Meanwhile, dog breeders over the last century or two:

No, no, no. We specifically bred them with high levels of agression so they'd be more vicious and willing to fighting eachother.

Fuck pitbulls. There, I said it.

Aggression is not bred

Our Pomeranian Mix: "I would violently murder all of you in your sleep if only I had thumbs."

This is true but it's part of what makes chihuahuas awesome. My ex had a chihuahua that we raised from a puppy. We were totally nice and he was still psycho. He would attack me if I woke him up too early in the morning. I had to pick him up in a huge pillow as defense. He would go bananas trying to attack strangers but it's only because he was "defending" himself and our pack. The worst part of breaking up is missing that dude. Awesome dog.

Also lots of chihuahuas are totally chill.

Yeah those little rat dogs got it in for everyone

In a hypothetical situation where every dog breed is banned except for Chihuahuas, would the amount of deadly dog attacks be:

• More
• Less
• Equal

If dog breeds weren't a factor, the correct answer could only be "equal". But nobody in their right mind would make that claim.

Thus breed is a factor.
