Electrolytes for Working Gundogs – Questions & Answers

central & southern gsp society sponsor the 2026 england hpr international team with electrolytes for the dogs

With member Millie Pocock and her GSP Louis being selected as part of the England Team for the HPR Internationals in 2026, we were delighted to sponsor the England Team. Our sponsorship supplied the team dogs with electrolytes for use during training and the main event.
​

What are electrolytes?

Electrolytes are essential minerals that help regulate many of the body's vital functions, including hydration, muscle contraction and nerve function.
​

During strenuous exercise in hot weather, dogs lose not only water but also important minerals such as potassium, bicarbonate and magnesium through heavy panting and saliva.
​

Dogs do not sweat through their skin. They cool themselves primarily by panting, which can result in significant fluid loss and increase the risk of dehydration and heat stress.
​

​Why are electrolytes given to dogs?

For most pet dogs, fresh water is all that is needed. However, working gundogs exercising for long periods in warm conditions have much greater hydration demands.
​

Scientific studies have shown that relying solely on plain water can cause dogs to stop drinking before they are fully rehydrated because drinking large amounts of water quickly dilutes the blood, triggering the brain's "thirst switch." Research has also demonstrated higher levels of ‘Creatine Kinase’ (a marker of muscle damage in dogs hydrated only with plain water).
​

Properly formulated electrolyte solutions encourage dogs to drink more, improve water absorption, help maintain mineral balance and reduce muscle damage during prolonged work.
​

​How and when are electrolytes given?

Research recommends a simple three-stage approach:

1. ​Before work: Offer a flavoured electrolyte drink approximately 1–2 hours before hunting or competition to create a hydration reserve.
2. During work: Offer small amounts every 30–45 minutes rather than allowing the dog to drink a very large quantity all at once.
3. After work: Continue offering fluids until normal hydration is restored.

Only dog-specific electrolyte products should be used.
​

Human sports drinks and oral rehydration products should never be given as they contain inappropriate mineral balances and may contain ingredients that are unsuitable or even toxic to dogs.
​

​Why are electrolytes being used at the Game Fair?

The International HPR Game Fair brings together some of England, Wales, Scotland and Ireland's top Hunt, Point and Retrieve dogs, all of which are working at a high level over a prolonged period. When warm weather is forecast, maintaining hydration becomes an important part of protecting the dogs' welfare.
​

By encouraging voluntary drinking and improving hydration, electrolytes help reduce heat stress, support muscle function and provide an additional safeguard against dehydration during what can be prolonged periods of physical activity.
​

ecent studies from veterinary sports medicine researchers, including the Penn Vet Working Dog Center, demonstrate that correctly formulated electrolyte solutions can improve hydration, reduce muscle damage and help dogs cope more effectively with exercise in hot conditions.
​

Can electrolytes benefit pets in extreme heat or are they only for sporting and working dogs?

Healthy pet dogs generally require nothing more than access to plenty of fresh water and shade.
​

​Electrolytes are primarily intended for dogs undertaking prolonged or strenuous exercise, such as working, sporting and competition dogs.

In exceptional circumstances, for example, prolonged activity in very hot weather or under veterinary guidance they may also benefit some pet dogs.
​

Owners should always use products formulated specifically for dogs rather than human electrolyte drinks.
​

Where can you get electrolytes for dogs?

Dog-specific electrolyte products are available through veterinary practices, working dog suppliers and specialist canine sports retailers.
​

Only products designed specifically for dogs should be used, as they contain the correct balance of minerals and are formulated to be both safe and palatable.

Scientific Evidence

• Otto, C. M., et al. (2017) – Demonstrated that chicken-flavoured electrolyte solutions significantly increased voluntary water intake in working dogs.
  
  Niedermeyer, G. M., et al. (2020) – Showed that appropriate hydration strategies help manage heat strain in detection dogs during intense exercise.
  
  Stegelmeier, B. L., et al. (2021) – Found that dogs receiving balanced electrolyte solutions showed lower muscle damage markers than dogs given plain water alone.
