Jock was saved by Fitzpatrick from being drowned in a bucket for being the runt of the litter (he would ruin the litter if left with them). Jock was very loyal towards Percy, and brave. He was once enticed to fight a baboon by Seedling. He killed the baboon in the fight, due to his small, stocky build. Jock permanently lost his hearing when a kudu cow kicked him. This is attributed as one of the main reasons he died, as he could not hear Tom Barnett when he called him, and was mistakenly shot, because he was thought to be the dog killing chickens on the farm (when Jock had meanwhile already killed the other intruding dog). Jock was an English Staffordshire Bull Terrier.
