As I've posted before, Puck has a luxating patella in his right hind leg.
The vet called it, at the time, "a mid-grade median slip." And said that "at some point if it starts to bother him, we might recommend a minor surgury."
I asked about it bothering him and what kind of surgury. The vet assured me that the condition shouldn't cause Puck any pain--not from the knee slipping in and out. He said that the surgury would go in and make the joint a little deeper so it couldn't slip out so easily.
Each time I've brought Puck in, the vet has sounded a little bit more "sure" about going for a surgury. At first it was "at some point, maybe" then it was, "probably need," then it was "that surgury should definately be considered." But he has continued to assure me that Puck shouldn't be in any pain--I'm the one that keeps bringing it up.
Because it seems to me that he is in pain. A lot of the time when you pick him up, he'll cry out. He also growls at you if you put your hand near his leg. He's obviously nervous about his whole rear end.
I told both the vet and his assistant that and they both seemed confused. They gave me some pain medicine and said that if it appears to be bothering him on some day, give him one pill. I can't even see that it helps when I give him the pill.
How many people have had to get a knee surgury for their Chis? How traumatic was it? How expensive? How long did the vet keep your dog? How long was the recovery? Was it effective? Are there any specific dangers to NOT getting the surgury? Are there any specific dangers TO getting the surgury?
They told me it would be around $350 for the surgury and they'd want to keep Puck for "at least 2 nights." I asked them if that $350 included any probable after-care costs. She said, "No, but there shouldn't be much involved in after care..." but then proceeded to list the possibility of needing pain medicine, anti-biotics, a collar to keep him from pulling out the stitches, and a host of other things.
I am really poor. I want to do what's best for my dog, but the puppy's going to need spaying soon (maybe I can put that off. Puck's nuetered and it's not as if going through heat will hurt her...right?). I have about $1,500 in credit card debt and $350 in my savings and I need to have that credit card debt paid of SOON so I can go back to school.

Cost is a consideration. But there are a lot of other considerations as well. And if putting off this surgury might cause him some sort of injury that will require a more expensive surgury, then being proactive is the best idea.
