Welcome to Five B Ranch. We are proud to be the only breeder of the American Mastiff in the state of Texas approved by the American Mastiff Breeders Council. We are located in Terrell, Texas - about 50 miles east of Dallas.
Unfortunately, we have had to retire our one and only stud, Bosco. We will be taking a break from breeding while we rebuild our breeding program. We will not be accepting applications for pups until further notice.
