Our 3 month old Beagle wont stop crying,especially at night. Whenever he is in his area and we leave him alone, he cries and barks, sometimes jumping over the fence. He is comfortable with his crate and sleeps in it,maybe after a really long day. We walk him, play with him and all but many nights he can't or won't sleep. I thought that he really wants attention: after all,he is a puppy and they need attention so we try to be with him at most, but we can't be with him all day. I browsed the internet and tried most of the stuff... we couldn't get him trained and/or calmed after numerous days and tries.I don't know what to do. What should we do?
