Papa's Bullmastiffs' Stud Service is available in the U.S. and overseas. We have frozen semen stored in Las vegas as well as the U.K., and offer live cover (natural breeding) for those close to us.  Please be aware we are very selective in the bitches we stand are males to. We will expect to see pictures of your bitch, pedigree, and proper health clearences. Papa's Bullmastiffs will try to find the stud that best compliments your bitch. We will only stand to your bitch if we feel the offspring will be an improvement to the breed!
