An ancient breed, “mastinos” are stout, watchful guardians with a gentle, almost cuddly nature. I’m very loyal but wary with strangers and somewhat tolerant of other dogs. I’m good with kids but my size should be considered, especially with little ones. I’m more elegant and noble—sometimes even shy—than playful clown. I will stick to my owners like glue
I’m a massive, lumbering animal, so you won’t see me winning any sprint races. A long ambling walk each day will meet my activity needs, but use caution in hot weather. Obedience training and early socialization are a must—puppy behaviors can be dangerous when I am fully grown. But do be prepared for some stubbornness. I can be a lot to manage for new dog owners and can become destructive when left alone. I’m a frequent drooler and a messy eater—I can chow down 8 to 10 cups of food per day!—and I frequently pass gas. (Sorry about that.)
My velvety coat and thick, loose skin does require extra care. Weekly brushing with a bristle brush will control the hair, and my wrinkles should occasionally be wiped with a damp cloth and dried to avoid infection. My coloring can be solid gray, black, mahogany, or tawny, or subtle tan brindle stripes. I’m an imposing figure at 24 to 29 inches tall and 120 to 200 pounds.
Common to very large breeds, I have a fairly short life span of 8 to 10 years. Health issues to watch for include hip and elbow dysplasia, cardiomyopathy, cleft palate, and eye and skin problems.
