Toxic foods for dogs and cats: a practical list and what to do if they eat them

Kitchen table with a list of foods dangerous for dogs and cats

Many everyday foods can cause serious problems in dogs and cats. Here’s a short list of the most common culprits and how to respond if you suspect ingestion. If in doubt or if symptoms appear, call your veterinarian promptly.

The usual suspects—and why they’re dangerous

Chocolate and cocoa: methylxanthines may cause vomiting, hyperactivity and, at high doses, arrhythmias/seizures.
Grapes and raisins: risk of acute kidney injury in some dogs.
Onion, garlic, leeks: can cause hemolytic anemia.
Xylitol (sugar‑free gum and sweets): hypoglycemia and liver failure.
Alcohol and caffeine: CNS depression/stimulation; dehydration.
Cooked bones: splintering with obstruction or perforation risk.

Warning signs

Vomiting, diarrhea, excessive drooling.
Tremors, weakness, incoordination.
Marked lethargy, sudden behavior changes.
Little or no urine (especially after grapes/raisins).

What to do if they might have eaten a toxic food

Remove access and don’t induce vomiting unless a vet instructs you to.
Call your vet and share details (what, how much, when).
Keep the label/package if available.
Observe and log symptoms and timing (it helps during the consult).

Practical prevention at home

Teach the family not to give “table scraps”.
Store snacks and baked goods out of reach.
Check ingredients on “sugar‑free” products.
Offer safe enrichment alternatives (kong‑style toys, sniffing mats).
