We have a new dog. He is young - aged 1 to 3 - and looks like a shetland collie crossed with a fox. He is handsome! However, he is behaving like a big puppy. He needs to be housetrained, how do I go about this with an older dog. (Rescue place had been told he was housetrained! He was in kennels there). He doesn't wee on every lamppost when walked - do neutered dogs not do that? Also he has really had no training, most dogs have had the basic sit and give a paw. This one just likes to bounce! Any advice on an overgrown puppy? And he doesn't eat well, he seems convinced 'human food' and shoes are a good diet, I'd like him to eat dogfood at least some of the time. (Past experience of a fussy cat...)
