Ratings and reviews

Mastiffs are the best. Just make sure you can handle them. They are not mean! They just have the size and attitude to do what they want, if not trained and socialized BY or for you. Great breed! Good simulator.

This game...IS GREAT and i have a mastiff in real life his name is hunter and he looks like the Mastiff in this game i love this game so much but can you add some other dogs to play with and can you have a owner and you get treats from the owner and walk with owner and you can have a mate and have puppys that would be great.

Speechless the game is nice and the graphics are clean
