please help little Tilly get the surgery she needs

Hiya my names Bella and i’m 19. This is Tilly’s story, Tilly is a miniature chihuahua, she’s the most caring and loving pup who is quite literally my best friend and it breaks my heart that she’s in this situation, seeing her cry in pain. I rescued Tilly off a family who could no longer care for her. Tilly didn’t have the best start in life and was housed with bigger dogs and children who picked on her and left her very timid. She was originally only bought as a pup to be bred for money which lead to neglect of her. Since i’ve had Tilly she’s always been wobbly on her back legs and after numerous attempts to get vets to listen to me after being told “your too young to be owning a dog” or “your too young you don’t know anything” one vet finally listened to me and performed x-rays, her x-ray results showed she has bilateral luxating patella’s in her back legs and arthritis on her right hip. Tilly has been showing multiple

signs of depression as she can no longer do the things she loves such as walks, running , chasing birds ect due to her back legs. Tilly needs urgent surgery to help fix her legs before it’s too late and they have to be amputated, the estimate cost for the whole condition including x-rays, CT scans and a major surgery is £7000, i’m working 3 jobs to try raise the money to help her. Please may you help me give Tilly what she needs and deserves so she can have a new lease of life and be a happy little dog again x
