My sister was walking her GSD today. On her walk out, she saw a GSD pup sitting on the ground, near a vacant house. On the return trip, it was still there. She ran her dog home and went back to investigate. She knew there was a problem. She saw that it had been hit. She got it into a carrier and took it to the vet. It turned out to be a horrific back break, and it has to be PTS. The vet said there was nothing that could be done. She stayed with the pup.
My sister's birthday is today. She is very, very sad. :(
