I switched my dogs from Nutrisource (because it had menadione)to California Natural Lamb and Rice. Since then ALL of the dogs have had explosive almost water like diarrhea. I know upset tummies are possible on new foods, but it never got better. Has any one else had problems with CN? Found it weird that all 3 had gotten sick on this food. But I can't find anything that they all would've gotten into that could've caused this. They are all up to date on vaccines also. They have all been to the vets who couldn't figure out what the problem was he suggested I try different food after a few days of a bland diet. They are on a bland home cooked diet for now which has stopped the runny poops. I will be looking for another lamb and rice formula shortly. Any advice on what food? I was feeding Eagle Pack Holistic but the price went way up...I was trying to find something that was just as good but not as expensive.
