New 'DWTS' Competitor Accused of Canine Attack

Remember that dude who married Shannen Doherty back in 1993? Yeah, we didn't either until actor Ashley Hamilton's dog allegedly mauled somebody in Los Angeles.

A guy named Michael Cohen is suing the upcoming "Dancing with the Stars" contestant for acting "negligently, carelessly and recklessly" when Hamilton's American Staffordshire Terrier (similar to a "Pit Bull") allegedly bit Cohen's dog "Sabra" in L.A.'s Runyon Canyon a few months ago.

Cohen says he cradled his wounded pooch in his arms when Hamilton's dog -- who was allegedly "roaming freely" at the time -- bit Cohen on his hand and wrist.

According to the docs, Cohen tried to make a run for it, but tripped over a rock in the process, injuring himself further ... not that we find that kinda/sorta funny or anything.
