Can dogs drink tea?

Dogs are part of our families and we like to share many of life’s pleasures with them. But should that include a brew?

Many of us love a good cup of tea—whether it’s for the flavour, the comforting ritual, or the energising lift from its caffeine. That little boost helps us wake up, focus, or recharge on a busy day. But while tea is a favourite pick-me-up for people, is it safe to share with our dogs? 

Is tea bad for dogs?

Tea contains caffeine, which dogs can’t process well. While a small amount of caffeine helps wake us up, it can harm dogs. Dogs are highly sensitive to caffeine, which can quickly reach toxic levels in their systems. Drinking tea could cause symptoms like vomiting, restlessness, a high heart rate and in severe cases, coma or even death. Dogs have no need for caffeine in their diets, so it’s safest to avoid giving them tea altogether.

Is caffeine bad for dogs?

Yes, caffeine can be dangerous for dogs. Unlike humans, dogs metabolise caffeine slowly, meaning it stays in their system longer. Just a small amount can overstimulate their nervous and cardiovascular systems. Caffeine poisoning can cause symptoms within one to two hours, including:

  • Rapid breathing
  • Muscle tremors
  • Increased blood pressure
  • Seizures

If your dog accidentally consumes tea, coffee, or any caffeinated item, contact a vet immediately. It’s a risk not worth taking.

Can dogs drink decaffeinated tea?

While decaffeinated tea has less caffeine, it’s still not ideal for dogs. Decaffeinated tea contains tannins, which are chemicals that can harm dogs. High tannin levels may lead to liver or kidney damage, which could cause serious long-term health problems.

Is tea with milk safe for dogs?

Adding milk doesn’t make tea any safer for dogs. In fact, many dogs are lactose intolerant, and milk could cause an upset stomach, diarrhoea, or gas. Milk also won’t remove any caffeine or tannins in the tea. Stick to dog-safe treats rather than milk tea for your pet.

Green tea for dogs

Green tea has less caffeine than black tea but still contains enough to be potentially harmful to dogs. Green tea also contains tannins, which can still be damaging over time. The risks of caffeine and tannins outweigh any potential health benefits green tea might offer.

Are herbal teas safe for dogs?

Most herbal teas don’t contain caffeine, which makes them a better option in some cases. However, many herbs can be toxic to dogs, and each blend can vary greatly in ingredients. For example, some herbal teas contain certain plants or additives that can upset a dog’s stomach or lead to more serious issues. Always research specific ingredients and ask a vet before giving your dog any herbal teas.

Calming tea for dogs

If you’re interested in using tea to calm your dog, there are specific pet-safe herbal options. Some pet stores and vet clinics offer specially formulated “calming teas” for dogs, which are safe and free of harmful ingredients. These can be helpful for anxious dogs, but always check with your vet first.

Chamomile tea for dogs

Chamomile is one herbal tea that some vets recommend in very small doses for upset stomachs or relaxation. However, it’s essential to use it sparingly and always dilute it well. Chamomile can interact with certain medications, so consult a vet before using it.

Peppermint tea for dogs

Peppermint tea, when properly diluted, can also be helpful for mild digestive issues. However, too much peppermint can be irritating and isn’t suitable for every dog. Never offer concentrated peppermint or peppermint-flavoured foods, as they may contain other harmful additives.

Alternatives to tea for dogs

There are plenty of other dog-safe ways to provide comfort and relaxation without the risks associated with tea. Consider trying:

  • Bone broths: These are tasty, soothing, and packed with nutrients.
  • Fresh water: Keep their water bowl filled for hydration without the risks.
  • Specialty pet drinks: Look for dog-friendly drinks available at pet stores.
