9. Spanish Water Dog

The Spanish Water Dog is a rustic, versatile breed historically used for herding sheep and retrieving waterfowl in the Iberian Peninsula. They possess an incredibly strong work ethic and thrive in environments where they can accompany you on long hikes or participate in canine sports.

Their single coat is distinctly wooly and curly. Unlike almost every other breed on this list, you should never brush a Spanish Water Dog. If you allow the coat to grow naturally, it will eventually separate into thick, felted cords. If you prefer a lower-maintenance routine, you can simply have a groomer shear the coat down completely a few times a year.

Bathing a corded Spanish Water Dog requires patience. You must squeeze the shampoo gently into the cords without scrubbing, as scrubbing will damage the structured locks. Rinsing takes a considerable amount of time to ensure no soap residue remains trapped near the skin.
