Mateus is a Fila Brasileiro, also known as a Brazilian Mastiff. He is now two years old and 184 pounds. He is a very energetic, loyal, and sometimes a hardheaded guy. He thinks he is a lap dog, but I beg to differ! His favorite things to do are love and protect his family, take long walks, "go bye bye", pass gas, and slobber on everything! You can't help but love him!
