I would try goat’s milk since it has tons of probiotics in it and helps rebalance the gut. It will make sure your puppy is has more good gut bacteria than bad gut bacteria. It will help with the loose stool along with hydrating your puppy as well. As far as a diet, I would try something that is complete and balanced like a dry food (without corn, wheat, soy, by-products, and grains), dehydrated (without grains), freeze dried, or raw. Ideally raw food is the best diet for dogs and kibble is the least freshest food.
