Can Dogs Drink Green Tea?
Safety Information
Contains caffeine which is toxic.
Important Notes
Even small amounts can be harmful. Avoid all caffeinated teas.
Why is Green Tea (Caffeine) So Dangerous?
Caffeine belongs to a class of compounds called methylxanthines, which also includes theobromine (found in chocolate). Dogs metabolize these substances much more slowly than humans, allowing them to build up to toxic levels in their system. Caffeine acts as a stimulant, over-activating the central nervous system and heart.
Sources of Caffeine in Green Tea
- Brewed Green Tea: Even a cup of brewed green tea contains enough caffeine to be harmful to a small dog.
- Tea Bags: Used or unused tea bags are particularly dangerous as they contain concentrated amounts of caffeine.
- Tea Leaves: Loose tea leaves also pose a risk.
- Green Tea Supplements: Any human supplements containing green tea extract should be kept away from dogs.
Signs of Caffeine Toxicity
- Symptoms of caffeine poisoning can appear within 30 minutes to an hour after ingestion and can be severe. Seek veterinary help immediately if you notice:
- Hyperactivity, restlessness, or agitation
- Vomiting and diarrhea
- Increased heart rate and panting
- Muscle tremors
- Elevated body temperature
- Seizures
- Collapse
- In severe cases, caffeine poisoning can lead to cardiac arrest and death.
What to Do If Your Dog Ingests Green Tea
This is a veterinary emergency. Contact your vet or an animal poison control center immediately. Do not wait for symptoms to appear. Be prepared to tell them how much tea your dog consumed and your dog's approximate weight. Time is critical for successful treatment.
The Bottom Line
Green tea, like coffee and black tea, is highly toxic to dogs. Ensure all tea bags, brewed tea, and any products containing caffeine are kept securely out of your dog's reach at all times.
Emergency Notice

General Feeding Guidelines
Introduce new foods gradually to monitor for allergic reactions or digestive issues.
Treats and human food should make up less than 10% of your dog's daily caloric intake.
Always consult with your veterinarian before making significant changes to your dog's diet, especially if your dog has pre-existing health conditions.
