Haha, I had a feeling this would be Dom.
... What?
How about he doesn't need a big pitbull or staffie because he doesn't need to overcompensate for something?
I have five dogs, four of which were rescued from being tortured to death, and three of our five are small, yet I'll gladly walk them because I don't give a shit if someone thinks "look at this pussy walking a tiny dog".
A guy that has a chihuahua has far more confidence than a guy with a big dog.
So, if anything, you just made yourselves look bad.
