  • An adult Mastiff costs around £350. 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.
