Gruff is a 4 month-old Neopolitan Mastiff who lives with Eddie the Hounddog (that's him in the background). Rescued from a breeder who kept him confined in a cage so long that he developed sores on the bottom of his paws, he's doing great with his new family and is recovering from his ordeal.
Gruff looks like he's going to grow up to be as large as his father, who weighed 190 pounds.
