Make plans now to keep your pets safe over the July 4 weekend. Large fireworks shows might be canceled this year, but fireworks stores across the state line are open and home fireworks pose risks for pets.
Fireworks in neighborhoods are traumatic for many animals. The loud bangs are random and sporadic, so they’re hard to predict. For pets at home, neighborhood fireworks are louder than big fireworks shows because they’re closer. And fireworks set off by individuals tend to continue for several hours, often over a few days, instead of being limited to the duration of a fireworks show.
Animals startled by loud noises can bolt unexpectedly. Take these steps to keep your pets from getting lost and increase the chance of finding them if they run off:
Noise phobia, or irrational fear of certain noises, is common in dogs and is often triggered by fireworks. Noise phobia goes further than just disliking loud sounds. Animals with noise phobia have reactions that range from hiding under the bed to destroying parts of the house. Some symptoms, like seeking attention, are subtle. This anxiety condition often gets worse with time and can seriously affect an animal’s safety and welfare.
If you think your pet might have noise phobia, call your veterinarian. Your pet might need a combination of short-term treatment (like antianxiety medication) that you can use right away and long-term behavior modification measures. The sooner you address noise phobia, the better it will be for your pet.
Various therapies have been used to help dogs with noise phobia. Some work better than others. A survey published in May 2020 asked dog owners how they managed their dogs’ fireworks fears and how well various techniques worked. The most effective measures, indicated by at least 69% of owners, were counterconditioning (giving the dog something desirable when the noise occurred), prescription antianxiety medication, and relaxation training. Pressure vests and desensitization using fireworks recordings were less effective. Pheromones, nutraceuticals, and herbal remedies worked for the fewest dogs.
Fireworks contain hazardous substances like fuel, oxidizers (for combustion), and heavy metals. If swallowed, these chemicals can cause vomiting, diarrhea, seizures, liver disease, or kidney disease. Lit fireworks and smoke are obviously a risk to animals’ eyes and skin. Keep your pets completely away from new and used fireworks:

It’s tempting to share some of the Thanksgiving feast with our pets. Not all human food is safe for dogs and cats, though. The best way to avoid a holiday trip to the emergency clinic is to give pets their usual food and keep table food out of their reach. If you (or your guests) do want to give your pets a little bit of holiday food, though, here are some suggestions that are fine for most dogs and cats.
Keep in mind a few rules of thumb. Don’t give them anything that’s dangerous to dogs and cats: fatty food, bones, raw meat, raw eggs, raisins, grapes, currants, onions, garlic, leeks, raw yeast dough, macadamia nuts, chocolate, and the sugar substitute xylitol. For more, see the posts on Thanksgiving safety for pets and human foods that are toxic to pets.
Unseasoned single-ingredient foods are safer than multiple-ingredient dishes because they’re less likely to contain hidden dangers like onion. Moderation is key; too much of any food can upset a pet’s stomach. And remember that these suggestions don’t apply to pets with food allergies or digestive problems.
A bite of cooked skinless, boneless turkey meat is safe for most dogs and cats. Keep portion size in mind; a 10-lb dog or cat does not need the same amount of turkey that a person would eat. Take these precautions:
Defatted turkey or chicken broth
Pan drippings and gravy are too high in fat for dogs and cats. But a spoonful or two of defatted broth is usually fine for dogs. Don’t give broth to your cat unless you can be absolutely sure it wasn’t made with onions, leeks, shallots, or garlic; try tuna juice instead.
Vegetables and fruits
Dogs like vegetables more than you might think. Avoid grapes, raisins, currants, veggies cooked with fat or butter, and vegetable casseroles (that green bean casserole with the crispy onions on top? no). Stick with plain veggies and fruits, either raw or cooked without seasoning. My own dogs highly recommend all of these:
A small piece of bread, cornbread, or biscuit is generally safe for dogs and cats. Keep unbaked dough out of their reach; raw yeast dough can cause ethanol poisoning. Watch for added fats and seasonings (no onion focaccia or garlic bread). A bite of plain bread is safer than dressing or stuffing, which is likely to contain fat, onion, and possibly raisins or currants. Also avoid store-bought baked goods that might contain artificial sweeteners like xylitol.
For pets eating prescription or limited-ingredient diets
The best approach for pets with medical needs or food allergies is to close them in a room away from the kitchen and dining area. Guests might not realize that these pets have dietary restrictions. If your pet is eating a special diet and you’d like to give treats, ask your veterinarian for safe options. Some prescription diet manufacturers have developed treats that are compatible with their diets.

Chocolate is one of the top 10 animal toxins reported to the ASPCA Animal Poison Control Center each year. As you shop for Halloween candy and get ready for the holiday season, remember to keep the candy bowl and baking supplies out of reach of your dogs. (Chocolate is dangerous for cats too, but they’re less likely than dogs to eat it.)
What’s Toxic About Chocolate?
The main toxic components of chocolate are methylxanthine compounds, specifically theobromine and caffeine. Cocoa beans and their hulls have relatively high methylxanthine levels. Cocoa butter (the fat from the cocoa bean) contains very little methylxanthine.
Humans process methylxanthines in the body at a different rate than dogs do, so foods containing chocolate and caffeine that are safe for people can be very risky for dogs.
As far as toxicity goes, not all chocolate is created equal: some types of chocolate are more dangerous to dogs than others. Products with high concentrations of cocoa liquor, which is made from cocoa beans, are the most toxic for dogs.
In general, the darker the chocolate, the more dangerous it is for dogs. Dry cocoa powder is more toxic than dark sweet chocolate, and dark sweet chocolate is more toxic than milk chocolate. Mulch made from cocoa bean hulls contains theobromine and is unsafe for dogs. White chocolate has very low methylxanthine levels and doesn’t cause chocolate poisoning.
Chocolate-containing foods can be dangerous for dogs for other reasons too. Dogs that eat food with a high fat content—this includes white chocolate—can develop pancreatitis, a disorder of the pancreas. Baked goods and candies may contain raisins, macadamia nuts, xylitol (a type of sweetener), or other ingredients that are hazardous to dogs.
How Much Chocolate Is Dangerous?
The severity of chocolate poisoning depends on 3 factors:
These 3 factors determine the dose of methylxanthine that a dog has received. The higher the dose, the more severe the consequences.
Figuring out the amount of methylxanthine in a chocolate product isn’t always simple because cocoa content varies. You can get a general idea of your pet’s risk by using a chocolate toxicity calculator like the one at veterinaryclinic.com. The ASPCA Animal Poison Control Center has a mobile app that includes a easy-to-use chocolate calculator and information on other potential hazards.
Signs of Chocolate Poisoning
The signs of chocolate poisoning depend on the dose of methylxanthine. Dogs that eat chocolate can also develop pancreatitis (from the fat content) or have toxic effects from other ingredients. Signs of methylxanthine poisoning usually appear within 6 to 12 hours and include the following:
What to Do if Your Dog Eats Chocolate
If your dog eats chocolate or a caffeine-containing product, estimate how much she ate and make a note of the ingredients. Save the product label if possible. Call your veterinarian’s office if you’re not sure if the amount was safe. If your dog has symptoms of chocolate poisoning or if the amount or type of chocolate was dangerous (for example, if your Chihuahua ate a 2-oz bar of dark chocolate), seek veterinary care right away.
Dogs with chocolate poisoning may need to be hospitalized for treatment. Your veterinarian might induce vomiting or might recommend that you do this at home—but don’t try to make your dog vomit without checking with your veterinarian first (induced vomiting is not always the best or safest approach). The prognosis depends on the severity of the symptoms.

Toxins from algae in a pond killed 3 dogs in Wilmington earlier this month. The same type of algae has been found in a public park pond in Charlotte. The only way to know if algae is harmful is by testing the water in a laboratory, so for safety, keep your dog away from all scummy or discolored water.
Harmful Algal Blooms
Algae are tiny plantlike organisms that live in water. Some algae produce toxins that cause serious illness. Under certain conditions, algae grow quickly into collections called algal blooms. Algal blooms are most likely to form in warm water that is high in nutrients like nitrogen. Hot weather and stagnant water increase the chance of algal growth.
Algal blooms can form in either fresh or salt water. The most common type of harmful algae in fresh water is cyanobacteria, or blue-green algae. Another type of algae causes red tide in salt water.
Avoid water with signs of potentially harmful algal blooms:
Symptoms of Exposure
People and animals can be exposed to algal toxins through skin contact with contaminated water, by drinking contaminated water or eating contaminated food (like fish), or by inhaling water droplets in windblown spray. Dogs are typically exposed when they play or wade at the edges of bodies of water with algal blooms.
Not all algal blooms are toxic. But with some types of algae, exposure to only a small amount of toxin can be fatal within hours or days. Algal toxins can damage the liver, nervous system, kidneys, and digestive tract. Symptoms depend on the type of toxin and the amount of exposure and include the following:
What to Do if Your Pet Is Exposed
If your dog comes in contact with questionable fresh or salt water, bathe or at least rinse him off with clean (tap) water right away, before he licks his fur. Take precautions to avoid exposure to yourself; wear gloves or wash your hands after rinsing your dog.
Take your dog to a veterinary clinic if she has swallowed water containing algae or has licked her fur after wading in water with an algal bloom. Symptoms of toxin exposure constitute a medical emergency, so seek veterinary care immediately if your dog is vomiting or stumbling after water contact.
The Centers for Disease Control and Prevention (CDC) and the NC Department of Health and Human Services (DHHS) recommend these precautions:

A recent study of 114 recipes for homemade diets for cats found that all of the diets were nutritionally inadequate in some way. Most of the recipes, which were either posted online or published in books, were deficient in at least 1 nutrient. Some recipes included ingredients (like onions and garlic) that are toxic to cats. Other studies have found similar problems in recipes for home-cooked diets for dogs.[2-4]
Some pet owners choose to make their own dog or cat food because of a pet with food allergies, a desire to feed natural products, a distrust of commercial pet food, or another reason. Preparing dog and cat food at home is time-consuming and expensive, and owners who undertake it generally just want to take good care of their pets. Dogs and cats rarely require home-prepared diets, but if you decide to make your pet’s food yourself, check the resources for safe recipes at the end of this article.
Potential Problems With Homemade Pet Food
Recipes for home-prepared dog and cat diets are often not nutritionally complete and balanced. Deficiencies in nutrients like iron, taurine, and calcium can lead to anemia, heart disease, and bone disease. Because many recipes are deficient in the same nutrients, rotating among different diets and ingredients won’t necessarily balance the diet.
Home-prepared diets must be supplemented with the right mix of vitamins and minerals. General-purpose multivitamins for dogs or cats are usually not sufficient for pets eating homemade diets. Some vitamin supplements are made for pets eating fortified commercial diets, not those eating homemade diets with lower vitamin and mineral levels.
Oversupplementation is also a possible problem. Too much vitamin D, for example, can damage the kidneys. The choice and amount of nutrients to include in a supplement depend on the ingredients of the chosen diet.
Some homemade diet recipes include potentially unsafe ingredients. Others are based on misconceptions about dog and cat nutrition. Dogs and cats don’t need to eat raw meat, which poses a risk of bacterial contamination for the pet eating it and also for people in the household.[5,6] Bones in the food can damage the digestive tract unless they are ground up. Many recipes (and commercial diets) promote the mistaken idea that there is something wrong with feeding grain to dogs. In fact, grain-free diets might be linked to heart disease in dogs.
Where to Find Recipes
The safest homemade diets for dogs and cats are formulated by board-certified veterinary nutritionists. These specialist veterinarians have extensive training in animal nutrition. Veterinary nutritionists develop recipes for healthy animals and can also customize diets for animals with diseases or specific nutritional needs.
If you use a recipe from a veterinary nutritionist, be sure to follow the recipe and feeding instructions exactly. Ingredient substitutions can change the nutritional balance of the diet.

Microchips are a type of permanent identification that helps families reunite with lost pets. Pets should also have visible forms of identification like collar tags, but microchips can’t be pulled off by accident and are an important backup. Microchips are also required in some situations, like transporting animals.
Microchips connect owners to lost pets only if the owner’s contact information is registered in a microchip database. The United States does not have a central microchip registry. Microchip manufacturers and pet recovery services maintain their own databases. It’s essential to keep your contact information up to date in your pet’s microchip database.
If you’re not sure where your pet’s microchip is registered, enter the microchip number in the American Animal Hospital Association microchip lookup tool:
If you don’t know the microchip number, your veterinarian’s office can scan your pet if the number is not already entered in your pet’s medical record.
What Are Microchips?
Microchips are radiofrequency identification transponders about the size and shape of a grain of rice. Microchips are implanted under the skin. In dogs and cats, they are implanted between the shoulder blades. You can’t usually feel a microchip under your pet’s skin, but you can see it on an x-ray image.
A microchip is not a GPS device and can’t be used to track your pet.
How Are Microchips Implanted?
A microchip is injected under the skin through a needle, similar to the way a vaccine is injected (although the needle is a bit larger). Animals do not need anesthesia during microchip insertion. Your veterinarian can implant a microchip during an office visit.
How Does Scanning Work?
Shelters and veterinary clinics routinely scan stray dogs and cats for microchips. If the animal has a microchip and the owner’s information in the database is accurate, the staff can contact the owner.
A microchip scanner emits a low-power radiofrequency signal that activates the microchip. When a microchip scanner passes over a microchip, the chip transmits a number that the scanner displays on a screen. The number is unique to that microchip, so once you’ve registered it, it’s also unique to your pet.
Microchip manufacturers around the world make microchips that use different radiofrequencies. Not all scanners detect all microchip frequencies. Universal scanners read multiple frequencies. Microchips that meet the International Standards Organization (ISO) global standard transmit a specific radiofrequency that can be read by an ISO-standard scanner. Some countries require ISO-compliant microchips for imported animals.
Are Microchips Safe?
The benefits of microchipping are generally far greater than the potential risks. Adverse reactions to microchips are rare. Animals could bleed a little or have mild, short-lived discomfort at the injection site. Infection and swelling at the injection site are possible but not common. Microchips can theoretically cause inflammation that leads to cancer, but almost all reports of cancer near a microchip implantation site have been in laboratory rodents. Only a few cases in cats and dogs have been reported, and in most it was not clear if the cancer was linked to the microchip.
Are Microchips Reliable?
It’s possible for an animal to have a microchip that isn’t found on a scan. A microchip might use a different radiofrequency than the scanner can detect (if the scanner isn’t universal). Microchips occasionally migrate under the skin, usually to the side of the shoulder or front leg. People scanning for microchips typically scan a wide area of the body for this reason. And a microchip might not work at all (or stop working). Ask your veterinarian to check your pet’s microchip at the next clinic visit.

Antifreeze is toxic to animals and people. Even a small amount of antifreeze licked from a paw or lapped from a puddle could kill a cat or dog. If you think your pet has been exposed to antifreeze, contact a veterinarian immediately.
The main ingredient of most types of antifreeze is ethylene glycol, a type of alcohol. Ethylene glycol has a naturally sweet taste.
Protect your pets by keeping them away from fluids that have leaked out of cars. Store antifreeze in sealed containers out of the reach of animals and children. Consider using antifreeze made of propylene glycol instead of ethylene glycol; it’s safer for pets.
Sources of ethylene glycol
Antifreeze (radiator coolant) is used in the engines of cars and other motor vehicles. The risk of exposure might be higher when seasons change and people change the antifreeze in their cars. Dogs have also been poisoned by drinking toilet water that has had antifreeze added to keep it from freezing.
Although antifreeze is the most common source of ethylene glycol poisoning in dogs and cats, ethylene glycol can be present in other products:
Signs of poisoning
The earliest symptoms are caused by the ethylene glycol itself. Symptoms that appear later are caused by toxic substances produced when ethylene glycol is broken down in the liver. The symptoms of poisoning occur in 3 stages.
Stage 1: During the first 12 hours, symptoms are similar to those of alcohol intoxication:
Stage 2: From about 12 to 24 hours after ingestion, the animal may seem to improve as “drunken” symptoms go away. But toxic products of ethylene glycol begin to alter the body’s acid-base balance and damage the kidneys. Signs include the following:
Stage 3: Between 12 and 24 hours after exposure (cats) or 36 and 72 hours (dogs), the kidneys stop working. The patient shows symptoms of acute kidney failure and other problems:
Diagnosis and treatment
A blood test can detect ethylene glycol in the first few hours after ingestion. After a few hours, blood and urine tests begin to show evidence of acid-base disturbances and kidney damage. Diagnosing ethylene glycol poisoning can be tricky if no one saw the pet swallow antifreeze and the pet doesn’t arrive at the veterinary clinic until it is showing signs of kidney failure.
The sooner treatment begins, the better the prognosis. An antidote to ethylene glycol is available and should be given soon after exposure. This drug stops ethylene glycol from being converted to toxic substances. After most of the ethylene glycol has been metabolized by the liver, the antidote is less likely to be effective.
Other treatment is given to correct the body’s acid-base balance and support kidney function. Pets with ethylene glycol poisoning will probably need to stay in the hospital for a few days, even if the poisoning is caught early.
The prognosis is good for animals that begin treatment soon after ingesting antifreeze. For those that develop kidney failure, the prognosis is guarded to poor.

Are you tempted to skip your pets' heartworm and flea medicines during the winter? Dogs and cats actually need parasite prevention all year round. Year-round parasite control for pets helps keep the whole family safe from parasite-transmitted disease.
Warm spells during the winter are common in North Carolina, so we can’t count on cold temperatures to suppress insects that carry disease. Mosquitoes, fleas, and ticks can also live through the winter in areas that are protected from the cold.
Heartworms are transmitted by mosquitoes. Mosquitoes become active when the temperature rises above about 50°F (which happens routinely in North Carolina during the winter). But occasional warm winter days aren’t the only reason pets need year-round heartworm prevention.
Heartworm preventives work by killing tiny heartworm larvae that are already in an animal’s bloodstream. These larvae came from mosquitoes that bit the animal in the past month or more. Skipping a month of heartworm prevention could mean that your dog isn’t protected from heartworm larvae that he was exposed to when it was warmer. The American Heartworm Society recommends giving heartworm preventives all year round.
Intestinal parasites (worms)
Some heartworm preventives also control intestinal parasites like hookworms and roundworms. These parasites can infect humans too. Giving parasite prevention to your pets throughout the year is a sensible safety measure.
Fleas don’t just causing itching. They also transmit diseases like cat scratch disease, tapeworms, and plague.
Fleas lay eggs that drop off the infested animal into the environment. This means that flea eggs are present everywhere the animal has been, including inside a home. After the eggs hatch, the larvae and pupae (intermediate stages) can stay dormant for weeks to months before becoming adult fleas.
Because fleas can go through their life cycle indoors, they don’t need to wait for warm weather to develop into adult fleas. Flea infestations are easier to prevent than to treat, so the best chance of avoiding a flea problem is to give your pets year-round flea prevention.
Ticks carry many diseases that affect both pets and people. Some tick species, including the type that transmits Lyme disease, are active during the winter when the temperature is above freezing.
Ticks tend to live in leaf litter, crevices of buildings, and underbrush. When they’re ready to take a blood meal, they move to grassy areas or shrubbery near paths and latch onto a passing animal or person.
Ticks can be hard to see through fur, so you might not realize that your dog has picked up a tick. Because of the risk of serious disease, the safest approach is to limit tick exposure: control ticks around your home and give your pets tick preventives recommended by your veterinarian.

On December 3, the Food and Drug Administration (FDA) warned pet owners of potentially toxic vitamin D levels in some dog foods. The affected foods have been recalled. A list of recalled brands is posted on the FDA website: https://www.fda.gov/AnimalVeterinary/NewsEvents/ucm627485.htm.
Vitamin D: both an essential nutrient and a poison
Vitamin D helps regulate calcium and phosphorus levels in the body. This vitamin is necessary for bone health and for normal muscle and nerve function. Vitamin D is fat soluble, not water soluble, so the body stores extra vitamin D in the liver and fatty tissues instead of expelling it in the urine.
Excessive levels of cholecalciferol, the active form of vitamin D, lead to dangerously high levels of calcium and phosphorus in the blood. Calcium deposits form in body tissues, especially tissues that have a large blood supply, like the kidneys. Mineral deposits in the kidneys cause kidney failure, which is the usual cause of death in animals with vitamin D poisoning.
Rodenticides (rat and mouse poisons) that contain cholecalciferol are typical sources of vitamin D poisoning in pets. Even small amounts of cholecalciferol-containing rodenticides can cause severe kidney damage in dogs and cats. Human vitamin supplements and contaminated pet foods can also cause cholecalciferol toxicosis in pets.
According to the FDA, some of the recalled dog foods contained 70 times the expected level of vitamin D.
Symptoms of vitamin D poisoning
Watch for these symptoms, especially if your dog has been eating one of the recalled foods:
Signs of poisoning usually appear within a day or two after an animal ingests a toxic level of vitamin D. By this time, the kidneys have already been affected. Blood tests show increased levels of calcium, phosphorus, and markers of kidney disease.
What you should do
If your dog has been eating one of the recalled diets, stop feeding the diet immediately. The FDA recommends disposing of the food in such a way that other animals (including wildlife) and children cannot reach it.
Seek veterinary care immediately if you think your pet might have vitamin D poisoning. The symptoms are not specific to vitamin D toxicosis (lots of things cause vomiting), so your veterinarian will perform bloodwork and possibly other diagnostic tests. Take either the bag of dog food or a photo of the label, including the lot number, to the clinic with you if your dog might have eaten a recalled food.
The sooner treatment starts, the better the chance of recovery. Treatment involves hospitalization for several days, intravenous fluids, medications to help flush calcium out of the body and support kidney function, and repeated blood tests to monitor kidney function and levels of calcium and phosphorus.
The FDA suggests that pet owners and veterinarians report possible cases of vitamin D poisoning through the online Safety Reporting Portal.

Keep your pets safe, happy, and out of the emergency clinic with these Thanksgiving safety tips.
No fatty food
Turkey skin, meat drippings, gravy, bacon, butter, and other fatty foods can cause pancreatitis (inflammation of the pancreas) in dogs. This potentially painful condition leads to vomiting, loss of appetite, and dehydration. Pancreatitis can land a dog in the veterinary hospital for intensive care. Any dog can develop pancreatitis, but some breeds are more prone to it than others. Miniature schnauzers are the poster dogs for pancreatitis.
Don’t give your pet a turkey leg. Bones can get stuck in the digestive tract (esophagus, stomach, or intestines). Sharp bones can puncture the digestive tract.
No turkey brine
The solution used to brine turkeys might taste great to pets, but the high salt content can lead to salt toxicosis. Symptoms include vomiting, diarrhea, loss of appetite, increased thirst, tremors, and seizures.
No raw meat or raw eggs
Raw meat and eggs can carry harmful bacteria like salmonella. Dogs and cats are just as susceptible to food poisoning from bacteria as humans are.
No raisins, grapes, or currants
Even small amounts of these fruits can cause kidney damage in dogs.
No raw bread dough
Raw yeast dough expands in a dog’s stomach, potentially causing bloat. Raw yeast dough also produces ethanol, which can give a pet alcohol poisoning.
No chocolate or artificial sweeteners
Chocolate is toxic to dogs and cats; the darker the chocolate, the higher the risk. Many low-sugar and sugar-free foods (including some baked goods) contain xylitol, a sweetener that is very dangerous for dogs.
No onions or garlic
Cats are highly sensitive to compounds in onions, garlic, leeks, and chives that can cause anemia. Dogs and cats may also develop upset stomachs from eating these vegetables.
Take out the trash
Bones, corncobs, and string used to truss a turkey are all enticing to pets that have access to the garbage can. These items can cause intestinal blockages. Keep kitchen trash sealed away from your pets while you’re preparing the big meal. If you plan to block your pets out of the kitchen, remember that children and guests might leave interior doors and baby gates open.
Watch the exits
Pets may not be used to guests coming and going, and your company might not be prepared to stop your pets from dashing out of an open door. Make sure your pets all have identification (collar tag, microchip, or both) in case of an escape.
Give your pets a safe space
Give your pets a quiet place to get away from the action. Some pets are much more comfortable staying safely in another room the whole time guests are at your house. Guests who aren’t accustomed to having pets underfoot might appreciate this too.
