I have 2 Bernese Mountain puppies one is 14 weeks an the other one is 10 weeks. We purchased them from a breeder on Sunday. On Monday our pups started with loose stool. I thought first it was from the change of food an water. Breeder feed Blue Diamond Puppy food an had well water. We started on Sunday nite with Pedigree Puppy food and gave purified bottled water. Once I asked breeder for food information we switched Monday to this Blue Diamond but our pups still continue to have loose nasty sto

Yes, it certainly is possible that AJ and Kovu has diarrhea from the change in food. I can give you a home remedy to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in their normal diet. If the diarrhea continues on the bland diet, they starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, they will need to see a vet right away.
