Can dogs have coffee, tea, or energy drinks?
No. Caffeine belongs to the same compound group (methylxanthines) as theobromine in chocolate, and dogs are much more sensitive to it than humans.
Why is it dangerous?
🚨 Caffeine stimulates the dog's cardiovascular and nervous systems. The toxic dose starts at about 20 mg / kg of body weight, and is life-threatening above 100–150 mg/kg. For a 5 kg dog, even a single strong espresso grounds or half an energy drink can cause serious symptoms.
Risk by form
| Form | Risk |
|---|---|
| Caffeine tablet, pre-workout powder | Highest (extremely concentrated) |
| Energy drink, energy shot | Very high |
| Coffee grounds, coffee capsule, ground coffee | High (concentrated, and dogs eat from the trash) |
| Black coffee, black tea | Medium |
| Green tea, cola | Lower, but not safe |
Symptoms to watch for
Symptoms typically appear within 30–60 minutes:
- Restlessness, hyperactivity, unable to calm down
- Rapid or irregular heartbeat
- Tremors, muscle spasms
- Vomiting, diarrhea
- Increased urination, followed by thirst
- In severe cases, seizures, high body temperature
If your dog has consumed caffeine
Call your veterinarian immediately, and tell them what, how much, and when. Keep the packaging handy: the caffeine content in energy drinks and supplements can vary widely. Heart rhythm symptoms need to be monitored; this is not something that can be treated at home.
Where is it hiding?
Coffee grounds in the trash (the most common case!), coffee capsules, tea bags, energy drinks, fat burners and pre-workout products, caffeine-containing pain relievers, guarana-containing products.
