Can Dogs Drink Soda? Caffeine, Sugar & Sweeteners

Can Dogs Drink Soda?

AVOID

AVOID — Soda and energy drinks are high in sugar and often contain caffeine or artificial sweeteners such as xylitol. Offer fresh water instead.

Sugary and diet fizzy drinks have no place in a dog's diet. Caffeine can be toxic to dogs, sugar causes problems, and some sugar-free drinks contain sweeteners that may be harmful. Water is the best drink for dogs.

If your dog licked or drank a little spilled soda, watch for stomach upset and offer fresh water. Contact your veterinarian if your dog drank a large amount of cola or another caffeinated drink. If your dog drank an energy drink, or a sugar-free drink whose label lists xylitol, or is restless, shaky or has a racing heart, contact a veterinarian, or an emergency veterinary clinic out of hours, straight away.

The full answer

A lick of spilled soda is unlikely to be a crisis, but fizzy drinks are not suitable for dogs. They are loaded with sugar, and many colas, energy drinks and some other soft drinks contain caffeine, which is toxic to dogs and can cause restlessness, a racing heart and, in larger amounts, tremors and seizures.

Diet and sugar-free versions replace sugar with artificial sweeteners. Some of these, notably xylitol, are dangerous to dogs, although most major soft drinks use other sweeteners. Always check the label if your dog drank a sugar-free product. The carbonation can also cause bloating and discomfort.

Fresh, clean water is the best drink for dogs. If you want to give a flavoured treat, ask your vet about dog-safe options.
