So, she does or doesn't have the disease?
My Brea had the surgery and came through it just fine. She is still healing and hasn't regained full use of her leg yet, but that takes time. She only weighs 3.6 lbs, so I was a bit worried about the procedure myself, but there were no complications at all. I brought her home the same day.
Oh - I also have her half sister - they have the same dad and with that dog I have had no problems at all. Brea is 7 months and her sister is 1 year and 5 months.
