I would say try being a bit more patient with getting him to eat. Not sure how old your furbaby is, but they can be picky eaters in the begining. Especially since you mentioned that he had a previous owner. I've had Meka since 9wks and there were times in the begining that she wouldnt eat unless I put the kibble in my hand. I think you've been through quite a few different brands already in less than a month. Try sticking with one of them and adding some things to it that might help him eat it (i.e: water, broth).
