Help Frankie get her surgery

Hi everyone, Frankie is not only my best buddy but a great little support dog who helps me get through some tough times. Now it's my turn to help her, I have taken her to the vet and unfortunately she needs an operation on both her knee joints as they pop out and will cause her a lot of pain in the future, I would appreciate any help as I couldn't imagine her in pain or having to give her away.

Thank you so much
