I heard recently that the dog that bit me just before Christmas has died. It wasn't that old, but it apparently developed kidney disease. His owner theorizes that he bit me, or as she characterizes its having my leg in his mouth, "almost bit me," because of kidney induced dementia. I think it's another example of the AKC taking amiable, hard working dogs and turning them into vapid supermodel, dare I say, bitches.
That still doesn't explain her husband's complete obliviousness when the dog was lunging at me.
