Can dogs eat caffeine?
No, dogs should not have coffee, tea, energy drinks, coffee grounds, or caffeine pills. Caffeine can cause restlessness, vomiting, a racing heart, tremors, or seizures. Grounds and pills are a same-hour poison-hotline call, so bring the container.
Portion and preparation
None. Coffee, tea, energy drinks, coffee grounds, and caffeine pills are all sources; there is no safe home portion in ounces (grams), and a smaller pet can be harmed by less than a larger one. Powder, broth, and baked goods count the same as the plain ingredient.
Why this matters chemically
Caffeine is a methylxanthine, like theobromine in chocolate, and dogs and cats clear it slowly. Coffee, tea, energy drinks, grounds, and pills all count, and a spoon of grounds can matter more than a sip of milky coffee. Keep the package where pets cannot reach it.
What clinical signs can appear?
Signs vary with the amount eaten, the animal's weight in pounds (kilograms), and how much time has passed. The list below is what clinics commonly ask about. It is not a checklist that rules disease in or out for one animal.
- Restlessness
- Vomiting
- Fast heart rate
- Tremors or seizures
What if this was eaten?
Call poison control the same hour, especially after grounds, espresso, or a pill. Take the product away; do not induce vomiting at home; bring the container; bring the package and the pet's weight in pounds (kilograms) when you call. Do not induce vomiting unless a veterinarian or poison specialist tells you to.
Which agencies regulate this advice?
The FDA regulates pet food and animal drugs in the United States. The VMD licenses veterinary medicines in the United Kingdom, where DEFRA also sets animal-health rules, and the APVMA registers veterinary chemical products in Australia.
