As someone that owns/owned dogs that are HA with strangers, I say the land owner is a fuckin idiot. If the dog is growling at you, why are you testing the dog? It's not YOUR dog. If the dog doesn't bother the owner, the wife, and kid, who gives a fuck what some idiot has to say. At one time, probably half my yard would growl, try to bite, or look crazy at strangers, and I was fine with that. They're not doing that to me. They only have to please me. If the dog whipped the other dog's ass, and the land owner says he wouldn't keep him, it's because 1) His sloppy ass dog got exposed and 2) His dumbass got exposed. The dog owner should keep the dog and do his thing and fuck what anyone else says about his dog. Just make sure he explains that THIS dog doesn't like strangers. After that, it's on the stranger wanting to pet the dog.
