Can Dogs Eat Coffee? No — Caffeine Is Toxic to Dogs

Coffee is one of the most consumed beverages in the world — but for dogs, even a small amount can be dangerous. Caffeine is toxic to dogs, and coffee is one of the most concentrated sources of caffeine in most homes. Here's what you need to know.

Is Coffee Safe for Dogs?

No — coffee is toxic to dogs. Caffeine is a methylxanthine compound (the same family as theobromine in chocolate) that dogs metabolize much more slowly than humans. This allows caffeine to build up to toxic levels in a dog's system even from relatively small exposures.

Sources of Caffeine to Keep Away from Dogs

• Coffee (brewed, instant, espresso, cold brew)
• Coffee grounds — highly concentrated and particularly dangerous
• Tea (especially black and green tea)
• Energy drinks
• Some sodas
• Caffeine pills or supplements
• Some medications
• Dark chocolate (contains both theobromine and caffeine)

Signs of Caffeine Toxicity in Dogs

Symptoms typically appear within 1 to 2 hours of ingestion:

• Restlessness and hyperactivity
• Rapid breathing
• Elevated heart rate and blood pressure
• Muscle tremors
• Vomiting
• Seizures
• Collapse in severe cases

How Much Caffeine Is Toxic to Dogs?

The toxic dose is approximately 140mg of caffeine per kilogram of body weight, but symptoms can appear at much lower doses. A single cup of brewed coffee contains 80 to 100mg of caffeine — enough to cause symptoms in a small dog. Coffee grounds are far more concentrated and extremely dangerous even in small amounts.

What to Do If Your Dog Drinks Coffee

1. Act immediately — do not wait for symptoms
2. Call your vet or ASPCA Animal Poison Control: (888) 426-4435
3. Note the type and amount consumed and your dog's weight
4. Get to an emergency vet if directed

Keep the EBPP Dog Feeding Chart Fridge Magnet on your refrigerator as a quick reference — and make sure everyone in the household knows to keep coffee and coffee grounds completely out of the dog's reach.

Final Thoughts

Coffee and all caffeine-containing products are toxic to dogs. Keep coffee cups, pods, grounds, and beans completely out of reach. If your dog ingests any amount of caffeine, treat it as an emergency and contact your vet immediately.
