Celebrity DJ and Lindsay Lohan's ex-girlfriend Samantha Ronson and her dog didn't have a great day. TMZ reports Ronson's dog, a bulldog named Cadillac, allegedly mauled a neighbor's dog to death. Cadillac also reportedly attacked the dog's female owner as well.

The mauled dog, Tiger, was a two-year old Maltese that appeared to weigh between three and five pounds.

After a 911 call was placed around 11:10am Monday reporting a dog attack, authorities were dispatched to Ronson's neighborhood. When authorities arrived, the Maltese was already dead. The dog's owner sustained minor injuries.
