Can dogs eat
Coffee?
No
No. Coffee, coffee grounds and coffee beans contain caffeine, which is toxic to dogs. A lick of spilled coffee is unlikely to poison most dogs, but grounds, beans and a real drink can, so call your vet if your dog got into any.
Why it’s unsafe
Caffeine belongs to the methylxanthines, the same family of stimulants as the theobromine in chocolate. The ASPCA names these compounds as the source of toxicity, and the Merck Veterinary Manual lists caffeine as one of the two main toxic agents in chocolate poisoning in dogs. The more concentrated the caffeine, the greater the danger. Pet Poison Helpline says coffee grounds and beans can cause severe poisoning because of their high concentration of caffeine, and that coffee filters are harmful too.
According to the AKC, dogs react more strongly to caffeine than people do. A lick or two of coffee is unlikely to poison most dogs, but grounds, beans and tea bags are a much bigger threat. Small dogs are affected more than large ones. Caffeine overstimulates the body, and Pet Poison Helpline lists a raised heart rate, agitation, rising blood pressure, irregular heart rhythms, tremors and convulsions among the effects. In severe cases collapse and death can occur, but the AKC says most dogs survive when they get help quickly.
Risks
- Caffeine is a stimulant that can raise heart rate and blood pressure and cause irregular heart rhythms
- Grounds, beans and filters are the most concentrated and most dangerous forms
- Signs include restlessness, vomiting, panting, tremors and seizures, and severe poisoning can be fatal
- Small dogs are affected more than large dogs
- Caffeine is also in tea, energy drinks, soda, diet pills and chocolate
What to give instead
Do not offer coffee in any form. Keep mugs, pods, grounds, beans, filters and tea bags out of reach, secure the trash, and remind guests and family. The AKC also recommends teaching a reliable "leave it."
For a drink, fresh water is all your dog needs. If you want to share a snack while you sip your coffee, offer a few plain carrot pieces instead.
Related forms
| Food | Verdict | Why |
|---|---|---|
| Brewed coffee | No | A stray lick is unlikely to poison most dogs, but never offer it. |
| Coffee grounds, beans and filters | No | Highest in caffeine and the most dangerous forms. |
| Tea and tea bags | No | Also contain caffeine; tea bags are more dangerous than a lick of tea. |
| Energy drinks and soda | No | Pet Poison Helpline lists energy drinks and soda among caffeine sources. |
| Chocolate-covered espresso beans | No | Caffeine plus chocolate; see our page on chocolate. |
If your dog already ate it
Call your vet right away. If you cannot reach them, call Pet Poison Helpline at (855) 764-7661 or ASPCA Animal Poison Control at (888) 426-4435 (US; fees may apply), or go to an emergency clinic. Have your dog's weight and a best guess of what and how much was eaten ready.
The AKC says signs can appear within 30 to 60 minutes, and Pet Poison Helpline says usually 1 to 2 hours. Watch for agitation, pacing, panting, vomiting, a racing heart, tremors or seizures. Effects can last from 12 hours to several days. Do not make your dog vomit at home; a vet may decide to do so or may give activated charcoal, fluids and medicine for the heart and seizures. If your dog only licked a little spilled coffee, call anyway if you are unsure, and monitor closely.
Frequently asked questions
How much coffee is toxic to dogs?
It depends on the form, the amount and your dog's size, and no source gives a safe amount. Grounds and beans are far more concentrated than brewed coffee: Pet Poison Helpline says three teaspoons of instant coffee grounds would be enough to cause moderate signs in a medium-sized dog. Call your vet with your dog's weight and the amount.
My dog licked spilled coffee. Should I worry?
The AKC says a lick or two is unlikely to poison most dogs, though it could still make your dog sick. Watch for restlessness, panting, vomiting or tremors, and call your vet if you see them or you are unsure.
How long does caffeine poisoning last in dogs?
The AKC and Pet Poison Helpline say effects can last from about 12 hours to several days, and recovery is likely if a dog reaches a vet in time.
Is coffee as dangerous as chocolate for dogs?
Both contain methylxanthines, which the ASPCA names as the toxic agents. Chocolate also has theobromine. Coffee grounds and beans can also cause serious poisoning.
