Can dogs drink sports drinks?

People lose sodium and potassium through sweat during long exercise, which is what sports drinks replace. Dogs cool themselves mainly by panting and lose far less salt through their skin. After a normal walk or play session, fresh water is all a healthy dog needs to rehydrate.

A 500 ml (17 oz) bottle of a typical sports drink contains around 30 g of sugar.

Sugar-free sports drinks use sweeteners such as sucralose or acesulfame, which are not considered toxic to dogs. Some electrolyte tablets and powders use other sweeteners, and a few may contain xylitol. Read the full ingredient list before letting your dog have any.

Artificial colors can stain fur and bowls but are not a major concern.

Signs of dehydration in dogs include sticky or dry gums, sunken eyes, lethargy, and skin that is slow to spring back when gently lifted. Dehydration is often caused by vomiting, diarrhea, heat, or illness, and those need proper diagnosis and treatment. Vets sometimes use electrolyte solutions made for pets, but the type and amount should come from them.

Heatstroke is an emergency and needs immediate veterinary care.

On long hikes or runs, carry a collapsible bowl and offer water every 15 to 20 minutes. Avoid exercising dogs in the hottest part of the day, and choose shaded routes. Working and sporting dogs may have different needs, which your vet can advise on.
