5Based on our internal marketplace analysis from the last 6 months, a Mastiff puppy typically costs between £450 and £650, with an average price of £550. Note that premium prices usually reflect Kennel Club (KC) registration and litters from parents with verified health tests, such as hip and eye scores, which we strongly recommend for health security.

You can find Mastiffs through our localized search, which filters for licensed and Kennel Club Assured Breeders in and around the Dungannon area. Under UK law, any breeder producing three or more litters a year must hold a local council license. We recommend always visiting the puppy at the breeder's home to view the license and observe the mother (Dam) interacting with the litter to ensure high welfare standards.
Key things include health checks, vaccinations, pedigree documents, breeder reputation, and the puppy's temperament. Our site features detailed adverts and breeder profiles to help you make an informed decision. Read our Mastiff Buyers Guide for more information.
Licensed breeders meet high standards for animal welfare and breeding ethics. mastiff-owners.co.uk highlights licensed breeders so you can trust you're getting a well-cared-for puppy.
