Can My Dog Drink Coffee?
No - dogs should not have coffee. Caffeine is toxic to dogs, and they are far more sensitive to it than people. A stray lick of brewed coffee usually is not enough to poison a dog, but coffee beans, grounds, tea bags and caffeine pills are highly concentrated and dangerous, and can be fatal for small dogs. Signs include restlessness, a racing heart, vomiting, tremors and seizures. If your dog ingests caffeine, call your vet immediately.
No - dogs should never drink coffee or have caffeine. Caffeine is toxic to dogs, and because they’re much more sensitive to it than we are, amounts that seem trivial to a person can make a dog seriously ill. There is no safe serving of coffee for a dog.
How bad is it, really?
It depends on what and how much:
- A stray lick or two of brewed coffee usually isn’t enough to poison most dogs - but it should never be offered on purpose.
- Coffee beans, ground coffee, tea bags, energy drinks and caffeine pills are the real danger - they’re highly concentrated. For a small dog, even one or two caffeine pills can be fatal.
The stimulant in coffee (caffeine, a “methylxanthine,” the same family as the theobromine in chocolate) overstimulates a dog’s heart and nervous system.
Signs of caffeine poisoning
Symptoms usually appear within 30–60 minutes and can last many hours:
- Restlessness, hyperactivity, pacing and jitteriness
- Excessive vocalising
- Rapid heart rate and abnormal heart rhythm
- Vomiting and diarrhoea
- High blood pressure and raised temperature
- Tremors, and in severe cases seizures or collapse
What to do if your dog gets caffeine
Treat it as an emergency, especially with beans, grounds or pills:
- Note what was eaten, roughly how much, and when.
- Call your vet or an emergency animal hospital immediately.
- Or contact a pet poison helpline - Pet Poison Helpline: (855) 764-7661 or ASPCA Animal Poison Control: (888) 426-4435 (fees may apply).
- Don’t wait for symptoms, and don’t induce vomiting unless told to.
The good news: with prompt treatment (decontamination and supportive care), most dogs recover well.
Keep caffeine out of reach
- Don’t leave mugs of coffee or tea where a dog can reach them.
- Dispose of used coffee grounds and tea bags in a secured bin - dogs are often attracted to them.
- Store beans, pills, pre-workout powders and energy drinks well out of reach.
Give your dog fresh water - that’s the only drink they need.
