As pet parents, it’s often tempting to share our favorite snacks with our furry friends—but some human foods can be quite harmful, even toxic, to dogs and cats. And, of course, sometimes our pets get into food unintentionally. Knowing what foods to avoid helps keep your pets safe and healthy.
----Common Foods to Keep Away from Pets----
Grapes and Raisins – Even small amounts can cause kidney failure in dogs and even brain damage has been documented. The toxic principle is tartaric acid (yes, avoid cream of tartar also) and the amount varies markedly in grapes and raisins. The risk is huge, so grapes and raisins should just be avoided entirely.
Xylitol (found in sugar-free gum, candy, peanut butter, tooth pastes and a large number of food products) – Can cause a dangerous drop in blood sugar and life-threatening liver failure in dogs. This is one of the most hazardous food items, and it is quietly present in a large variety of food products.
Chocolate – Contains theobromine and caffeine, which can cause vomiting, diarrhea, tremors, seizures and even death. The severity of the danger depends on the type and amount of chocolate and the size of the pet. Dark chocolate is especially dangerous due to higher theobromine levels.
Alcohol and Caffeine – Both can be life-threatening, even in relatively small amounts. Ingestion of yeast dough can lead to alcohol toxicity also.
Onions, Garlic, Chives – These can damage red blood cells, leading to anemia, A tiny amount isn’t usually harmful, but none at all is the safest bet.
Bones and Fatty Foods – Bones can splinter and cause internal injuries such as bowel perforation while fatty foods may lead to pancreatitis.
Dairy – Many pets are simply lactose intolerant, leading to stomach upset. Not truly poisonous, but it can make them sick.
Safe Alternatives
Instead of an array of human foods, try pet-safe treats like small pieces of cooked chicken (no skin), carrots, green beans, or store-bought treats made just for pets.
When in Doubt
If your pet eats something they shouldn’t, call your veterinarian right away or contact the ASPCA Animal Poison Control Center.
👉 Bottom line: Our pets rely on us to make safe choices for them and protect them from their own indiscriminate “grazing”. Sticking to pet-approved foods and treats is the best way to prevent food-related illness. And if you have a “counter-surfer”, be aware of the more dangerous food products to help prevent accidental poisoning.
