    A very lovely dog good with most adults and kids, might take time to be comfortable around strangers, loves walks is trained to go outside for the bathroom, she love blankets to sleep on, not good with other dog so I would only have her if you don't have dogs and she okay with cats if the cat is friendly, she is a little fussy so she prefers tinned meat mixed with biscuits

Frequently Asked Questions

  • An adult Mastiff costs around £100. This is the average price of the Mastiff itself and other costs involved include vet bills and supplies, dog food, treats and toys.

  • Adult Mastiffs are often available through three main channels: Retiring Breeders (who may rehome a dogs after its breeding career), Private Rehoming due to lifestyle changes, and Breed-Specific Rescues. When browsing our adult listings, look for 'KC Registered' or 'Health Tested' tags. Unlike puppiess, adult dogss should be assessed for their behavior around children, other pets, and their ability to be left alone, as these are the most common reasons for adult rehoming.

  • 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.
