Hi! I am a brand new member! I had a Boerboel who passed away last year due to Cancer. She was an excellent guard dog AND family protector. There were 3 times that she showed aggression towards strangers: one time she refused to allow me to walk by a neighbour's house. She suddenly stopped, stared at the guy and didn't look away as if to challenge him. Then she looked up at me and pulled me away on the leash. She did the same thing the next day. Okay, we never walked that way again! Then there was a handy man who constantly bothered me and was the type who would come right up to the door...one day after we had only had my Boerboel for about 2 weeks, there was a knock. She jumped up, growled, ran up a flight up steps faster than lightening, and jumped against the door, banging her rear against it and barking very fiercely. To my surprise, it was the handy man.He ran to his truck and never came back. I always thought he was seedy and she proved it. The third time, we were walking and passed by a house with construction workers...she began barking and lunging. Those men dropped their tools and scampered to the back of the house! She was kind and pleasant when meeting my son's friends, and was very behaved with my 2yr.old grandson. I want another Boerboel but it seems everything I read says the Cane Corso is a better guard dog....can anyone give me their experiences, knowledge, or opinions?
