Needed financial help for Bears Vet Bills

Update edited) it’s been months and unfortunately Bears leg isn’t getting any better. She is in a lot of pain and has to be on constant pain medicine and now her left front leg is collapsing and causing her a lot of uncomfortability. She has a vet appointment on the 25th to get her teeth cleaned which is going to cost $600 and then another next week to look at her leg to figure out what it possibly could be That is causing her so much pain and discomfort. It seems to be a fracture however it has just gotten worse and worse, and I don’t know if we need to amputate it or put her down or what would be the best most humane thing to do. This is really hard for me because she has been my best friend and constant companion for the past decade. She also still seems to have a lot of life left in her, and I would hate to have to end it because of an injury and not having the financial ability to take care of her properly. Thank you for anyone who has donated already for those who can help or share. I really appreciate you.
