My dogs got into a fight, and one got a puncture wound, what do I do?

First off, it needs to go to the vet. It's unfortunate that her mom is refusing medical help because the deep wound can get infected. My dogs got into a very serious fight once when one of my females was in an aggressive heat cycle. One of my dogs had a puncture wound, and we took her to the vet. They gave her antibiotics to prevent an infection, and we went to the store to get gauze to wrap her leg. After maybe a week, she was healing and walking just fine. Good luck with your dogs! :)
