They are impossible to train. So they piss and shit where ever they please. The most worthless dog I have ever seen.
Also had the refilling food and water dog dish so I only had to feed him once a month.
He was more like a roommate. Great with the kids. Did every trick there was.
Amos finally had a rabid squirrel latch onto his back and had to be put down.

RIP Amos
I’ll say right off the bat that I can’t stand chihuahuas My best friend has one and that stupid thing pees all over her house. I told her he would be GONE!!!!
Well, what do you expect? They're Mexican, right?
We have two Chihuahuas and neither are like that....most bad dogs are due to bad owners. They are hyper for sure but you would be hard pressed to get either of them to bite short of hurting them!!!!! No one can sneak up on our house!!!
My ex said her family had one when she was a kid. It was such a nasty creature that they had to wear heavy gloves just to hold it when giving it a bath.
