Tucker, he was a singlton puppy with no lilttermates, no full siblings and no half siblings. That in itself makes his gene pool significant for the breed's origins. He was bred only 5 times to 4 different bitches producing singleton litters each time. Although he himself did not earn his championship, his champion get percentage was quite high with 4 champion get out of 5.
