I tried the Wellness just for puppies and they totally gave my 11 week-old puppy loose stools. He is very treat motivated for training and I would like to find something I can use to help with training. Kibble isn't cutting it- lol.
I also cheat and flavor my dog's kibble. So I might take their lunch and put in a bag with hot dogs and cheese, or a little bit of chicken stock. That way it smells/tastes a little bit better than their normal diet, but I know it isn't going to upset their tummies.
