On 8 Nov 2007, I was wrote to Dr. Sponenberg, and asked him why the Sulphur Horses weren't listed in this article about the Colonial Spanish Horses.
Dr. Sponenberg, answered me by emailing me this information about his NEW BOOK. He,of course chastised me for citizing him for not caring about the Sulphur Horses.
This is what he said:
"The whole Colonial Spanish part of the breed list is going to be revised next year, with separate listing of the different Colonial Spanish Strains that are numerous enough to actually persist in to the future as intact strains. The Sulphur will be among those."
