A good friend owns two Spotted Walkers. They are half brothers and while I'm sure she has their papers, I need to ask her.
Back in the '80's, a lady by the name of Sherry Duriga had a serious breeding program to try and raise the bar AND acceptance of Spotted Tennessee Walkers.
I became acquainted with her when I bought a Morab mare from her.
Sadly, she passed from cancer a few years back. I have no idea if her stock was disposed of before she became really sick or if the horses went into her estate.
While Spotted Walkers are not the horse judges look at, they have been in the Walking Horse gene pool from the beginning.
For example, look at three of the horses in the top row of these 1920's stallions. Tennessee Walkers - Walkers West - Pictures of Famous Tennessee Walking Horses - Ancestors-1920's
Lotsa spots there and they all seem to be in the "Allen" line
As far as Spotted Saddle Horses? Today's SSH's don't begin to resemble the Old Timey SSH's. They were short, stocky and could carry a lot of weight for their little selves.
This is what I consider a true Spotted Saddle Horse. He belonged to my friend in PA. She found him up in the Allegheny's but he was bred and born in the Manchester/McMinnville, TN area. He had a sweet heart personality, big heart and terrific work ethic.
She sold him because she is taller and the cancer meds caused her to gain a lot of weight. She was afraid he wouldn't be able to carry her, sloggin' thru mud all the time. Anyone from PA knows the ground never dries out-lollol
Anyway, if one studies the physical characteristics of this SSH, they don't bare much resemblance to the "new" SSH's that have been seriously infused with TWH blood.
