OK, so I bought my pup the Canidae all life stages food and mixed it into his previous food, Nutro natural choice lamb & rice. The first day I mixed his food in with his old, he'd try and pick out the Canidae kibble and leave back the Nutro. Same thing goes for the next day when I went 50% of each food. Now he's eating entirely Canidae, but when I take the food out for him at his meal times, he just kind of looks or sniffs at it, then he bats the bowl letting the kibble fall out. He'd take a few bites of kibbles, then run off up the stairs after me. I fed him at 9am this morning, and I came out at 11am and 1pm to see how much he ate. There are still about a dozen kibble still left in his bowl. This is odd, because he use to never leave any food behind. I thought he liked it when he picked through his food for the Canidae kibble, but could I be wrong, and he actually doesn't like the food?
