Why do you say the Guerrero’s are involved in dog fighting?
They named him scar face. My neighbor named his Akida, Cujo. It bit the hell out of him and had to be destroyed.
Some people raise their dogs to be aggressive and NOT go into a pit. One way you can tell is by what they name their dog.
I have raised a number of puppies. I immediately correct bad behavior and I have never had a dog that was aggressive toward family and friends. They bark at strangers in the street, mailman and others who ring the bell and that’s about it. Once I talk to someone in a friendly tone they stop barking.
