I have one of the most formidable dogs on the planet - a 165lb APBT with papers from a long time ( 30+ year ) breeder! He was socialized as good as any dog. I have never lived in a house without one, or two including part wolves - so I know a little about them. Here is my take:
Dogs since fear, and identify it with a threat. I have had black women flag me over to see my dog - to take pictures, and walk right up to the car with his big head sticking out the window without reservation, and pet, and hug him - more than once! Black males on the other hand are usually petrified of him, and quickly vacate his proximity. I feel that most of these black males are predators, and predators can sense formability, and the fight or flight mode kicks in. I also feel that these vitimizers walk around with the sense that what goes around comes around, and they fear each day that it maybe the day of reckoning - so they flee! I can also easily tell that blacks are not as developed mentally as whites, or other races - so they have a more reflexive response. Most any predator will instinktively flee the more formattable one
without hesitation.
Just last week I was in a puppy store to purchase one. The store had many black males in it - who all vacated it immediately upon our arival. My dog is 7.75, years old. I have had many black males ask me the usual: what kind of dog, how much does he weight, what do you feed him etc. I always ask them if they would like to pet him - I have had 2, that took the offer, and I have him in public every week, and I live outside of DC!
