Aww, so sad to read this After we rescued our Joey we found out she had Hip Dysplasia as well, I was so heartbroken. Our wet preformed Femoral head removal (think that is what he said...) and it was a success She's now doing great, the recovery took a while but she could manage herself during the whole time and even walk shorter distances. Joey was 4 when she had her first surgery, it was only about 3 month after we got her. The second hip we did one year later so the first one could heal properly.
Your baby is still young, I hope you'll find a way for her to be pain free. Will be thinking of you
