Every dog owner wants his dog to be happy, strong, healthy and to live long. The majority of Mastiff specialists claim that an average Mastiff dog will live for about 10 years. But if you provide him with proper care, feeding and training he will be able to live more than 15 years such as famous female Mastiff named Kush. 

One of the reason of long life is daily exercise which is necessary for such massive, stubborn and slobbery dogs. Remember exercising a Mastiff isn't as difficult as it seems to be. They do not have an excessive energy as many of working dog breeds. Be sure your Mastiff will be happy to have two walks a day of about 20 minutes around the neighbourhood. Also their exercise can be hikes in the forest, swims in the pool or in the local lake, chasing balls, etc. Choose whatever your Mastiff likes more and enjoy your everyday activities!
