Puppy needs surgery :(

Its crazy how fast and quick things can change around in an instinct. My heart aches every time just thinking about the pain he went through. Just last night, I went for a walk with my dog just like any other day thinking he just needed to go potty. As I was walking down the street, my dog just started sprinting towards what looked like a cat at the time but turned out to be a raccoon. The raccoon then chased kingu and led him into a ditch that caused him to snap his left arm. He started screaming in pain and I was confused to what he may have been screaming about, until I held him up and his arm just flopped and looked as if it had been bitten off. It was hard enough seeing him go through this but even harder having to find out it was going to cost us a couple thousands since we don't have pet insurance. Just for the walk in, examination, X-ray and a temporary cast it was already $800.. This is not including the surgery price that they have estimated to be $3000-$4000. What went from a regular day just pretty much became one of my worst days ever. My goal is to only reach $1500 just to at least get half of it payed off. Anything helps and i am truly grateful for those who will support me through this.
