Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Most caffeinated teas (black, green, oolong) contain caffeine and theobromine, both of which are toxic to dogs in sufficient quantities. Symptoms of caffeine toxicity include restlessness, rapid breathing, heart palpitations, muscle tremors, and seizures. However, small amounts of cooled, diluted chamomile or peppermint herbal tea (which are naturally caffeine-free) are generally considered safe and may even soothe mild stomach upset. Never add milk, sugar, or sweeteners — especially xylitol, which is extremely toxic. If your dog accidentally drinks caffeinated tea, monitor closely and contact your vet if symptoms appear.
What You Should Know
While tea is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
