Why

Coffee, grounds and beans are concentrated caffeine — a methylxanthine, the same family as chocolate's theobromine. It causes hyperactivity, vomiting, a racing or abnormal heart rhythm, tremors and seizures. Used grounds in the trash still contain caffeine.

Signs to watch for if your dog has eaten coffee

Vomiting and diarrhea
Restlessness, hyperactivity or pacing
Panting, excessive thirst and urination
A fast or irregular heartbeat
Muscle tremors or seizures

Signs can lag by a day or more, so no symptoms does not mean your dog is clear — call rather than watch.

What to do now

Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 straight away. Tell them what your dog ate, roughly how much, and when, and take the packaging with you. Don't wait for symptoms — with several poisons the harm is done before a pet looks ill.

Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.

Safer alternatives for dogs

Plain baby carrots or carrot sticks
Plain cooked chicken breast — no skin, no bones, no seasoning
A few blueberries or a slice of apple with the core removed
Plain canned pumpkin (not pie filling)
Plain green beans, fresh or frozen
