Welcome to GridIron Bullmastiffs

GridIron Bullmastiffs is a responsible breeder of Bullmastiffs located in Perrinton, Michigan.  We are located on Rainbow Lake, about 40 minutes north of Lansing, Michigan.  Our bullmastiffs are part of our family.  Our bullmastiff breedings are selectively planned and we strive to produce quality puppies sound in body, temperment, and health.

Because we live on the water, our bullmastiffs enjoy swimming and going for rides on our pontoon.   Besides lounging by the lake, they can often be seen taking walks around the neighborhood and going for rides.


We hope you enjoy our website.  As you will see, we are very proud of our bullmastiff doggie family and post lots of pictures.  We also update our site often so feel free to visit us often.
