Bhumi's ACL Surgery

Hi, my name is Sneha and I'm fundraising for my dog Bhumi to get surgery for her ACL. I rescued Bhumi and the Vet at the time said there was nothing wrong with her. After a few months, Bhumi started limping. Now she doesn't put any weight on her back legs. We got x-ray's done and found that both her ACLs are torn in her back legs, her right leg is the one in the worst condition. We consulted a Vet and they estimated the surgery to cost $7000. I have pet insurance, but they are refusing to cover the surgery and Vet bills leading up to this. There is no way I can cover this cost alone, and I am looking for donations for Bhumi's surgery. Thank you all for your support, it means the Bhumi (world) to me
