Help winnie keep her leg

Hi there. My name is winni and I'm a 14 week old bloodhound puppy. I was running around enjoying myself and somehow managed to break my back leg, I'm a bit lanky still and am just finding my feet so I guess I must have come down on it wrong!

The doctors told me I need surgery to fix it otherwise they will have to amputate it.

I still think I have lots of running to do with all 4 of my legs but I need your help!

Love winni and my family.
