...of course, the reality is that none of us know for absolute certainty that Jaws is the daddy. They were found together in a garage, but there is always the possibility that there might have been some other dog involved. But even if he is the daddy, it is still a fun project.
Part of the fun is not knowing what the pups will look like until they get here. Pitbulls can come in practically any colors, and not knowing mama's and daddy's heritage, almost anything is possible. If there is any particularly cute or original or unusual one, I would consider keeping it.
