The White Sully is a breed created by a young man, Grant Sullens from West Pont, California; back in the 70's.
They were Very Large, and somewhat aggressive... holding their own against local cats and dogs... This is why I am in search for them (if they still exist); I am tired of losing my Roosters to hungry predators... it's time to "turn the tables" so to speak.
Trivia: West Point, CA is a small foothill community about 40 miles from my home here in Herald, CA. Grant went to Calaveras High School with my brother... So, I sort of have a vested interest in finding this breed if possible.
