Alentejo Mastiff, Portuguese Mastiff, Mutt of Alentejo


The Alentejo Mastiff is a large, powerful dog of rustic appearance. He has a bear-like head with a sober expression, a long, curving tail and a medium length, straight, dense coat that comes in a variety of colors.

As with all very large dogs, they are not the dogs for beginners. Dogs of this size and type have the potential to be a danger to others if not well socialized at an early age, and are recommended only for the experienced dog handler who has the time to socialize and train the dog. This Mountain dog matures slowly, is very independent, and often does not respond to traditional force methods of dog obedience training. They are extremely territorial and will protect the sheep, households, and families they feel were placed under their protection. They are not aggressive but protective and are said to get along quite well with children.
