Born in 1937 with an inbreeding coefficient too low to measure, Attaboy had 3 littermates and 9 full siblings, none champions. Of the 9 full siblings, 7 were Colonsay dogs. From his sire, Tiny Tim of Biffin, there were 55 half siblings, two of which achieved their championship. Of his paternal half siblings 45 of the 55 carried the Colonsay prefix, so that one would assume Attaboy's sire was more valued by the Colonsay kennels than a wider variety of other Norfolk kennels at the time. Of the 7 half siblings on Attaboy's dam's side none were champions. He was bred only 3 times producing 9 get with no champion get. 7 of his 9 get carried the Colonsay prefix and 2 of the 3 breedings were to Colonsay Molly..
