No. Caffeine is toxic to dogs and should be avoided.
Even small amounts can cause symptoms, especially in smaller dogs. Larger amounts can lead to serious complications.

- Caffeine affects dogs more strongly than humans.
Where caffeine is commonly found

What happens if a dog consumes caffeine
Caffeine stimulates the nervous system and heart.
Symptoms may include:
- restlessness
- panting
- rapid heart rate
- vomiting
- tremors
- hyperactivity
Symptoms usually begin within 30 to 120 minutes.
How much is dangerous
- A few licks of coffee is usually low risk for medium or large dogs.
- Half a cup or more can be dangerous, especially for small dogs.
- Energy drinks and espresso are more concentrated and increase risk.
When in doubt, call your veterinarian.
