Help a grieving teacher with her dog's vet bills

This is my cousin, Kristy and her dog, Cricket whom she adopted last year from the shelter and she has just been the best dog. Recently Cricket was diagnosed with a rare cancer in her leg which resulted in an amputation. Well, less than one month after the amputation, she was having some other complications and she sadly had to be put down. Of course if that wasn't bad enough, Kristy is now going to be left paying off Cricket's vet bills for the next few years. Kristy has been an amazing cousin/friend to me my whole life, especially recently when she took my two young daughters and myself into her home, no questions asked, when our whole life flipped upside-down. She is such a selfless person all around. I just want her to be able to grieve the loss of her precious Cricket without having to deal with this financial burden every month for years to come. Thank you so much friends!
