Are energy drinks dangerous for dogs?

A standard 250 ml (8.4 oz) can typically contains about 80 mg of caffeine. Larger 473 ml (16 oz) cans often contain 160 mg or more, and some brands exceed 300 mg. Guarana, a plant-based ingredient, adds more caffeine on top of the listed amount.

Energy shots are smaller but even more concentrated.

Caffeine tablets can contain 100 to 200 mg each, and a single scoop of pre-workout powder can contain 150 to 300 mg. These products are extremely dangerous for dogs and can cause severe poisoning quickly. Gym bags left on the floor are a common source.

Store supplements in closed cupboards.

Restlessness, hyperactivity, vomiting, panting, a racing or irregular heartbeat, high body temperature, tremors, and seizures can develop within 30 to 60 minutes. Signs can last many hours. Sugar-free energy drinks may also contain sweeteners, and any containing xylitol add another danger.

Keep the can or packaging for your vet.

Open cans left on low tables, in cars, or at sports events are easy for dogs to knock over and lap up. Finish or pour away drinks before walking away, and put empty cans straight into recycling out of reach. Sports bottles and shaker cups used for pre-workout drinks can hold residue, so rinse them and keep them in a closed bag. If a can has been knocked over and you are not sure whether your dog drank from it, phone your vet anyway.
