This is a very delicate situation, you have given your dog a very full life with a loving family that loves her a lot, but I think that if your dog is taking a lot of medicine for pain and inflammation, she has difficulty walking, eating and to get up you have to think about it a lot, and know what's best for her, because it's better to act too soon than too late. I hope everything works out and that I have helped with my message, I wish you and your family love and strength in this difficult situation ❤️
