This is amazing. Have you learned how to groom a show coat? I know that is a major hurdle when dealing with the long haired show dog. All that wrapping.
I grew up helping my relatives that were into showing dogs but they did not breed Yorkies or any small dogs. I learned enough about the business to know I was not cut out for it. Later I decided to show Himalayan cats and that was an experience in itself. A lot of work but a lot of love as well. But showing both cats and dogs can be a high competition "hobby." There are people that want to win at all costs. There are also some very fine people who do their best for the breed. It takes a while to distinguish who is who.
It sounds like you have a great mentor so I hope you stick close to her and learn all you can. Best of wishes to your and your show girl!
