Cookies luxating patella surgery

My dog is a chihuahua only 1 year old. He was having problems walking and I noticed it was getting worse cause he would cry when going up the stairs and his back left leg position was strange. He would not walk on his left leg and always had it up. He would limp and yelp from time to time and it was heartbreaking. Took him to the vet and they said his knee pops out of the joint and His condition is called luxating patella. Eventually the situation will get worse if not treated and as he gets older. He cannot go up the stairs by himself as his leg pops out the joint everytime he does so causing him discomfort and pain. We gave him medication that cost alittle over $120 to help with bone and joint development and with his pain discomfort but the situation did not get any better and now Surgery is needed but this procedure is $1000 they are asking as they have to give numerous medications and take blood as well. I have alittle put away but is hard to manage with my newborn daughter and really would appreciate the help! Any little bit helps, even $2, because it's the thought that counts !
