Ok, so you have an unknown dog, which could be heavy on the "bulldog" and you don't really know about, and a Chinaman which is known for human aggression, and Redboy/Jocko, which I have seen both sides of since a lot of bully fellows like using them against stuff like Razors edge. In heavily inbred stuff (R/J) I have never seen HA. That explains it. I have to say that Tonedog is more accurate. The breed is extremely diverse. I have taken dogs right out of other people's yards. I have had some bark and raise hackles, but then change their mind when they realize I am not afraid. They tend to be brave until someone doesn't buy the bluff. The only problem ones were either dual registered, bully bred, ghetto bred, or Chinaman dogs, lol. This is why it pays to know your lines and types before purchasing one.
