Poor Princess! It's important to determine why this is happening in order to be able to treat it effectively. Muscle atrophy in the rear legs can occur due to arthritis, neurologic disease, an injury of some kind, or a metabolic disorder such as diabetes or hyperthyroidism. I would recommend taking Princess to the vet for an exam - he/she can do x-rays, blood work, or other testing if needed to help determine what is causing the muscle loss. Many of these issues are treatable once a diagnosis is made.
