Support Buddy's Surgery for a Full Recovery

I recently got back from deployment and I found out my dog, Buddy, messed up his leg in June and I didn't get back home until July. He seemed fine until about a week ago, when I noticed he couldn't put weight on his leg. I took him to the vet, and the vet said he most likely ruptured his ligament and he's going to need surgery. It's going to cost at most $10,000 plus the medication and anything else he would need post-surgery. I'm usually an "I'll figure it out and do it myself" type of guy, but I've had Buddy since birth, literally. I raised his mom and dad, and now I'm raising him. I'll do whatever it takes to get him back to 100%. I love this dog. Anything will be greatly appreciated.
