Can Dogs Drink Coffee or Tea?

Verdict: TOXIC — never give dogs coffee, tea or any caffeinated drink.

Caffeine is a methylxanthine, the same family of compounds that makes chocolate dangerous. Dogs metabolize caffeine very slowly, so it builds up quickly in their system. Coffee, tea, energy drinks, soda and even coffee grounds or tea bags are all dangerous.

Why it's dangerous

Caffeine stimulates the nervous system and heart. The darker or stronger the brew, the higher the caffeine — and the higher the risk. Espresso, cold brew and energy drinks are the most concentrated.

Symptoms of caffeine poisoning

• Vomiting and diarrhea
• Restlessness, hyperactivity
• Panting, excessive thirst and urination
• Rapid or abnormal heart rhythm
• Tremors, seizures
• In severe cases: collapse and death

Symptoms usually appear within 1-2 hours of ingestion.

How much is dangerous?

There is no safe amount. Even a few sips of strong coffee can cause symptoms in a small dog. Coffee grounds and tea bags are especially dangerous — a dog that eats them gets a concentrated dose.

What to do if your dog drinks coffee

1. Note how much and how strong, and your dog's weight.
2. Call your veterinarian or ASPCA Poison Control (888) 426-4435 immediately.
3. Do not induce vomiting unless your vet tells you to.
4. Severe cases need hospitalization, IV fluids and heart monitoring.
