Galaxys leg amputation

Hey everyone, I'm Sam, and that little dude in the picture is Galaxy now. He was dumped off by where I live and I came home to him on my steps with a broken leg. We rushed him to the vet, had x-rays and all that. We learned then that he had broken it on his growth plate, an impossible brake to save and he would need to amputate it. We were quoted $1200 to $2500. For now we made sure he has his antibiotics and pain meds. He really is the sweetest little guy, even with all the pain he still just wants to be held and loved all time. But right now we can't afford the amputation, and I would surrender him but he literally found us and my children are so in love. Anything helps.
