Has anyone ever heard of this or experianced it? I just read up on it a bit and it says its a large/giant breed problem that causes the 2m fibers in the jaw to swell or abscess causing the jaw to not be moveable. It says its not determined to be genetic and its unknown what causes it. Was just wondering if anyone had experanced it before and any advice i could give to the owner. They said he's not doing so good and his jaw is immoveable at this point. UGH sooo sad. He's a GORGEOUS boy!!!
