Can dogs eat it?

Can dogs drink energy drinks?

No, toxic No. Energy drinks carry a lot of caffeine, often with other stimulants such as guarana. Call your vet if your dog drank some.

Why

Energy and sports drinks often contain a lot of caffeine, and many add sugar or other stimulants such as guarana that add to the harm (VCA). Caffeine overstimulates the heart and nervous system, and dogs are more sensitive to it than people. VCA compares a dog lapping up a spilled energy drink to a person drinking three cups of coffee. Even a small amount can be dangerous, especially for a small dog, so call your vet or an animal poison line straight away. Pet Poison Helpline also warns about energy shots, tablets and pre-workout supplements. Signs can start within a few hours and last several days (VCA).

Signs to watch for

If your dog ate energy drinks

Call your vet or an animal poison line now with the can or packet, even if your dog seems fine, and give your dog's weight and how much was drunk. Some dogs need a day in hospital, or a few days in severe cases (VCA).

If your dog has eaten something toxic

Call your vet or the nearest emergency vet now. Do not wait for signs, and do not make your dog sick unless a vet tells you to. Take the packet with you.

This is general guidance, your vet sets the actual schedule. Puppies, small dogs and dogs with a health condition can react to smaller amounts. Check with your own vet before changing what your dog eats.
