i wonder if anyone can help with advice.my friend has a springer the bitch broke her back leg at the knee ball joint 5 mths ago however she is often quite lame and picks her leg up and she seems to have less muscle in the damaged leg for obvious reasons. i know she is kept as mainly a pet so doesnt get the same sort of excercise that she should but any advice towards helping him building the leg up and any set pattern he should take with the bitch ie walking on the tarmac on the lead, diet anything that can help him myself i am not to impressed with the leg and the op cost him a grand or so i
