Hi...first let me say, I'm so sorry that you're having to go thru this. My heart goes out to you and your Skeeter. My Tonka had this and the best thing for him was euthanasia. He was just 6 months old. Didn't mean it didn't hurt though.
Please read this thread as well. This is about someone else that I met while I was researching about A-A Subluxation...they had the surgery, which I was told would run me anywhere from $3,500 - $6,000 depending on how he did while under anesthesia and the time it took him to heal under their direct care.
Again, I'm so sorry.
