Foods To Avoid Giving Your Dog

Foods to Avoid Giving Your Dog

September is National Food Safety Month. Like cats and humans, certain foods can be toxic to dogs. While cats and dogs share many food toxicities, here is dog-specific and alphabetic list of the foods you should avoid giving your dog. 

Alcohol: Dogs are far more sensitive to alcohol than humans are. Just a little bit can cause vomiting, diarrhea, central nervous system depression, coordination problems, difficulty breathing, coma, and even death. Hops in particular, which is found in beer, has been found to poison dogs. Dogs affected by hops can have damage and failure to multiple organ systems due to an uncontrollably high body temperature. 

Avocado: Persin, the toxic element in Avocado, can cause mild upset stomach. Persin can be found in the leaves, seed, bark, and inside the fruit. Avocado is sometimes included in pet food but does not pose a threat to dogs. 

Chocolate: Unlike cats, dogs will eat chocolate on their own. The rule with chocolate is usually, “the darker the chocolate, the more dangerous it is.” White chocolate contains very few methylxanthines, the toxic component of chocolate, while dark baker’s chocolate has very high levels of methylxanthines. Depending on the type and quantity of the chocolate consumed, the reaction your dog may have can range from vomiting, increased thirst, abdominal discomfort, and restlessness to severe agitation, muscle tremors, irregular heart rhythm, high body temperature, seizures, and death. 

Coffee/Caffeine: Caffeine in large enough quantities can be fatal for a dog and there is no antidote. Symptoms of caffeine poisoning include restlessness, rapid breathing, heart palpitations, muscle tremors, and bleeding. 

Corncobs: Corncobs are not digestible and often cause obstructions in the intestines. 

Fat Trimmings and Bones: Don’t feed your dog table scraps. Fat, when cooked or uncooked, can cause pancreatitis (inflamed pancreas). Bones should not be given to dogs either, as they can choke on it or the bone may splinter and cause an obstruction or internal lacerations. 

Grapes and Raisins: Although it is not known what makes grapes and raisins toxic, they have been associated with kidney failure in dogs. Some dogs eat them without any effects while others can develop vomiting, lethargy, diarrhea, and kidney failure. Kidney failure means your dog’s ability to product urine decreases so they are unable to filter toxins out of their system. 

Macadamia nuts: Although the chance that macadamia nuts are deathly to dogs is low, the symptoms they do feel can be very uncomfortable. Symptoms can include muscle tremors, paralysis of the back legs, vomiting, and more. 

Milk/Dairy Products: Because dogs are devoid of the lactase needed to breakdown milk, milk and milk-based products can cause diarrhea and an upset stomach. 

Mushrooms: Some types of mushrooms contain toxins that can affect multiple systems in the body that result in nervous system abnormalities, seizures, shock, or death. 

Onions, Garlic, and Chives: All members, and close members of the onion family (including shallots, garlic, scallions, etc.), can cause damage to a dog’s red blood cells, leading to anemia. Like chocolate, the stronger it is, the more toxic it is. Garlic has been found to be more toxic to dogs than onions. Even dehydrated forms of garlic and onion are a threat to your dog’s health. Affected dogs may exhibit symptoms up to five days later and can include weakness, reluctance to move, and orange-tinted to dark red urine. Dogs that have ingested garlic or onion should be examined by a veterinarian immediately. 

Persimmons, Peaches, and Plums: The seeds or pits from these fruits are the main concern. Persimmons seeds can cause inflammation of the small intestines or intestinal obstruction. Intestinal obstruction is also a concern for peach and plum pits. Peach and plum pits also contain cyanide which is poisonous to both dogs and humans. Humans just know not to eat them. 

Raw eggs, meat, and fish: Raw eggs, meat, and fish can contain bacteria like salmonella that can lead to food poisoning. Raw eggs also interfere with the absorption of biotin (a B vitamin) and can lead to skin, hair, and coat issues. Certain fish can cause “fish disease” which can be fatal within the first two weeks. The first signs are vomiting, fever, and swollen lymph nodes. Thoroughly cooking meat and fish will kill the parasites and protect your dog. 

Salt: Giving your dog salty foods is not a good idea. Eating too much salt can cause excessive thirst and urination which leads to sodium ion poisoning. Symptoms of excessive salt consumption can include vomiting, diarrhea, depression, elevated body temperature, seizures, and even death. 

Sugary foods: Sugary foods, such as candy and gum, are usually sweetened with xylitol. Xylitol is known for increasing insulin production which causes blood sugar levels to drop. It can also cause disorientation and seizures as fast as 30 minutes after ingestion or as delayed as several hours. Xylitol can also lead to liver failure in just a few days. Even if the sugary food doesn’t contain xylitol it can still lead to obesity, dental problems, and diabetes. 

Yeast dough: Yeast dough can expand and produce gas in the digestive system. This can lead to pain and a possible rupture of the stomach or intestines. Additionally, when the yeast causes the dough to rise, it produces alcohol that can lead to alcohol poisoning. Dogs with extreme poisoning cases can go into a coma or have seizures. 

Non-food items: Foreign objects such as toys, small items of clothing, and medicine are perhaps a greater risk to dogs than food. One case is medical marijuana. It comes in many forms that a pet can easily eat and can cause vomiting, changes in heart rate, and depress the nervous system. If you suspect your dog ate any of these foods, first try to determine what and how much he or she ate. You should then call us or your veterinarian to see if medical attention is needed. If a veterinarian is not available, call either Animal Poison Control at 888-426-4435 or the Pet Poison Helpline at 800-213-6680. Do you have a cat? Most foods that are toxic for dogs are also toxic for cats. Check out this blog post for a cat-specific list of toxic foods. If you’re unsure about a certain food for either your cat or your dog and it’s not on this list, call your veterinarian. Your pet’s health is worth the call!
