We have a 6 month old maltipoo puppy. I know they can be fussy eaters. We want to keep him on dry food but he's just not interested. I've tried 4 different makes but I'm having to squash in cheese and meat to get him to eat and he now seems to be just picking out the good stuff and leaving his kibble. Do we go cold Turkey and just leave his food out and hope he eats or keep trying different makes? It's so upsetting and I hate eating when he is obviously hungry. What would you do?
