A list of over 100 pit bull bloodlines is available at Dogbreedinfo.com. Breeders from the American Pit Bull Registry also have extensive knowledge of pit bull bloodlines.
The bloodline is basically the family tree of the pit bull. The name of the bloodline is often derived from a kennel or even the name of a specific dog. The bloodline reveals positive characteristics about the individual dog’s temperament. This is especially important among pit bull bloodlines because of the reputation they have for violent and unpredictable behavior.
The website for the National Dog Breeder’s Council of South Africa also has a list of the most popular pit bull bloodlines.
