LOL.
We have a Pit and Chihuahua.
Both are love monkeys. And neither one are allowed around people they don’t know without supervision and a leash.
They are dogs, not people, and will act like dogs if we allow it.
I’m sorry, but dog owners are incredibly good at living in denial. All dogs bite, Pit Bulls kill. It’s wonderful that you have a mindmeld with your animal, I have one with my pet lion too... No really, she’s tame... come on in... What the hell are you afraid of?
If I came to your house, I would expect the chihuahua to snap more readily than the pit bull.
(No offense to your little chihuahua!)
