Can dogs eat fizzy drinks, and why?

Fizzy drinks are sugary and often caffeinated, so they should never be given to dogs. Caffeine is toxic, and the high sugar and bubbles can cause upset stomach; diet versions may contain xylitol.

Dogs are omnivores, so most of their diet should be a complete, balanced dog food, with treats on top. They cope with a wide range of foods, but rich, fatty or sugary ones can cause stomach upset and, over time, weight gain or pancreatitis.

Warning — what to watch for

Caffeine is toxic, and the high sugar and bubbles can cause upset stomach; diet versions may contain xylitol.

If your dog has eaten fizzy drinks, don’t wait for symptoms — contact your vet immediately, or call the Animal PoisonLine on 01202 509000 (24/7, UK). Signs of a problem can include vomiting, diarrhoea, drooling, lethargy, tremors or loss of appetite.
