On Friday it will be yorkies only for the Bluebonnet Specialty. On Saturday and Sunday when the Toy Club has their shows all the breeds that are in the Toy Group will be showing. You can click on the link provided earlier and scroll down the page and you will see the show times.
Page 3 shows the time of the yorkies on Friday. The sweeps starts at 1 p.m. and the regular judging starts at 1:30.
Here is a link with more information about the location of the show:
Convention Center and Exhibit hall in Mesquite, TX.
I don't know if there will be a admission fee. Most small shows do not charge one. I would recommend buying a catalog before the show starts. It makes it so much easier to follow the show and to see who is in the ring.
It is not normally recommended to take unentered dogs but some people do. Just remember that it will probably take a couple of hours just for the yorkie judging and it is more relaxing if you are not having to hold a dog.
