I agree with the sighthound idea. If you rescue a greyhound you'll be saving a life too.
Heck, my pomeranian runs faster than me (with a limp) so its all about dilligence.
Any dog can run off, or at least out manuver you. I know which dogs i can trust and which ones I can't. Its not hard to keep your dog on a leash.
Alot of guardian breeds are one man dogs. When i heard the term I immediately thought of chows and akitas for som' reason.
I too like the fact that my dogs don't give a care about other people. I find they are less likely to be stolen/ distracted, or fed strange things that way.
One lady told me "omg your dog is sick!" when he ignored her after her repeated attempts to excite him. Turns out she was a lab owner
