word on that. when i switched tank from nutro to DVP duck/potato, he had soft stools for 2 weeks. but that's because i switched it immediately, without mixing in to the old food cause there was none left. rotest:Chico.Heidi said:When Heidi was a pup, I switched her cold turky and she got horrible diahrrea and blood in her stool. It took several weeks to get her back to normal. It might work for some dogs but not all. I would be careful of that one!
