Laurie Anne Walden, DVM  Yulia Khlebnikova via Unsplash Chip, snack, and cereal bags pose a suffocation risk that pet owners might not know about until it’s too late. Dogs and cats have died after putting their heads in snack bags and other food containers.
Of the various types of food containers, plastic and Mylar-lined bags are the biggest suffocation hazards. When an animal with its head in a bag inhales, the bag tightens around the head, cutting off airflow. The animal might not be able to remove the bag on its own. Death can occur in just a few minutes. Preventive Vet conducted an online survey about pet suffocation and received 1354 responses from 2014 through 2018. The responses from pet owners whose pets died or almost died of suffocation are summarized here. Most common culprits:
Where pets got hold of the bags:
More than one-third of pet owners were home when their pet suffocated. Of the owners who were away from home, 18% were gone for less than 15 minutes. Animals of all sizes are at risk. According to the survey responses, more than half of the dogs who suffocated were larger than 30 lb, and some were over 60 lb. Prevention Simply being aware of the risk is a big part of keeping your pets safe. A lot of us have probably left chip and other food bags where our pets can reach them. Here are some steps you can take:

The problem ingredients—imidazoline decongestants, phenylephrine, and xylitol—are common in products to treat allergies, colds, flu, and red eyes.
If your pet chews a nasal spray or eye drop bottle, call your veterinarian or an animal poison control hotline immediately. This type of poisoning is a medical emergency. Even small amounts of ingested product can be dangerous. Pet poison hotlines (consultation fees apply):
Imidazoline Decongestants Decongestants in the imidazoline class are found in many nasal sprays and eye drops that reduce nasal congestion and eye redness. Some of the drugs in this group are oxymetazoline, naphazoline, tetrahydrozoline, tolazoline, and xylometazoline. A few of the many brands that contain imidazolines are Afrin, Clear Eyes, Mucinex, Opcon, Privine, Sinex, Visine, and Zicam. Imidazolines affect the heart, circulation, digestive system, and nervous system. They decrease nasal congestion and eye redness by narrowing small blood vessels in the nose and eyes. Symptoms of imidazoline poisoning appear as soon as 15 minutes after ingestion of a large amount or a few hours after ingestion of a small amount. The symptoms last from about 12 to 36 hours and include the following:
Animals with imidazoline poisoning need to be hospitalized for treatment and monitoring. Reversal agents for imidazolines are available. Phenylephrine Imidazolines and phenylephrine have similar effects on the body. Like imidazolines, phenylephrine acts as a decongestant by shrinking small blood vessels in the nose. Phenylephrine is available in oral forms, nasal sprays, eye drops, and hemorrhoid creams. Two brands of nasal spray that contain phenylephrine are Little Remedies and Neo-Synephrine. Ingestion can cause vomiting, agitation, hyperactivity, and increased blood pressure.[2] Xylitol Some nasal sprays, including some with labels reading “natural saline,” contain xylitol. One example is Xlear nasal spray. Xylitol is harmless in humans, but in dogs it causes a dangerous, rapid drop in blood sugar and can also cause liver damage. The best approach is to keep all remedies (prescription, nonprescription, and “natural”) out of reach of pets and never assume that a product that’s safe for children is also safe for animals.

But what about insects that our pets catch and swallow? Most are harmless, but a few are unsafe for pets. As warm weather arrives, keep an eye out for insects that can cause trouble if they’re eaten.
Pesticides and insecticides can also be toxic to pets. Keep these products out of your pets’ reach and use them only according to the manufacturer’s instructions. Dogs and cats are most likely to get a toxic dose if they’re sprayed with the product or eat a significant amount. A pet that eats a single pesticide-covered insect would ingest a little bit of the product, but the amount would probably be too small to cause a problem (call your veterinarian if you’re unsure or if your pet shows any symptoms). Caterpillars Caterpillar hairs can be irritating to the touch, and some types of hairs release a toxin. Fur typically protects dogs’ and cats’ skin from the stings of caterpillar hairs. If a pet eats a caterpillar, though, the hairs can irritate the mouth and throat. Symptoms include drooling, pawing at the mouth, shaking the head, vomiting, and trouble swallowing. Processionary caterpillars (found in Europe, North Africa, and Asia) produce a toxin that causes an especially severe reaction.[1,2] Fireflies Fireflies are highly toxic to lizards, amphibians, and birds. Ingestion of a single firefly can kill a bearded dragon. Fireflies contain lucibufagins, which are chemicals that cause heart damage in susceptible species.[3] Asian Lady Beetles Asian lady beetles (Harmonia axyridis) look a lot like ladybugs, but unlike ladybugs they gather in large numbers and come inside houses in cold weather. As a defense mechanism, they secrete an irritating chemical compound. One published report describes a dog with oral trauma similar to chemical burns caused by 16 Asian lady beetles stuck to the roof of the mouth.[4] Blister Beetles Blister beetles (family Meloidae) produce a toxin called cantharidin, an irritant that causes blistering on contact with the skin, mouth, or digestive tract. Cantharidin poisoning is most common in horses that eat alfalfa hay contaminated with blister beetles. Exposure can be fatal to horses. Other species, including dogs, cats, rabbits, and people, are also susceptible to cantharidin poisoning.[5] Walking Sticks The insects known as walking sticks (order Phasmatodea) use camouflage as their main defense mechanism, but some of them also secrete a chemical that can burn the eyes or mouth. Anisomorpha buprestoides, a stick insect found in the southern United States, can aim this secretion directly at the face of a predator. Severe eye damage has been reported in humans and a dog.[6] Bombardier Beetles Brachinus beetles are called bombardier beetles because they secrete a toxic chemical that they aim at predators in what is usually described as “explosive discharge.” This chemical irritant is released at a boiling temperature.[7] Although I did not find any research reports of bombardier beetle poisoning in dogs or cats, I can’t imagine that eating one would be a comfortable experience.

At the time of the alert, 70 dogs had died and more than 80 were sick (not all of them officially confirmed as having aflatoxin poisoning).[1]
Other pet foods have been recalled in the past because of aflatoxin. For a list of foods included in the current recall, see the FDA alert: https://www.fda.gov/animal-veterinary/outbreaks-and-advisories/fda-alert-certain-lots-sportmix-pet-food-recalled-potentially-fatal-levels-aflatoxin Cause Aflatoxins are produced by molds (Aspergillus species) that grow on grains like corn. Animals are exposed by eating contaminated animal diets or moldy corn, peanuts, or other foods. Food doesn’t have to look moldy to be contaminated with aflatoxins. Because commercial dog food is typically the main component of a dog’s diet and dogs usually eat from a single bag of food until it’s finished, even low levels of aflatoxin in the food can accumulate in the body and cause symptoms.[2] Symptoms The liver is the main organ affected. Liver damage causes nonspecific digestive tract symptoms. Severe liver damage reduces the ability of the blood to clot and can lead to central nervous system problems. Death occurs quickly in some animals with aflatoxin poisoning. Symptoms include the following:
Diagnosis The symptoms of aflatoxin poisoning aren’t specific and could have a number of causes. Diagnosis begins with history, physical examination, and blood and urine tests. If test results show liver damage and a toxin is suspected, the next step is obtaining a complete history of everything the animal has been exposed to, including all foods and treats. Food samples and possibly tissue samples from the body can be sent to a laboratory to test for aflatoxin. Treatment Treatment consists of supportive care and management of problems (like blood clotting disorders) caused by liver failure. Specific treatment depends on the individual patient’s needs. What You Should Do The FDA recommends that pet owners take these steps:

Keep all medications out of reach of your pets, and check with your veterinarian before giving a pet any medication—even remedies that are safe for children.
Cold medications are often sold as combination or multisymptom products containing more than 1 active ingredient. If your veterinarian recommends giving your pet a nonprescription medication, read the product label carefully to be sure it contains only the medication your veterinarian has approved. Ingestion of some cold and flu products (especially oral decongestants, nasal sprays, eye drops, and pain relievers) is a medical emergency in animals. If your pet is exposed, contact a veterinary clinic or pet poison hotline:
Oral Decongestants Decongestants are often added to allergy medications and combination cold and cough remedies. If your veterinarian has recommended a nonprescription antihistamine for your pet, be sure that the product you use does not contain a decongestant. Look for label wording like congestion, stuffy nose, runny nose, multisymptom, or sinus pressure; these probably mean that the product includes a decongestant. Names of products containing decongestants might end in D (for example, Claritin-D and Mucinex D) or PE (as in Sudafed PE). Pseudoephedrine and phenylephrine are the most common oral (by-mouth) decongestants. Both are dangerous for animals. In the United States, pseudoephedrine is sold without a prescription but with restrictions: it’s sold only in limited quantities, is usually kept behind the pharmacy counter or in a locked cabinet, and requires that the buyer show identification. If you’re not sure of the ingredients of your cold medication, knowing whether you took it from an open shelf or had to ask the pharmacist for it will help you figure out whether it is likely to contain pseudoephedrine. Pseudoephedrine stimulates the cardiovascular system and certain nervous system pathways. It reduces nasal congestion by shrinking tiny blood vessels in the nose. It has a very narrow margin of safety in animals, meaning that a small dose can have serious consequences for a dog or cat. Symptoms of pseudoephedrine toxicity include the following:
The time of symptom onset depends on the formulation. With immediate-release products, symptoms can begin within minutes of ingestion. With extended-release products, symptoms might not appear for several hours.[1] Phenylephrine is an ingredient in oral cold remedies, hemorrhoid creams, nasal sprays, and some eye drops. Animals are exposed by swallowing the product. The most common symptom is vomiting; other symptoms are similar to those of pseudoephedrine toxicity. Phenylephrine is not as toxic as pseudoephedrine at low doses.[2] Nasal Sprays and Eye Drops Oxymetazoline, tetrahydrozoline, naphazoline, and xylometazoline are imidazolines, a class of decongestant used in nasal sprays and eye drops (examples are Afrin and Visine). Animals—usually dogs—who chew the bottle and ingest the liquid can develop vomiting, lethargy, incoordination, slow heart rate, tremors, and coma. Imidazoline ingestion can be fatal.[3] Some nasal sprays contain xylitol, a sweetener that is safe for humans but toxic to pets. Plain saline nasal rinses with no ingredients other than water and salt should be safe if accidentally ingested, but don’t squirt them up your pet’s nose. Pain Relievers Combination cold and flu products commonly contain pain relievers, most of which are unsafe for dogs and cats. Acetaminophen is extremely toxic to cats even at low doses. It causes liver failure, damage to hemoglobin in red blood cells, and death. It can also cause liver damage in dogs. Ibuprofen and naproxen are in a class of pain relievers called nonsteroidal anti-inflammatory drugs. In dogs and cats, these medications can cause stomach ulcers, digestive tract bleeding, kidney damage, and liver damage. Cough Suppressants and Cough Drops Dextromethorphan is an antitussive, or cough suppressant, included in many cough remedies and combination cold and flu products. Animals who ingest dextromethorphan can develop vomiting, lethargy, rapid heart rate, and seizures.[4] Potentially toxic ingredients in cough drops include xylitol, which causes a dangerous drop in blood sugar in dogs, and benzocaine, which can cause upset stomach and possibly damage to red blood cells. “Natural” Remedies In high enough doses, zinc can damage red blood cells. Essential oils like menthol, camphor, and eucalyptus oil can cause skin reactions if applied topically. If swallowed or absorbed through the skin, these oils can cause symptoms ranging from vomiting to nervous system problems. References 1. Pseudoephedrine toxicity in pets. ASPCApro.

Keep your cat safe from these common household dangers when you’re preparing for the season.
Strings Ribbons, tinsel, yarn, twine, fishing line, thread, garland, and other long strings are hazardous if swallowed. A string in the digestive tract can cause a linear foreign body obstruction. Cats with digestive tract obstruction need surgery to prevent serious damage to the intestines. Keep this danger in mind when choosing holiday decorations. Wide ribbons might be less of a swallowing hazard than narrow ribbons. Shiny Objects Tinsel is especially attractive to cats because it’s sparkly, so a long string of tinsel is an intestinal obstruction waiting to happen. Watch out for glass ornaments that can cut paws if they mysteriously land on the floor and break. Expect that your cats will treat all glittery and shiny items as cat toys and decorate accordingly. Wood and fabric ornaments are safer than glass ornaments in a household with cats. The Tree With Christmas trees, the goal is to prevent damage to your cat and damage to property. Christmas tree dangers to cats include tree water (might contain preservatives or pesticides), swallowed pine needles, broken or swallowed ornaments, electrical wires, and being hit by a falling tree. If your cat ignores the tree, you might not need to do anything more than keep breakable ornaments on high branches, cat-safe (or no) ornaments on low branches, and a close eye on your cat when he’s in the room with the tree. But if your cat is young, curious, adventurous, or new to your home, assume he’ll want to climb the Christmas tree. The safest approach is to either not have a tree or to close the door and keep the cat out of the room. If your cat has access to the tree, use a sturdy base and secure the tree to the ceiling or walls so it can’t tip over. Don’t use any breakable ornaments if your cat is a climber. To prevent electrocution, keep the tree lights unplugged when you’re not watching your cat. Try giving your cat a more attractive alternative, like a high perch and new toys or a cat Christmas tree (maybe made from a cardboard box). You could try bitter orange spray or an unappealing floor covering around the tree (aluminum foil, adhesive paper with the sticky side up, or a nonslip rug gripper with the pointy side up), but don’t count on deterrents like these to keep your cat out of the tree. Other Plants Lilies are among the most dangerous plants for cats; don’t bring them in your house at all if you have a cat. Holly, mistletoe, and amaryllis are toxic to cats to some degree. Poinsettias are mildly toxic to cats. Flames and Electrical Wires Cats like to push things off tables and are curious about new items in their living space. Don’t leave a cat alone with lit candles, which are a fire hazard if knocked over. Cats will also chew on electrical cords, so cover the cords and keep lights and other electrical decor unplugged when not in use. Human Food Onions, leeks, chives, and garlic are toxic to cats. Chocolate, alcohol, raw bread dough, fatty food, raw eggs, raw meat, and bones are also dangerous for cats. See the blog post on human foods that are toxic to pets for more information. If you’d like to share some of your holiday meal with your cat, see the post on Thanksgiving foods that are safe for dogs and cats. Photo by Jessica Lewis Laurie Anne Walden, DVM  Xylitol is a sugar substitute that is safe for humans but toxic to dogs. It is an ingredient in sugar-free gum and a variety of foods, especially products for people who have diabetes or need food with a low glycemic index. Xylitol is added to some oral care products because it slows the growth of bacteria that cause dental cavities.
Products that contain xylitol might or might not be labeled as being sugar free or low in sugar. Xylitol is found in products like these:
Effects in Dogs Xylitol is safe for most animals, but dogs don’t metabolize xylitol the same way as other species. Compared with humans, dogs absorb more of the xylitol they ingest and process it more quickly. Xylitol causes dogs’ insulin levels to surge, resulting in rapid hypoglycemia (low blood sugar level).[1,2] Ingestion of larger amounts of xylitol can damage the liver and interfere with blood clotting.[3] Symptoms of xylitol poisoning in dogs can appear as soon as 30 minutes after ingestion but might be delayed for several hours. These are some of the common symptoms:
Other sugar substitutes and artificial sweeteners (sorbitol, aspartame, sucralose, and saccharin) should be safe for dogs.[2] Xylitol does not seem to be toxic to cats.[4] What to Do If your dog eats sugarless gum or another product that might contain xylitol, call a veterinary clinic or an animal poison control hotline right away. Keep the packaging if possible so the amount of xylitol your dog ingested can be estimated. Do not try to make your dog vomit. Induced (forced) vomiting can be dangerous for a dog whose blood glucose level is already dropping.[1] Treatment usually involves hospitalization, intravenous medications to correct hypoglycemia, and continued monitoring of laboratory values. Dogs with liver involvement and more serious symptoms need more intensive treatment. Dogs that ingest small amounts of xylitol and are treated promptly tend to recover well. The prognosis is poorer for dogs that develop liver damage and blood clotting problems.[2] How to Keep Your Dog Safe Keep candy, baked goods, and other products that might contain xylitol away from your dog (watch out for counter surfers!). If you keep gum or mints in your purse, don’t leave your purse where your dog can reach it. Don’t brush your dog’s teeth with toothpaste meant for humans. Read product labels to check for artificial sweeteners; sorbitol should be OK but xylitol is not. References 1. DuHadway MR, Sharp CR, Meyers KE, Koenigshof AM.

Most wild mushrooms aren’t dangerous, but some are fatal if eaten. Keep your pets safe by removing wild mushrooms from their environment.
Because it’s not easy to know if a wild mushroom is poisonous, treat any wild mushroom ingestion as a medical emergency. If your dog or cat eats wild mushrooms, call an emergency animal clinic, your veterinary clinic, or a pet poison hotline right away. Don’t wait until your pet gets sick before you call. Some of the most toxic mushrooms don’t cause symptoms until hours after they’re swallowed. Pet poison hotlines (fees might apply): ASPCA Animal Poison Control: 888-426-4435 Pet Poison Helpline: 855-764-7661 Photos of toxic mushrooms in North Carolina: NC State Extension Gardener Plant Toolbox: mushrooms Symptoms Symptoms of mushroom poisoning depend on the type of mushroom and the amount eaten. Toxic mushrooms can be categorized by the type of problem they cause: liver and kidney failure, central nervous system effects, muscarinic reactions, hallucinations, or gastrointestinal irritation.[1] Liver and Kidney Failure The mushrooms responsible for the most deaths are in the Amanita, Galerina, and Lepiota genera.[2] Examples are Amanita phalloides (death cap), Amanita bisporigera (destroying angel), and Galerina autumnalis (autumn skullcap). The toxic compounds in these mushrooms are amatoxins, phallotoxins, or virotoxins. These toxins damage cells of the liver, kidneys, and intestines. The symptoms progress through stages:
Central Nervous System Effects Mushrooms containing the compounds ibotenic acid and muscimol affect the central nervous system. The mushrooms most often involved in this type of poisoning are Amanita muscaria (fly agaric) and Amanita pantherina. Symptoms usually begin 30 minutes to 2 hours after ingestion (possibly earlier in cats) and include the following:
Muscarinic Reactions Muscarine is a substance that affects a specific metabolic pathway in cells of the body. Ingestion of muscarine-containing mushrooms—usually Clitocybe and Inocybe species—causes clinical signs related to part of the nervous system that regulates routine (not conscious) body functions. Symptoms appear a few minutes to a couple of hours after ingestion:
Hallucinations Hallucinogenic mushrooms include those in the genera Psilocybe, Conocybe, Panaeolus, Copelandia, Pluteus, and Gymnopilus. The toxic components are psilocybin and psilocin, which are similar to the drug lysergic acid diethylamide (LSD). Symptoms usually begin within an hour or two after ingestion:
Gastrointestinal Irritation Many mushrooms cause gastrointestinal (digestive tract) problems. The exact toxin in most of these mushrooms is not known. Some of the mushroom genera that cause this type of problem are Chlorophyllum (which often forms fairy rings on lawns), Omphalotus, and Scleroderma. Symptoms usually begin soon after ingestion and improve on their own within a few hours. Most symptoms are mild:
Diagnosis Diagnosing mushroom poisoning is difficult unless the animal is seen eating the mushroom or vomits up pieces of mushroom. Known access to wild mushrooms, compatible symptoms, and physical examination findings can put mushroom poisoning on the list of possibilities. Blood and urine tests are used to assess organ function in dogs with symptoms. Treatment Treatment depends on the symptoms and type of mushroom (if known). Animals exposed to the most toxic mushrooms need early and aggressive treatment to survive. Unfortunately, early treatment isn’t possible if the ingestion was not witnessed and symptoms don’t begin until several hours later. No antidote is available for mushroom poisoning. The best way to manage the risk is to prevent pets from eating wild mushrooms. References 1. Hovda LR. Unfriendly fungi: five groups of mushrooms toxic to pets. DVM 360. Published October 20, 2015.

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. Containment 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 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.[1] Fireworks Toxicity 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.[2] Lit fireworks and smoke are obviously a risk to animals’ eyes and skin. Keep your pets completely away from new and used fireworks:

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. Turkey breast 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:
Bread 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. Photo by Charles 🇵🇭 |
