I would like to begin Grimm on raw in a few months. I don't know if raw will be good for him (he has had a bacterial overgrowth following stressful events twice), and I will be open to not doing kibble if it doesn't work for him. But, how can I ensure Grimm has less of a chance of going through a tough detox or a rough switch? We live up in a high-rise on the 12th floor, and there is NO canned pumpkin here, should things get, uhh, loose.What helps dogs have an easier switch, besides starting with only one protien source and very very slowly adding variety? What makes a dog detox or not detox? He is eating Orijen grainfree Fish.
