Angus is 17 months old and has become very picky when it comes to his food. We have always given him dry food but lately he barely touches it. He will let it sit there all day . I've tried adding some canned food which helped for a few days, then he stopped eating that also .My vet who suggested we take the bowl up after a half hour but he doesn't seem to care. When I put it back down, he walks away. He's healthy, full of energy and has no dental problems . He just does not seem interested in eating his food. My last golden didn't pick his head up out of the bowl until it was empty. Anyone else have this issue ?
