To breed two Staffordshire bull terriers, choose a suitable mate, draw up a breeding contract with the owner of the other dog, perform prebreeding health checks on both dogs and then allow the dogs to mate. A prospective breeder should try to improve the breed with each litter.
Before breeding, learn as much as possible about the Staffordshire bull terrier. There is a certain science that comes along with breeding, and improving a particular breed requires knowledge. To a breeder, his own dog may be the best dog in the world, but breeding tends to bring out the flaws in the parents if a suitable mate is not found that will lessen or eliminate those flaws.
Both parents should be AKC registered, and health and temperament must be taken into consideration because both are hereditary traits. Once thorough health checks have been completed on both the male and female, a stud contract will need to be drawn up outlining the stud fee, and both owners should receive a signed copy.
It is always a good idea to wait until the bitch's second heat before attempting to breed. Wait until between the 10th and 14th day of a dog's heat cycle then introduce the male to the female. Mating should naturally occur as long as the female is willing to accept the male. Allow the dogs to mate every other day for a total of two or three matings.
