“Legumes are plants with seeds in pods. They include beans, peas, lentils, peanuts and soybeans. Legumes have been a major source of protein in the diet for more than 5000 years, according to the University of Minnesota Extension. In addition to protein, legumes are also high in fiber, micronutrients and phytochemicals. Despite the nutritional benefits, western cultures limit the use of legumes in their diets”.

Some dogs do well with legumes as an ingredient in kibble. Some don’t.
Some dogs do well with potato laden kibble. Some don’t.
It’s all trial and error. But, if you have a sick dog it is probably best to go with a therapeutic diet (otherwise known as prescription food) as most veterinarians will recommend, at least till the dog is stable.
PS: Loose stools/diarrhea indicate that the current diet does not agree with the dogs, I would switch to a bland diet immediately and see what else the treating veterinarian advises.
