Most dog owners consider their four-legged friend a cherished family member, which is why it's heart-breaking when your normally docile dog gets injured in an unexpected fight.

"We know there [are] unreported one's out there. Maybe half again that many, 75 to 100," said Bill Stephenson, from St. Paul Animal Control.
