I'm Carol S., the breeder behind Sims English Mastiffs located in Inverness, FL. We take pride in our Mastiffs and when we do have a litter we strive to produce to meet AKC/OFA standards. We research our stud's pedigrees prior to breeding to look at getting all the strengths of each canine being bred to ensure we are breeding for soundness, structure, temperament, and health.
