Sorry about Gizmo. I know how you feel. It is horrible to see your dog attacked.
Jim was walking Belle a few years ago (she was about 8 at the time) around our neighborhood, the same streets we walk her on everyday. About three blocks away a German Shepherd dog escaped her house and rushed across the street and attacked her. Bit and shook her by the neck and ripped a long gash on her side where her front leg meets her side. A teenager from the house ran across the street and pulled the dog off Belle who was screaming her head off. Then the dog jumped back on her and the girl's mom joined her grabbing their dog.
Jim picked her up and headed home. That's when it is good to have a dog that only weighs 20 lbs! Belle's screaming was such that about eight people popped out and one family called the police as they said the dog had attacked two other dogs on the street over the last few months.
I was in the house when Jim ran in carrying Belle covered in blood . She was alternating screaming and crying. We wrapped her in a big towel and got in the car and headed to our vet, calling on the way to tell them what happened so they could be ready for her.
As we drove pass the house where the GSD lived, there were about 15 people in the yard and two police cars. We've lived in this subdivision (NW Columbus) for 22 years and have never seen such a gathering as people were screaming at the family with the GSD and the police had to hold people back. I never knew there were any problems as we rarely see a loose dog.
Turned out the mother of the woman who owned the dog lived next to the mother of our vet! She paid Belle's vet bill and stopped by a couple of times to see how she was. Belle had to have about 20 stitches and a round of antibiotics but the hard part was keeping her from doing any running for a week. Because we applied pressure to the wounds she do not lose enough blood to warrant a transfusion. She was awfully sore and needed pain pills for the first couple of days. Between the stitches and the shaved areas she looked pretty pathetic for weeks.
About two weeks later we walked her past the house with the GSD and it was like nothing had happened. Belle didn't seem to associate it with anything, even when we heard the dog barking inside the house (yes, they kept the dog.)
I know accidents can happen and at least the scars were not psychological as she still loves my son's German Shepherd. And loves long walks.
