I think this is more of a "wild animals are wild" situation. I'm no fan of pit bulls, but it's hardly fair to hold them responsible for a coyote attack.
How many people have to be attacked and seriously maimed before pit bulls are finally acknowledged as the problem?
Pitbulls are worse than coyotes because coyotes dont have the strength or size of a pit bull.
And coyotes dont have the devils P.R. team telling people there are no bad coyotes, its their upbringing, not the breed.
I threw a show at a coyote once and he ran away,
I threw a shoe at a pit bull once, he ran away and 5 minutes later he came back with a different shoe attached to a fresh bloody leg.
