To each their own.
Many different man biters. I like consistency. If he's going to bite anything and everything, I can deal with that. If he is sporadic or unpredictable on what he will bite, when and why? I'll shoot him. Only had one like this in my life. He grabbed the back leg of my overalls right below my ass and tore the entire back leg of the overalls off. I never stopped walking. Went it, got my .44 mag and that was that. I will not feed an unpredictable idiot of any kind, most specifically an unpredictable biter.

I don't mind a dog that will bite others but loves me. Couldn't care less. He knows who feeds him and I'm cool with it so it works.

Worst biter, most aggressive I've ever seen was the T Rex dog on Hammonds' place. If anyone has his book, he's the dog in the "Man Biter" chapter of his book. I took that picture myself standing about 3 feet from him at the time of that photo.
