I'm Becky M., the breeder behind BO-BECK Bullmastiffs located in Leavittsburg, OH. We have been breeding Bullmastiffs since 1986. Health, structure, type and, most of all, temperament are very important to us while we carefully craft our breeding program. Our litters are raised in our home in a family environment. We only breed dogs that have passed their health clearances, as we feel this helps to produce a healthy puppy with a wonderful temperament.
