Can Dogs Drink Green Tea? By PetWell

Can Dogs Drink Green Tea?


Can dogs drink green tea? Yes, dosed correctly, green tea is good for dogs and cats. Just as it is for humans.

There are decaffeinated options available.  Caffeine-free versions of both natural green tea and green tea extracts/concentrate are OK for dogs on a regular basis.

Unlike green tea, black tea is oxidised longer. The process of oxidisation reduces levels of catechins (natural polyphenolic phytochemicals), found in green tea leaves. It’s the catechins in green tea that makes it a powerhouse of antioxidants.  

Green tea contains caffeine, which is not ideal for pets, so the dosage must be correct.  

The antioxidant properties in green tea fight cancer cells. Also reducing inflammation of the liver and gastrointestinal tract. Along with boosting the immune system to help fight off infections and any condition calling for the use of antioxidants. 

If your pet is suffering with stress and anxiety, try PetWell CALM Anxiety Aid, that contains green tea along  with other calming and restorative ingredients.

What are the benefits of green tea for my pet?

The standout benefits of green tea for dogs and cats are;

Catechins - epigallocatechin-3-gallate (EGCG)

Green tea retains a significant level catechins due to minimal oxidation. The primary active catechin found in green tea is epigallocatechin-3-gallate (EGCG). EGCG are powerful naturally occurring antioxidants which:

  1. Reduce the growth and spread of cancer cells
  2. Anti-inflammatory which aids in joint issues, digestive issues and other inflammation related diseases
  3. Aid in lowering high blood pressure
  4. Fight infections
  5. Reduce bad breath 


Green tea is a natural source the amino acid L-theanine, known to reduce stress in pets by helping in the production of serotonin. A neurotransmitter associated with healthy, calm emotions and self-control. Serotonin has been shown to help relieve anxiety, depression and aggression in dogs and cats. Since L-theanine is a natural amino acid, it can improve pet behaviour without the concern of organ damage.

How should I feed my pet green tea?

The first thing is to make sure you use decaffeinated green tea. As dogs and cats are more sensitive to caffeine, it can be very dangerous for them.

For example, the easiest way to give it to your pet is to use high quality pet supplements. Importantly, follow the instructions based on their body weight. This is the safest way to administer green tea for dogs and cats.
