Can Dogs Eat Tea?

TOXIC

NO — Caffeinated tea (black, green, oolong) is toxic to dogs because of caffeine.

Tea leaves and tea bags concentrate caffeine and can cause serious toxicity. This page covers tea from the Camellia sinensis plant only.

If your dog has already eaten tea, contact your veterinarian or an animal poison control service straight away — even if your dog seems fine.

See our guide to common toxic foods for dogs for the wider picture.

The full answer

Tea made from the Camellia sinensis plant — including black, green and oolong tea — contains caffeine. Caffeine belongs to the methylxanthines, the same group of stimulants involved in chocolate poisoning in dogs.

Pet Poison Helpline notes that one or two licks of tea are unlikely to cause poisoning, but tea bags and loose tea leaves contain much more caffeine and could cause serious toxicity.

Not every drink called "tea" is covered here. Herbal teas and decaffeinated tea are not covered by this page's rating, and tea tree oil is a different substance altogether.

Risks and Things to Know

  • Signs reported with caffeine toxicity include restlessness and hyperactivity, digestive upset, increased heart rate, heart-rhythm and blood-pressure changes, and neurological signs.
  • Tea bags, loose leaves and tea-based products concentrate caffeine.

How Much Can Dogs Eat?

Do not give tea to dogs.

How Should I Prepare It?

  • Not applicable. Store tea bags and loose tea out of reach, and dispose of used bags where your dog can't get them.

What If My Dog Ate Too Much?

If your dog has eaten tea bags or loose tea leaves, or shows restlessness, a racing heart or other unusual signs after tea, contact a veterinarian or an emergency veterinary clinic straight away.
