The unidentified caller also claims the attack happened "in the hallway" of Sam's West Hollywood apartment early Monday morning.
At one point, the operator asks the caller, "Is the owner of the dog a male or a female?"
The caller replies, "I believe a male."
As we previously reported, Sam is now the focus of a criminal investigation surrounding the death of Tiger -- a 3-pound Maltese that was roaming the hallway without a leash.
Ronson has since shipped Cadillac to the East Coast to stay with family.
