. This tooth, also called the carnassial tooth, is used to crush food. When a dog crunches something hard, a carnassial tooth can sustain a slab fracture (shearing off a slab from the side of the tooth) or can crack down the center. The roots of the carnassial tooth reach nearly to the eye, so an abscessed root causes swelling just below the eye.
Root abscesses can occur in any tooth. The large canine (fang) teeth are frequently broken and are also common sites of root abscesses.
Although tooth root abscesses are very painful, dogs’ signs of mouth pain can be subtle. Some dogs don’t show any symptoms at all. Signs of a tooth root abscess can include the following:
A veterinarian may be able to find evidence of a tooth root abscess during examination of an awake patient. However, dogs with tooth root abscesses sometimes have too much mouth pain to allow much of an oral examination without sedation.
Diagnosis often requires dental radiographs (x-ray images) or at least a full oral examination with the patient under anesthesia. Dental radiographs sometimes reveal tooth root abscesses that can’t be seen any other way.
Untreated tooth root abscesses cause prolonged pain and tooth loss. The infection can spread to other tooth roots and to the face, potentially even affecting the eye.
Dogs with tooth root abscesses need antibiotics and pain relief. The source of the infection must also be removed. There are 2 options for treating an abscessed tooth root:
If you think your dog might have a tooth root abscess, make an appointment with your veterinarian as soon as possible. Your veterinarian will examine your dog and, if the signs indicate an abscess, will probably prescribe an antibiotic and an analgesic (pain reliever).
The next step will be either another appointment with your veterinarian for tooth extraction or referral to a dental specialist for possible root canal therapy. Both extraction and root canal therapy require general anesthesia.
If you would like your dog to keep his tooth, root canal treatment is the best option. Antibiotics alone are rarely enough to treat a root abscess. However, not all teeth are candidates for root canal therapy. The dental specialist will evaluate dental radiographs to see if root canal treatment is a good option and will extract the tooth if necessary.
Sometimes tooth root abscesses are unavoidable. But you can take some measures to reduce your dog’s risk:

Brachycephalic (flat-faced) dogs and cats are popular, but those cute squashed noses can cause some serious health problems. If you have a brachycephalic pet, watch for breathing trouble (snoring and grunting are not normal). These pets are also prone to heat stress, especially if they’re overweight.
Brachycephalic means “short-headed.” Brachycephalic animals have short noses, round heads, and large, low-set eyes. Examples are English and French bulldogs, pugs, Boston terriers, shih tzus, and Persian cats. If you think these pets are adorable, you're not alone. Studies have shown that many people are attracted to facial features in animals that are similar to those of human infants.
Unlike dog breeds that were developed for tasks like hunting, brachycephalic dogs have been bred over time for looks. Unfortunately, breeding for form over function has compromised the health of many of these dogs.
Earlier this year the British Veterinary Association released a policy position on the welfare of brachycephalic dogs. Their aims are to improve the health of future generations of these dogs and to increase awareness of the problems caused by breeding for extreme brachycephaly. The association highlighted 5 of the most common medical concerns: respiratory, eye, reproductive, skin, and dental problems.
Many brachycephalic animals cannot breathe normally. Although the bones of the face are shortened, the soft tissues are not, leaving excess tissue that can block the airway. Signs of impaired breathing include snoring, snorting, and exercise intolerance. Brachycephalic animals are at risk for heat stroke, respiratory distress, and collapse. Long-term labored breathing can also cause digestive tract problems like gagging and vomiting. Obesity makes all of these problems worse.
Brachycephalic obstructive airway syndrome includes 3 main anatomic abnormalities: narrow nostrils, elongated soft palate (excess tissue at the roof of the mouth), and everted laryngeal saccules (tissue that blocks airflow through the trachea, or windpipe). Some animals require surgery to correct these problems. Brachycephalic animals may also have an abnormally narrow trachea, which gives the effect of constantly breathing through a small straw.
Brachycephalic animals have shallow eye sockets and large eyelid openings, so their eyes are not as well protected as those of other animals. Many also have impaired tear production (dry eye), reducing their defense against eye irritants. Skin folds at the top of the nose may cause hair to rub against the eyes. These problems can cause eye ulcers and eventual blindness.
Some brachycephalic breeds have trouble giving birth naturally because the puppies’ heads are too large to fit through the mother’s pelvis. One study found that over 80% of English bulldog, French bulldog, and Boston terrier litters born in the United Kingdom were delivered by cesarean section.
Skin and dental disease
Folds of loose skin give bacteria and yeast a handy place to grow, so brachycephalic animals are prone to skin fold infections. Because of their shortened upper jaw, they often have crowded or maloccluded teeth.

According to the Association for Pet Obesity Prevention, up to 54% of dogs and 59% of cats in the United States are overweight. That’s more than 40 million dogs and 50 million cats. Is your pet one of them?
Obesity has been linked to arthritis, diabetes, heart disease, immune system disorders, liver disease, and other health problems in pets. In recognition of National Pet Obesity Awareness Day (October 11), here’s how to tell if your pet is overweight.
Body condition scoring
Body condition scoring assigns a number to a pet’s condition to make it easier to track changes over time. Body condition score charts typically use either a 5-point or a 9-point scale. The ideal body condition score is 3 on a 5-point scale or 5 on a 9-point scale. Check out one of these body condition charts to see where your pet falls on the scale:
Always bring your pet in for a physical examination before reducing its calorie intake or starting an exercise program. Some medical problems can cause weight gain. Pets with these conditions might need to go on a diet, but they also need treatment:
Other medical conditions can mimic obesity. A pet with one of these conditions might have a big belly but actually be thin overall, and restricting its food could be harmful:
We’re happy to discuss your pet’s weight with you and suggest a diet and exercise plan for your pet that will work for your family. (Telling you “no table food EVER” is not very helpful if you have a toddler in the food-throwing stage). And remember: your pet’s weight is not a reflection of your own health or of how much you love your pet. If we tell you your pet needs to lose weight, it’s only because we want your pet to live a long life and be as healthy as possible.

With the Fourth of July and frequent thunderstorms, summer can be tough for pets that are afraid of loud noises. Medication and behavior therapy can help, especially when treatment begins early.
Noise phobia is common in dogs. In some behavior studies, up to half of dogs show fear responses to loud noises. Some dogs are afraid of only one type of sound; others are fearful of several. Fireworks, thunder, and gunshots are common triggers. Vacuum cleaners, construction noise, sirens, and other sounds can also set off fear reactions. Dogs with noise phobia may also have other anxiety disorders like separation anxiety.
Some behavior specialists classify storm phobia separately from noise phobia because affected dogs may be sensitive to environmental factors (like changes in barometric pressure) in addition to noise. Storm-phobic dogs often start acting anxious long before the storm arrives.
Noise phobia gets worse with time if not treated. Owners sometimes don't seek treatment until a dog's symptoms become severe, but phobias are usually easier to manage while the symptoms are still mild.
Signs of noise phobia
Being startled by a sudden loud noise is normal. Dogs with noise phobia develop irrational, ongoing fear responses to noise triggers. They can hurt themselves and damage property. Panicking pets may also hide or freeze, which is less obvious than breaking through a window but is still a sign of fear. Pets with noise phobia can have various reactions:
Most behavior specialists suggest treating phobias with environmental modification and behavior therapy, usually combined with medication. However, treatment is tailored to each pet's needs. Before starting treatment, your pet may need diagnostic tests to rule out medical problems that can contribute to anxiety.
Environmental modification and behavior therapy
Pets should have a safe place to escape the noise. This can be a windowless interior room, a closet, a bathroom, a crate (perhaps with a sound-dampening cover), or any other area you've noticed your pet seeking during loud noises. Providing music or white noise in the safe place helps some pets.
If your dog does not have a preferred location, you can create one--but do not force a dog to go to a particular area (like a crate) if it increases his anxiety. Training a dog to settle in the safe zone on command can become a relaxation technique he can use during noise events.
Counter-conditioning can decrease fear and provide a distraction. For example, giving a treat-filled toy during thunderstorms can help a dog learn to associate the noise with something positive.
Desensitization begins with playing a recording of the problem sound at a very low volume for a very short time (at a level too low to provoke anxiety). The volume is gradually increased until the dog is able to listen without fear. This can take weeks or months. It is less likely to work for dogs with storm phobia.
Fast-acting antianxiety medications are used as needed for individual noise events, such as Fourth of July fireworks. Most work best if given at least 30 minutes before the noise begins, although some can reduce anxiety in dogs who are already frightened. Examples are alprazolam, trazodone, and a form of dexmedetomidine placed inside the cheek.
Long-term daily medications (such as fluoxetine) can help dogs who have anxieties in addition to noise phobia. They may also reduce overall anxiety in dogs with storm phobia. These drugs can be used in combination with fast-acting medications.
Antianxiety wraps put gentle pressure on the body. Some owners say these products help calm their dogs; others see little difference. A dog pheromone is available as a collar, spray, or diffuser. A recent study showed that the pheromone decreased signs of noise phobia, although other reports have been inconclusive.
