Our pets are at our mercy, so it’s up to us to make sure they’re safe. This can be tough sometimes, because a lot of seemingly harmless everyday foods can be toxic to our animals—especially dogs, who can’t tell the difference between a tasty snack and a one-way ticket to the emergency vet.

Your best bet is probably to assume that any human food has the potential to be hazardous to your pet, but this graphic from the Bark is a handy guide for the most common foods they might encounter:

An illustrated infographic titled "The World's Most Dangerous Foods for Dogs." It includes: Alcohol (coma, death, intoxication), avocado (contains persin: vomiting, diarrhea), raisins and currants (kidney failure), cooked bones (stomach lacerations), walnuts and macadamias (nervous system and muscle damage), too much onions and garlic (blood cell damage, anemia), too much dairy (diarrhea), grapes (kidney failure), some varieties of mushrooms (shock death), too much fatty foods (pancreatitis), caffeine (vomiting, diarrhea, toxic to heart & nervous system), xylitol in gum, candy (liver failure, hypoglycemia, death), chocolate (toxic to heart & nervous system, death), medications like Tylenol and Advil (kidney failure, GI ulcers). If you think your dog ate something dangerous, call your vet or the ASPCA Poison Control Hotline (888) 426-4435 or the National Pet Poison Helpline (800) 213-6680.

Some of these are pretty surprising. For example, grapes (and raisins) seem harmless enough, and your dog might scarf them right up—but unfortunately, both fresh and dried grapes can cause acute kidney failure. Onions and garlic can be toxic to dogs too, triggering blood cell damage or even anemia when consumed in high quantities.

This graphic doesn’t cover every single potentially dangerous human food that a dog might encounter. For a full list of foods, plants, medicines and more that are poisonous to pets, check out this database from the Pet Poison hotline. It lets you search foods, medications, household chemicals, and other potential poisons by name, and tells you how dangerous an exposure is for different kinds of pets.

Hopefully, you’ll never need the Pet Poison database, but if your dog does ingest something they shouldn’t, it can help you figure out how serious the situation is. Your family vet should always be your first call, but for pet poison-specific questions, there are two national helplines you can call any time:

ASPCA Pet Poison Control Hotline: (888) 426-4435

National Pet Poison Helpline: (800) 233-6680
