I have a 2 year old Dobie boy who I have had for over a year now. Within his first year, I was his 4th owner. I have just moved to a new place with roommates who do not get up as early as I. I can’t seem to stop his high pitch bark/cry when I leave. I usually keep a shock collar on him when I leave but this high pitch bark goes undetected by the collar and does not give him a reprimanding shock. So I have had to resort to putting a muzzle on him also. I also have to keep him in a crate to keep him from banging/pawing at the door when I leave. Is this inhumane? How do I keep him from doing all of these bad behaviors and keep my roommates happy? When I am home I work with him, using a spray bottle and telling him “No” but it seems to not work when I’m on my way out the door. Any help?
