I'd go with the one that you like the best!!!! I think a person can tell when a dog picks a "human".....check them out, spend some time with each one and try to go out into a closed yard with them, one at a time. See how they respond to you, noises, other people. I've had each kind and I loved them all. The shepherd mix was born to guard me. That was a tiny problem at first, but she was easily trained. The hounds I love because I like their personalities and their soft, long ears!! Check them out!! Good Luck. Pat
