Welcome... I think that it is great that you are researching and learning before you actually get a yorkie

Good luck on your search for a new baby.
My two are in kind of a mix of long and short cut

but I blow them completely dry after every bath. When Copper was cut shorter all over I still did this. They really get cold easy, even in the summer, so I make sure they are nice and dry. In the winter, because it can get so chilly here I will put a little shirt or PJ's on them after they are dry, until they have warmed up completely.
As far a products go, it is really going to depend on the coat type of your yorkie as to what works the best. I use different product on both of mine. I personally really like Coat Handlers products, petsilk, minksheen, and CC's Ice on Ice. I am sure other people will have a whole different list that works best for them
