Human foods that are toxic to dogs and cats
Some of the most dangerous foods for pets are ordinary kitchen staples — not exotic ingredients you'd never have on hand. Here's what actually belongs on the list.
The well-known dangers
Chocolate (darker is more toxic), grapes and raisins (dangerous even in small amounts, with a toxic mechanism still not fully understood), onions and garlic (damage red blood cells over time, not just from a single large dose), and xylitol (an artificial sweetener in sugar-free gum and some peanut butters, extremely dangerous even in tiny amounts) are the ones most owners have heard of, for good reason.
The ones that surprise people
Macadamia nuts, alcohol in any form, raw yeast dough (expands and produces alcohol as it rises inside the stomach), avocado (in large quantities, more of a concern for birds and some other species but worth avoiding), and excessive salt or fatty table scraps that can trigger pancreatitis are all less well-known but genuinely dangerous.
If you suspect ingestion
Contact a vet or a pet poison control hotline immediately rather than waiting to see if symptoms appear — for several of these (grapes, xylitol especially), treatment is far more effective before symptoms start than after. Don't induce vomiting unless a professional specifically tells you to; it's the wrong response for some toxins and can make things worse.
Our dog and cat nutrition basics guides cover what should be in the bowl, not just what shouldn't. If your pet has already eaten something on this list, our poison control contact card and emergency checker tools are the faster next step.
