It wouldn't hurt to collect some n bring it to your vet for a stool sample!!!!!! I really don't know I mean Fromm is a great food!!! Is it possible all the switching from one food granted its still Fromm but switching n then to the hamburger n stuff is upsetting his digestive system??????? I'm most deff not a food person since I fed porky kibbles n bits for a long time!!!!! But I mean food for thought my vet told me sometimes they just have runny poop especially if he's going through a growth spurt that believe it or not can effect him systemically (i was called neurotic when i was told this i was sure she had parovirus) which could have caused a few days of loose stool n then the changes in diet may have just upset his tummy!!!!!! I'm just thinking out loud but my real advice is gather up some poop n have it tested better safe than sorry good luck!!!!
