If you’re looking for a gentle giant to protect the family check out Newfoundland. This breed is overall easy going- they are patient, gentle and calm. They do love activities though. Let them enjoy a nice swim every now and then or bring them on your daily walks.
The Dogue de Bordeaux is said to be one of the most loyal breeds, loving to be as close as possible to their owners. Don’t romanticize that too much though. As cute as that is, it can also become a problem when people that they don’t know stop by the house.
