I love big dogs. In my opinion, little yappin ankle biters are almost worthless. I have 2 dogs, Jake (Doberman Pinscher) and Lucy (Rottweiler). The love and loyalty that those two dogs show are unmatched by anything I have ever seen. They are a pretty good burglar deterrent too. (Would you break into a house where a dobe and a rott lived?) If you are going to own a dog, may as well get one that's good for something.
But no matter how big they get, (Jake is about 90 lbs) they still think they will fit on your lap!!!
