Health is a very important topic to read up on with this breed, there is alot of health concerns that come with a giant breed dog. Proper feeding can and will help for a happy life for your new companion. Be forewarned this breed will eat you out of house and home! They weigh as much as most adults, and will eat more then a teenage boy! This is a breed that needs to use its mind and body, yes it would love to be a couch potato as well but will eat the couch if left without any other means to expel energy. If you are looking to leave a dog outside all the time and not socialize, or train THIS IS NOT THE RIGHT DOG! It is highly recommended to have a trainer work with you and your mastini.
