So a friend of mine has a dobe puppy a little older than Jazz. This dog has really soft stools all of the time. Recently they were on vacation with a friend looking after their pup. Well they ran out of Innova Large Breed Pupy food while they were gone so the sitter switched her cold turky to the costco brand that she fed her own dogs. This firmed up her stools and she became "normal" over night. She is wondering if maybe Innova is too rich for her dog and what other brand could she try. Is Natural Choice or Formm as rich?
