The 5-month-old cocker spaniel puppy was attacked near Smithe and Homer streets in plain view of the dog’s owner at about 4 p.m. According to a witness, the couple that own the dog, described as a pitbull by witnesses, was dropped off in a cab when the dog jumped out of the car and pounced on the puppy, named Mila.

Kelly Tompkins was walking with the puppy’s owner when the pitbull ran towards the puppy and attacked.

Nearly disemboweled in the attack, Mila was rushed to an animal clinic for emergency surgery.
