I started to switch him from eukanuba(breeder had him on) to Nutro puppy..(which he didn't seem to care for) then i found out about chicken soup and got him a trial size bag of that. He LOVED it, but now he won't hardly eat it and goes to my other dogs bowls and eats their Nutro max small bites. I put their bowls up and he leaves the room. WHAT HAPPENED? I really was thrilled that he seem to love the "chicken soup" and felt good about feeding it, but now what? I mixed some of the regular Nutro max in with his chicken soup and he ate it. It's not "puppy formula" but the protein is high enough..26% and 16% on the fat. I just want to stick with something...tired of cleaning soft nasty poops off the carpet. ANY suggestions what i should do?
