Cash for Cash

In May of 2010, while in the Marines, I was given the opportunity to be a dog handler for my infantry unit. I went to South Carolina and was introduced to a IED "bomb" detecting dog named Cash. I began training with him and we were then deployed to Helmand Province, Afghanistan from October 2010 until May of 2011. Upon returning to Camp Pendleton, California, we were seperated so he could return to training for his next deployment with a new unit. I was honorably discharged and moved to Murfreesboro in August 2011 for college at MTSU. In December of 2012, I was informed that he would soon be retired and I immediately began to go through adoption processes. I was able to go to Virginia and pick him up just in time for Christmas. A couple months ago he tripped while running and tore his ACL. Retrieving is what he has always loved to do but he can't do it much anymore due to his injury. The price of the surgery is going to be around $3000. I would really appreciate any help. Thank you.
