This medium-sized breed is exceptionally intelligent and very lively. These very dogs are devoted to their owners and will steadfastly work to protect whatever livestock or property they are given. As such, Portuguese Sheepdogs can be distrustful of strangers.
They are reminiscent of monkeys in attitude and appearance, which has earned them the nickname “monkey dog" in their native country. They are popular for the way they keep livestock in the fields and bring back any animals that stray too far.
