I have the Baby On Eukanuba Puppy that is the best food you can buy here in Canada pretty much there is Pro Plan and others i prefer the other as too the other dogs eating there poo in spring i thought it was the winter when this usually happens.I also heard that it was a dominence thing but a 11 week old puppy wouldnt really start this soon as too the changes he has been here for a couple days we just got him last saturday could it be the stress of changing homes?
