Link needs to walk again

This is for my dog, who I rescued, named Link. According to the shelter, he was thrown out of a truck. A kind soul witnessed the event and brought him to the aspca. I made him a part of my family to share my adventure with him. ( I love hiking ) Unfortunately, I found out he was born with severe knee problems. Last week, he fell on our steps and dislocated his knee. After a visit with the vet, I learned they were unable to pop it back in place and urged that he undergo a knee replacement surgery. I'm reaching out to help him get this procedure done so he doesn't live his life in pain. I can no longer bring him on hiking trips in fear that his knees will give out. His only hope in rejoining me in my adventures and living the great life he deserves is to have this corrective surgery done. I hate asking for help and I will spare you my financial situation. It would mean the world to me if you could either donate or share this post. He is a compassionate loving companion and I want to give him the best life possible . He's only a puppy and still has a whole life of adventure ahead. Please help me in raising funds to have the surgery done; he is my world.
