Can dogs eat tea?

Caution — caffeine risk

Small amounts of brewed tea aren't usually an emergency but tea contains caffeine. Tea leaves and teabags are more concentrated and can cause toxicity.

The full picture

Tea contains caffeine, theophylline, and theobromine — all in the methylxanthine family that dogs process poorly. A lick of milky tea isn't going to harm a medium or large dog, but a small dog drinking a cup, or any dog eating tea leaves or teabags, is a different matter. Black tea has the most caffeine, green tea a bit less, white tea less again, and herbal teas vary — chamomile and rooibos are caffeine-free, but yerba mate and matcha are highly caffeinated. A teabag eaten whole can also be a GI blockage risk in small dogs.

Risks to watch for

  • Caffeine and theobromine toxicity
  • Teabags can cause blockage if swallowed
  • Herbal teas vary wildly
  • Milky tea adds lactose

Safe portion size

Not recommended. A tiny lick of cooled milky tea rarely causes harm.
