Which one should you choose?
These two sit at opposite ends of both size and energy. The Water Dog's fishing-boat heritage left it with a genuine need for vigorous daily exercise and mental stimulation, while the Great Pyrenees is a giant, low-energy guardian breed content with a shorter walk and long stretches of calm watchfulness. Obedience training goes far more smoothly with the eager, quick-to-learn Water Dog, since the Pyrenees was bred to make its own calls rather than defer to a handler. Coat care is demanding for both, just for different reasons: the Water Dog's curly coat needs regular clipping despite barely shedding, while the Pyrenees sheds heavily and needs frequent brushing to match. Nighttime barking is far more likely from the Pyrenees than the Water Dog. An athletic, highly trainable companion points toward the Water Dog; a self-directed property guardian points toward the Pyrenees.
Whichever breed fits your life, consider adoption or breed-specific rescue first — many purebred and mixed-breed dogs and cats are already waiting for homes.
