What's the Deal with Chihuahuas?

OK. I know these dogs are amazingly cute. They are also the dandiest fashion accessories as they can be carried in a Gucci bag. And why is it you can go into nearly any store in which no dogs are allowed, but if you have a chihuahua in your purse, no one says anything? Are they not even sure if it is a dog?
I have yet to see one as a hood ornament...well, because that would just be wrong!, but I have seen one riding in the basket of a motor cycle with a leather wind hat on. I thought the chihuahua craze would have ended shortly after Paris Hilton ended up in jail, but the phenomena continues.
I have one chihuahua art pendant in my shop, and through that I've found that "chihuahua" is a very popular keyword search. Not just popular, but they seem to have a cult-like following. Sooo, there may be more chihuahuas to come into my shop; otherwise, I'll just adore this one in the picture below. Since I can't have one, I can borrow my family members, dear Sandy. I admit...I've been taken in a bit too, by their big bulging eyes and huge pointed ears, and teensie, eensie, paws. Yeah, they are a tad irresistible.
