This is rarely mentioned, but for those who live close to large cities, it is a very viable option.
Step 1
www.akc.org Go to Events and Search by State and you will see all the dog shows coming up in your area for 12 months.
Step 2 Go to
www.infodog.com something called a Judging Schedule is posted ~2wks before the show date. There you will find out how many Yorkies are entered, and you can see the dogs in the ring.
*Note
www.ytca.org wil showcase what they Call Roving Specialities, and this will be where you get to see the largest number of Yorkies in a show. Now they may not occur in a city close to you, but it is worth checking out.
Also Austin is a large enough city, that often times cities have something called All about Pet shows. Or Pet Exhibition, Many times the clubs will rent a booth to educate the public about their breed, and may have some Yorkies attending.
