It's important to remember that any puppy must be microchipped before being sold by law.

Although not illegal to sell younger, it is also Highly recommended that a puppy does not leave their mother or siblings before being at least 8 weeks old. Generally, 8-12 weeks old is considered the best age to buy or sell a puppy.

Frequently Asked Questions

  • Based on our internal marketplace analysis from the last 6 months, a Mastiff puppy typically costs between £550 and £850, with an average price of £700.

  • You can find Mastiffs through our localized search, which filters for licensed and Kennel Club Assured Breeders in and around the Buckinghamshire 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.
