I adore dobermans. But, comfort dogs should be fluffy so people can bury their heads in their soft coats. My blue dobie was my lap dog. He, too, weighed about 75-80 lbs. But he was a junk yard dog I rescued. Stuck in a cage in piles of poop, never let out except at night. Pistol whipped from one of his previous owners and scars all over his head. He was considered a vicious dog by the people who gave him to me. I considered him my best friend. He didn't like cats, either, but when I brought him home I showed him the cat and said one word. "Mine". And he never bothered it. Ever. He also almost chewed the hand off my landlord becaues the landlord ignored the Beware Of Dog warnings I had all over the fence and thought he would come in anyway. Big mistake. But I am glad he didn't sue me. He said it was his fault for entering the yard and the dog was just protecting his territory. Which is true.
