I don't know. I've heard from 2 different vets and the trainer at Petsmart that you should switch their food because, they thrive off of consistently. They said most people fell bad about them eating the same food everyday and want to change the food but, it could end up hurting the dog. Changing food too often can mess their stomach up and cause diarrhea and votmitting, too. I don't know how true that is but, I thought I'd share what I heard. Hope someone else has more information for you though. |
