I don't have any personal experience w/invisible fence but my brother uses them… he has a lab mix and a frenchie. Sometimes if the lab sees something he "REALLY" wants her will jump the fence and take the shock… like a cat or squirrel. I would be wary of someone stealing my bully personally.

RIP Wellie, Bella, Winston & Roxie
Im not a fan of anything with " shock " as it cant be good for them so maybe put a normal fence

Rest In Peace Winston xxx
