Help Pirate Walk Again: Urgent Support Needed

Hello, today my family and I are in need to ask for support for our dog “Pirata” (Pirate), he was a stray dog, with his right back leg amputated (this is why we named him Pirate), we immediately decided to adopt him and give him a home. Pirate is the most loving dog I’ve ever met, he wants to be cuddled all day and is the sweetest dog ever. Unfortunately, on May 9th he was ran over and severely injured his right front leg. Given the situation that his right extremities are out of use he is unable to stand or walk. He had surgery last week, but unfortunately he tried to stand up and opened up the wound and injured even more his right humerus. My family is taking him to the vet everyday for wound care and follow ups but the expenses are getting higher. Please help my baby Pirate so he can be able to walk again and be that happy dog that he was before, and please keep him in your thoughts and prayers, thank you
