I am a yorkie person, through and through!
Growing up, we only had outside dogs and when I left school, I was in a residence at varsity. I wasn't allowed to have pets for two years and I really missed having a pet to cuddle with. So, when I moved into my own place, I got Cash (four years old now).
I've looked at many other breeds and I entertained the possibility of having a Springer spaniel, golden retriever and a shetland sheepdog. But when it came down to it, I got another Yorkie, June.
My third one... Orio is a Biewer a la Pom Pon because my mentor breeds an excellent line. She started out as my Yorkie mentor as she has both, but her Biewer line is the stuff of champions (we can't compete here yet).
I'd love to get another breed, but I know my next dog will be either a Biewer or a Yorkie
