Historically, it is believed that dogfighters removed human-aggressive pit bulls from the gene pool. "Man biters," as dogmen referred them, were "culled" to prevent dog handlers from suffering vicious bites. However, dogmen themselves and pedigrees show a different story. As far back as 1909, George Armitage shares a story in, "Thirty Years with Fighting Dogs." He describes Caire's Rowdy as not a mere man-biter, but as a "man-eater," the most dangerous biter of all.6
In more modern years, a substantial number of champion (CH), grand champion (GR CH) and register of merit (ROM) fighting dogs carry the title of a man-biter or a man-eater. These pit bulls were championship-breeding stock, whose famed owners never for a moment considered culling the dogs. Some of the most well known dogs include: Adams' GR CH Zebo, Indian Bolio ROM, Garner's CH Chinaman ROM, Gambler's GR CH Virgil and West's CH Spade (man-eater).7
In 1974, after a series of high profile news articles written by Wayne King and published by the New York Times, the image of the ferocious fighting pit bull moved from the shadowy world of dogmen into the mainstream. This period, between 1975 and 1979, is known as the "leakage period" when the breeding of pit bulls drastically increased through gang members and drug dealers, who wanted the "toughest dog" on the block, as well as by pet pit bull breeders.8
While some dogmen of the past may have culled human-aggressive dogs to keep their stock free of man-biters, once the leakage period began, there is no evidence that similar selective pressures were maintained.9 As early as 1980, pit bull attacks begin headlining newspapers, "Another Pit Bull Attack Reported; Boy, 8 Slashed (1980)," as well as reports of pit bull owners trying to bolster the breed's "deteriorating" public image, "Pit Bull Attacks As Owners Fight Image (1980)."
