Kela and Perthes

Kela has been limping the last couple of weeks. We took her to the doctor to get x-rays and it turns out that she has Legg-Calve-Perthes Disease (LCPD). Virtually, her ball in her hip is deteriorating. Her Ped said to lay off of it and don't put weight on the leg. This would give her time to heal. However, after she saw a Specialist, he recommended to go on as normal so that her joints don't get stiff with arthritis. He said they could eventually do hip replacement surgery down the road, if needed...until he heard about her breathing condition (severe trachea malatia). Then he realized that surgery could be dangerous. Who knows what's going to happen. My poor little Kela. She is limping all over the place.
