Bulldog Attack Legal Update

She’s dealing with a challenging situation already, and things for Samantha Ronson and her pup, Cadillac, could get much worse.

After the celeb DJ’s dog mauled and killed another dog at Ronson’s apartment complex over the weekend, she could not only be facing serious charges but Cadillac may be at risk of being euthanized.

Deputy Director Michelle Roache of the Los Angeles Department of Animal Care and Control told E! News, “The attack is substantial” and adding that the investigation will be “a long, lengthy process.”

Ronson's rep has not responded to requests for comment, but in a tweet last night last night, Ronson wrote, "I feel incredibly sad and wish I could offer more than condolences, unfortunately there are no words to describe how sorry I am."
