Seriously, I even ran a few trips for dog rescues where 80% of the dogs and pups I hauled were Pitts.
The problem with Pitts are the owners and yes the dog’s temperament. You raise a dog to be a bad ass it will be a bad ass. Raise a human to be a bad ass more than likely it will be a bad ass too.
If my pitts wanted to mail me or my wife they have daily chances while we sleep. I take naps at times on the sofa and it’s a battle who gets to stretch out - me or one of my dogs.
My female hates niggers and Asians. by her standards my Japanese wife isn’t Asian. Lol
Now, the chihuahua. If this dog were bigger it would be a dangerous breed. They align with one owner and fight for secondary position in the pack and this includes humans. The bite and are over all fickle and nasty temperaments.
Another thing to consider. Why do people get dogs that are aggressive? Protection of self and property. So, guns have killed more people by accidental usage than an anger dog. Let’s just destroy all aggressive guns!
