Taka has been limping for about a week only when he gets up from a nap or tries to jump, I decided to finally take him to the vet today to see whats going on (after trying to find a vet here in Japan with the language barrier) and....He has Aseptic Necrosis of the Femoral Head aka Legg-Calve-Perthes Disease! This makes me so sad to know he's hurting and there is no treatment to help my little guy except pain meds, there is no cure for it especially since he is only 8m old and can't have surgery. Now he has a soft spot the size of a dime and this! I feel so bad for him

The only thing I know to do is to let the breeder know so he/she doesn't breed the parents again.
Does anyone know anything about this disease? and if its ok for him to still be jumping up and down on the couch/bed? I'm thinking no but just asking.
