My sis recently adopted a 2 year old hound (the previous owners said he was a purebred beagle, but we suspect we might be part foxhound) from a family that had to give him away due to moving. He's a very sweet boy and doesn't have a lot of obvious bad dog behaviors except for some occasional marking. Unfortunately, he is also very clingy and panics whenever my sis leaves the house or when its time for us to go to bed. We've tried crating him, but the confined space just freaks him out. Having him sleep in bed with either of us is NOT an option, but he hates sleeping alone and will bark all night if he's ignored. Any advice would certainly be appreciated.
