we live in a no fence neighborhood. we have had an invisible fence for years with our boxers and have never had an issue. I will not start working with our bulldog until he is around 5 months(14 weeks now) but I am wondering if anyone has found them a bit more difficult to train on the fence. I have a lot of issues trying to get him to walk down the driveway already for a walk(once he hits the street he is ok) so I am a bit concerned how the fence will go.
