We breed for a bigger, taller bulldog that still carries that huge muscle mass and bully head. We believe that you can have all the great qualities of a bully dog in a bigger package. The Studs of Walkers American Bulldogs fit the bill and we invite you to look through our excellent line up of Stud dogs here at Walker American Bulldogs. We offer stud service on females we have sold or produced. Please contact us for more information.
