That can be based on selection as well. Along the way if someone chose the smarter dogs from the bunch then the smarter dogs should perpetuate.

The kicker is that the original Red Boy dogs were not known to be smart dogs. They were called dumb ol' Red Boy dogs, even tagged those first RBJ dogs as dumb ol' Jocko-Red Boy dogs.

Back then they were singularly focused and whatever they grabbed is where they stayed and usually took more than they gave. In the beginning the crosses were made to either add mouth to a Red Boy dog or add depth to hard charging/hard mouth to another family.

From there some smart ones popped up. The Red Boy dogs I dealt with never really had 'smart' as a calling card. We felt we were scratching a high percentage of the time.

We concentrated on looking for mouth. The dogs that could bite were matched and sometimes bred.

Every now and then we had some smart ones but they were usually a cross of some sort.

I am no breeder but I do believe if you select certain traits and breed for those you will in time get those traits. If you do not do anything to remove certain traits, again, thru selection, you will get those traits too.
