I found this site when I first set out researching yorkies about a year ago, bookmarked it then forgot all about it!LOL! Theres even a forum although it does'nt get alot of use at the moment!
There are some nice products including home baked treats and the prices are fairly reasonable too. I thought I'd let you all know about it (if you don't already)
