I heard they were bred to be alarm dogs. Nothing was getting close to your camp if you had a chihuahua. That's why they never shut up, and they are so difficult to ignore. My friend from Mexico told me that - he's not a dog authority by any means, but it sounded legit to me.

Chihuahua are an old breed and I don't think we know their true history. Old breeds tend to be healthier and more compatible with humans though, as we have worked all the bugs out.

No idea. They are very good lapdogs. Our dog is actually very nice and cute but she just doesn't learn anything. T

I have agree with you half don't, I train Australian Shepherds and I can say without a doubt that positive enforcement works better then positive punishment. I have worked with 2 Chihuahuas in my lifetime, but were little pieces of shit that don't respond to anything either way.

So I guess we should clicker train our black/brown haired fat kids and the blonde skinny ones are screwed.

Seriously though, your post makes me think about how dogs/child teaching is all in what you have and psychologist (maybe news) try to apply one method to all of them. It just doesn't work, some kids need one thing and others need something else. We live in such a crazy complex world.

Probably bred to be rodent dogs.
