My 1½ years aged, weight 15-18 KG male Indian breed pet dog's hind legs have become too weak to walk and even can't balance it for last 2 days. As he is unable to put his full weight in the legs, he can't even have his food by his own. Hiccups are being repeated continuously. So, we are not able to understand what has happened to him suddenly! So requesting you to please tell what should we do and if possible please prescribe the medicines too.
