I had an A.C.D crossed with a small lurcher. Because of that she lacked speed. But she was very game and would try very hard. She was easy to train, obedient and very loyal. She was also sensibly protective. In addition she was faultless in the house, very peaceful and quiet and not at all destructive. She would take as much exercise as I could give her, but was happy to lie around if I didn't exercise her. In many ways she was probably the best dog I'll ever have. Just too small and too heavily built for speed.
