Purina Gastroenteric Fiber Balance is a veterinary therapeutic diet for adult dogs with digestive problems, sold as both dry kibble and canned wet food. It pairs a blend of soluble and insoluble fiber with omega-3 fatty acids to support stool quality and a calmer gut, and it is meant to be fed under a vet's direction. It sits alongside other prescription gastrointestinal diets rather than ordinary maintenance food, so it suits dogs with fiber-responsive issues such as loose stools or colitis. Owners generally report firmer stools, though picky dogs and sensitive stomachs do not always take to it.

Owners of dogs with chronic loose stools often report firmer, more regular output on this diet, and vets use it as a first-line fiber-responsive option. Others say their dogs turn their noses up at it or that it did not settle their particular problem.
