My pup is 6 month old collie x he gets 3x 30 min walks a day however when I leave him alone he howles and cries from when I leave till I get back I leave him in his cage with toys chews longs with treats and the radio on and nothing amuses him. Toys treats and chews are left untouched when I get home he is only left for 3 hrs at the max and is driving my neighbours up the wall. Please help
