Hi Angela I have Labs & a few yrs they got in the chicken run & went charging around & 1 ended up with a partial tear. I was adviced to cage her with very strict instructions to keep her on lead when she went out to do her business. It took ages but it was worth it & she didn`t need surgery. Twice since then, when she has been going mad she has held her leg up but other than that she is now fine & has no problems so it worked for her.
