I have a 2 year old Catahoula who roams free and listens for the most part, but she has her moments when I just can't get her back to the house and it drives me nuts. I was thinking about getting an invisible fence for her, but it might just break her heart if she didn't have the run of the property when we're out there. Have you ever used an invisible fence to contain your dog? Did it drive them mad?
