Is It Safe for Dogs to Drink Tea?

Dogs should not drink regular tea, especially not black or green tea that contains caffeine. While a few licks from your mug won’t harm most dogs, regularly giving tea — particularly if it’s caffeinated, sweetened, or contains milk — is not recommended.

Caffeine, in particular, can be toxic to dogs in large amounts, and many teas also include ingredients that upset a dog’s stomach.

Why Is Tea Bad for Dogs?

1. Caffeine Content

Most traditional teas — including English breakfast, Earl Grey, green, and oolong — contain caffeine, which affects dogs much more strongly than humans. Even small amounts can lead to:

• Restlessness

• Increased heart rate

• Vomiting or diarrhoea

• Muscle tremors

• In severe cases, seizures or collapse

2. Milk and Sugar

Many people drink tea with milk or sugar. Dogs are often lactose intolerant, and sugar adds unnecessary calories. Sweeteners like xylitol, sometimes found in sugar-free syrups or sweetened drinks, are extremely toxic to dogs.

3. Herbal Tea Risks

Some herbal teas — like chamomile or peppermint — may be safe in tiny amounts or under vet guidance, but others, like tea tree or some detox blends, can be dangerous. Always check ingredients carefully.

What If My Dog Drank a Bit of Tea?

If your dog only had a small amount of weak tea, or licked the inside of your mug, they’re unlikely to be harmed. But if they’ve drunk a full cup, especially one containing caffeine or artificial sweeteners, it’s worth contacting your vet for advice — particularly for small breeds or puppies, who are more sensitive.

Watch for symptoms such as hyperactivity, vomiting, shaking, or unusual behaviour.

Healthier Alternatives for Dogs

Your dog doesn’t need tea — their best drink is always fresh, clean water. However, if you want to give them a bit of variety, safe options include:

• Low-sodium chicken or beef broth (as a treat)

• Ice cubes made with water and a splash of broth

• Dog-safe herbal infusions, like cooled chamomile tea (vet-approved only)

These are best given occasionally, not as a replacement for water.

Final Thought

Dogs should not drink tea, especially if it contains caffeine, sugar, or milk. While a tiny sip isn’t likely to be harmful, making tea a regular part of your dog’s diet is a bad idea. Stick to water, and if you want to treat them, try vet-approved alternatives that support their health — not compromise it.
