Many dog owners love sipping a warm cup of tea and often wonder, “Can dogs drink tea too?” The idea might sound harmless, especially since tea is natural and full of antioxidants. However, what’s safe for humans isn’t always safe for dogs. Before sharing a sip from your mug, it’s essential to understand how tea affects canine health, what risks it poses, and whether there are any dog-friendly alternatives.
In this complete guide, we’ll explore everything dog owners need to know about tea — including types of tea, potential benefits, dangers, and safer substitutes for your furry friend.
Understanding What’s Inside Tea
Tea, whether black, green, white, or herbal, contains compounds that can affect your dog’s body differently than yours. The main ingredient of concern is caffeine. Even small amounts of caffeine can overstimulate your dog’s nervous system, causing restlessness, increased heart rate, and other serious health problems.
According to Purina, caffeine is one of the most common toxic substances for dogs, and the amount present in tea is enough to cause negative reactions depending on the dog’s size and tolerance.
Besides caffeine, tea also contains theobromine, an alkaloid similar to the compound found in chocolate, which dogs cannot metabolize efficiently. This combination can lead to toxicity, especially if tea is consumed regularly.
Can Dogs Drink Black or Green Tea?
Many people assume green tea is healthy for everyone because of its antioxidants and natural properties. However, for dogs, the situation is different. Black tea and green tea both contain caffeine, and even though the levels vary, both can be harmful.
As highlighted by KC Insurance, caffeinated drinks such as black and green tea are unsafe for pets. Symptoms of caffeine toxicity include:
- Increased heart rate
- Tremors or shaking
- Vomiting
- Diarrhea
- Restlessness
- Elevated blood pressure
If your dog consumes tea accidentally, the severity of the symptoms depends on the amount consumed and the dog’s size. Small breeds are more at risk because their bodies cannot process caffeine as efficiently.
What About Herbal Teas?
Herbal teas are often caffeine-free, which makes them seem like a safer alternative. But not all herbal teas are safe for dogs either. Some herbal blends contain ingredients such as chamomile, hibiscus, or peppermint, which can be soothing in moderation, while others may include toxic herbs like tea tree, pennyroyal, or comfrey, which are dangerous for pets.
As explained by Felcana, small amounts of caffeine-free herbal teas like chamomile or rooibos can sometimes help with relaxation or digestion — but only if given occasionally and approved by a vet.
Therefore, it’s crucial to read every ingredient before offering herbal tea to your dog and consult your veterinarian beforehand.
Why Caffeine Is Dangerous for Dogs
Caffeine is a central nervous system stimulant, and dogs are far more sensitive to it than humans. Even a few sips of strong tea can raise your dog’s heart rate and cause hyperactivity or anxiety.
Theobromine and caffeine work together to increase blood pressure and overstimulate your dog’s system. Prolonged exposure or large doses may even lead to cardiac arrhythmia, seizures, or collapse.
For context, toxic caffeine levels for dogs start at about 9 mg per pound of body weight, and some teas can contain over 30 mg per cup. That means even a single cup could cause symptoms in small or medium dogs.
What Happens If a Dog Drinks Tea?
If your dog accidentally drinks a small amount of tea, don’t panic — a lick or two may not cause harm. However, monitor closely for the following signs:
- Restlessness or pacing
- Rapid heartbeat
- Panting
- Vomiting or diarrhea
- Muscle tremors
- Seizures (in severe cases)
If any of these symptoms appear, contact your veterinarian immediately. Quick action can prevent serious complications.
Are There Any Benefits to Giving Dogs Tea?
Although caffeine-based teas should be avoided, some herbal teas can be beneficial if served correctly and in moderation. For example:
- Chamomile tea (unsweetened and caffeine-free) can soothe an upset stomach and calm anxiety.
- Rooibos tea is antioxidant-rich and may help with skin irritation.
- Ginger tea (mildly brewed) can aid digestion or reduce nausea.
But remember: even safe teas must be given without sugar, milk, or lemon, all of which can irritate a dog’s stomach or cause allergies.

Can Puppies Drink Tea?
Puppies should never drink tea. Their digestive systems are still developing, and caffeine or strong herbal ingredients can quickly upset their balance. Puppies require hydration through fresh, clean water and proper puppy-formulated nutrition only.
In fact, tea may reduce their appetite and interfere with calcium absorption, potentially harming growth. If you want to treat your puppy, stick to vet-approved puppy milk replacers instead. You can learn more about milk safety in our post Can Dogs Drink Almond Milk?.
Homemade Herbal Tea Alternatives (Dog-Friendly Options)
If you’d like to share a cozy moment with your dog during tea time, there are safe, caffeine-free herbal infusions you can prepare at home:
- Chamomile and Honey Brew – Boil water, steep chamomile flowers, and cool it completely before serving a tablespoon or two. Helps with mild anxiety.
- Rooibos Tea – Naturally sweet and caffeine-free, rich in antioxidants and gentle on digestion.
- Ginger Water – A few slices of ginger in boiled water can soothe motion sickness or mild nausea.
- Mint Infusion – Helps with bad breath, but should be mild and unsweetened.
Always serve cooled tea and never replace your dog’s main hydration source — water should always come first.
How to Respond If Your Dog Drinks Tea Accidentally
If your dog manages to drink tea unattended, follow these steps immediately:
- Check the label – Identify the type of tea and whether it contains caffeine.
- Estimate the amount – Determine how much your dog might have consumed.
- Call your veterinarian – Even if symptoms aren’t visible, a professional should guide you.
- Watch for signs of distress – Restlessness, shaking, vomiting, or rapid breathing require urgent attention.
The sooner you act, the better the chances your dog will recover without complications.

Expert Opinion: What Veterinarians Say
Veterinary experts agree that dogs should not drink caffeinated tea due to their sensitivity to caffeine and theobromine. Occasionally, caffeine-free herbal teas may be acceptable, but only under professional supervision.
As noted in Purina’s pet care article, even tiny amounts of caffeine can overstimulate a dog’s heart and nervous system. Therefore, it’s safer to keep your dog away from any beverage made for humans.

Conclusion
So, can dogs drink tea? The safest and simplest answer is no — they shouldn’t. While tea offers benefits to humans, it can be risky for dogs due to caffeine, additives, and certain herbs. Occasional use of caffeine-free herbal teas like chamomile or rooibos might be fine under veterinary guidance, but plain water remains the healthiest choice.
Your dog’s well-being depends on providing the right nutrition and avoiding human foods or drinks that can cause harm. Always research before offering something new and consult your vet for personalized advice.
By making informed decisions, you ensure your furry companion enjoys a safe, energetic, and happy life — without a drop of caffeine in sight.
