Surgery For Bandit

My 8 year old dog Bandit has been unable to use or bare weight on her hind leg for the last week. I was able to scrounge a portion of the fees to get an exam and xrays done. Come to find out she she is in need of a $2,000 surgery in order for her to not only use it properly, but to avoid inflicting any further damage. She is diagnosed with high Grade 3 Luxating Patella which is basically a dislocated knee cap. This happens due to age and bone deterioration. I dont have anything close to the funds I would need in order to get this surgery done for her, but it is the only option for her to feel okay again. It's hard for me to even be asking for help like this and literally anything is appreciated. I just want my babe to feel better as soon as possible <3
