I feel your pain, hope recovery is fast. Last week my neighors lab (about 100 lbs) wrapped his lead around her ankle and took off after another dog. Flipped her 180 degrees, landing on her wrist/hip. Broke the wrist and damaged her hip. She's in a wheel chair for 6 weeks while the wrist heals enough so she can use a walker for another few months till the hip gets better.
I watched the dog while they were at the emergency room (via ambulance). Had the dog on a lead, wife and neighbor came over. My other neighbor leaned over to pet the dog, he jumped up, hitting her nose. Blood everywhere, but fortunately he didn't break her nose. Dog went to the kennel for a few days after this wonderful day....
