"Big dogs with fluffy hair" is a broad term used to describe a group of large dog breeds with thick, soft coats. These breeds are often characterized by their gentle and friendly personalities, making them popular choices for families with children. Some of the most well-known breeds that fall into this category include the Newfoundland, the Bernese Mountain Dog, and the Great Pyrenees.
The thick, fluffy coats of these dogs provide them with insulation from the cold, making them well-suited for living in colder climates. Their coats also help to protect them from dirt and debris, making them relatively low-maintenance in terms of grooming.
