I find it depressing that even the anchor/voice over used the term teacup.
I fully admit one of the reasons I was interested in the yorkie breed was that they would be able to travel with me on the plane. I previously had a 135 lb bullmastiff, and our vacations were limited to places we could drive and bring him along! That being said, I can't imagine having a dog that did nothing but hang out in a carrier. It depresses me to even think about it, and I will admit when I have been around SOME smaller yorkies they had no interest in doing anything but standing in their bag and shaking. I don't know if the owner never properly socialized them because they were a "purse puppy" or what, but I hate to see dogs who don't get to be dogs first, no matter what their size is.
