Colts leg surgery

This is Colt. He is a 6 year old German Shepherd. Colt belonged to my late brother, and has recently joined our little furry family. Initially we thought Colt was suffering from arthritis, but after looking into his health it turns out it is more severe than we had imagined... Colt has torn his cruciate ligament in his knee which will require an expensive surgery for him to continue to live a normal life. I wouldn't normally do something like this, but Colt holds a special place in our hearts. Any donations for Colty would be beyond appreciated ❤ Thank you very much
