We have a professionally installed Dog Guard invisible fence. It was fine for my Rottie because he didn't like to be outside unless I was with him. He did his business and came right back in and if I was outside he was by my side. Plus he didn't have a high prey drive for the breed. I'm considering adding a Cane Corso to my family (my Rottie passed away over a year ago), but am concerned about its effectiveness with this breed. Some of my neighbors are successfully using their IFs with English Mastiffs and Boxers. Can you plz let me know an IF contains your dog? Thx!
