Legg-Calve-Perthes Disease (LCP Disease) is a congenital (present at birth) disease. Degeneration of the bone and reduced blood supply causes the puppy to suffer from pain in his hip joint and lameness in often only one back leg. Legg-Calve-Perthes Disease (LCP Disease) usually only occurs in small dog breeds Although the cause of Legg-Calve-Perthes Disease (LCP Disease) isn’t known, recent research has come up with significant proof that there’s a genetic component involved. Legg-Calve-Perthes Disease generally occurs in small dogs between 4 to 12 months of age. Loss of blood supply to the joint interferes with normal bone and joint development with the result, lameness and wasting of the affected leg. Legg-Calve-Perthes Disease affects both male and female dogs, but male dogs are four times as likely to develop the disease as female dogs. Signs. In the early stages, your dog will experience pain when he extends his hip joint while exercising or being examined by the vet. He’ll also have a severe limp and as the disease progresses will refuse to use or put any weight on the affected leg. Once the disease has become more advanced, he will suffer a visible shortening of the affected leg. Treatment. Surgery is the preferred method of treatment for Legg-Calve-Perthes Disease. Post-surgery physio will help and exercises such as swimming are encouraged to rebuild leg muscles. Copyright Pomeranian.Org. All Rights Reserved.
