Darwin is a puppy with the energy and wide-eyed curiosity most expect from a Mastiff mix. Like any young dog, he’ll need someone willing to keep up with frequent feedings, trips outside, and plenty of socializing. Raising a puppy demands time, patience, and a willingness to guide him through the basics—house training, chewing urges, and the art of being a good housemate. If you have room for a young, active dog and can put in the work now, the reward is a loyal companion for years ahead. Darwin is waiting for his person in Ann Arbor, MI.
