I have a french poodle. She got mauled by my neighbor's dog.. a huge dog. She is undergoing surgery today for collapsed lungs and boken ribs. sigh... this month has been nothing but dark clouds on my horizon.
The dog that mauled her concerns me, because if it can do that to a smaller dog it could just as easily have been a child.
If you do decide to get the police involved, remember that; it isn't just about what happened to you dog anymore. What if that dog attacked a toddler a few months down the road? Scary.
