Thank you 4doggiemamma! I've done a little more digging on my own and find they own quite a large equestrian outfit - lessons, training, buying, selling and horseshows among other horse related items.
 
The owner has been very open, patient and courteous with all my queries and questions about her YTs. They've been breeding YT's for a number of years. They are bred and raised in their house with the family. These current YT parents are 4 and 5 years old and have had 3 litters in past years. I've been going back and forth with emails to and from her for the last month or so and I finally have a deposit on one of her current pups. All her pups come with: Tails docked, dewclaws removed, vet checked and first shots, CKC registered, microchipped and a puppy pack of goodies. 
I'll be going to pick him up on Saturday - wish me luck!
