I've got a yellow lab that's got "issues." We've had him since he was weened, and his problems started in our first apartment when he was about 6 months. He would get terrified of doorways and hessitate to go through them. He would sit there and shake, nosing in and backing out. You should see the look of confusion and terror on his face. All of this would culminate with him charging through and tripping himself. After he would make it through, he would strut around all proud of himself.
He has had knee issues (bi-latteral patella luxation), which were corrected by three surgeries between his first and second year. Poor guy is also bow-legged. To the best of my knowledge, he was never traumatized by the doorway (ie- something bad associated with it). He was crate trained and is an indoor dog.
He was about 8 months when we moved into our current house. For the first month, he was fine. He would go anywhere without issue. About 2 months in, he started fearing doorways, some parts of the living room, and the main hallway. He sticks to "routes" in the house to get anywhere, and will even go entirely out of his way to get to something. I can be five feet away from him, but if the "scary zone" is between us, he'll go around the entire house to get to me.
In the main hallway (5' wide with windows to one side), he hugs the wall as he goes down it. If the cat or something is sitting against the wall, he'll freeze up. If he turns around in the hall, he makes sure to do so as close to the wall as possible.
In the backyard, he is fine.
I've tried working with him. ie- slowly drawing him into his scary areas while playing or giving him treats, putting carpets in the door ways, etc. but I haven't had a lot of success. My wife seems to think that his knee problems are to blame, but he gets around fine now. The floors are tile, but that is all he's ever known.
I've done a lot of searching on this, and have never found a case similar to this. Any tips or words of wisdom? Thank you.
