Pedigree of Ikenheel Diamonds N Dust (Dusty) Her lines can be traced back to Little Logic through Wooleston Blue Jack
"Sydney exhibitors saw Little Logic offspring, for the first time, among entrants at the Sydney Royal of 1947. These exhibits, and their sires' show record, created immediate demand for Little Logic's lineage. By the end of the 1950s, there were few Australian Cattle Dogs whelped that were not Little Logic descendants. The convergence on Little Logic continued into the next generation when Little Logic's best known son, Logic Return, also attained prominence in the show ring and popularity at stud.
The prominence of Little Logic and Logic Return in the pedigrees of modern Australian Cattle Dogs was perpetuated by Wooleston Kennels. Whelped in 1965, Wooleston Blue Jack was line bred to Little Logic and Logic Return, and Wooleston Kennels subsequently line bred to Wooleston Blue Jack, himself. For some twenty years, Wooleston supplied foundation and supplementary breeding stock to breeders in Australia, North America and Continental Europe. As a result, Wooleston Blue Jack is ancestral to most, if not all, Australian Cattle Dogs whelped since 1990 in any country." ACD Breed History Noreen Clark
