Delphi get life saving surgery

I’m lexie I’m 16 and my almost 2 year old therapy horse Delphi was found in the wrong field not thinking to much about it we went and got her but, as we were walking back we could see she was lame there was a small wound oosing puss every time she moved, the vet came out and did some tests and found out it was on top of her fetlock joint for anyone who doesn’t know that’s a very serious injury for a horse as infection rate is very high we were told we had two options put her down or have a surgery to flush out the wound obviously there was only one option till he told us the price, this beautiful young horse is not ready to leave us yet so please help by sharing or donating anything and everything helps, here is some pictures of my sweet girl
