Verdict
Portuguese Water Dog has the cleaner trait edge for families. The structured trait data puts Mastiff ahead on more protective, needs less grooming, while Portuguese Water Dog stands out for easier to train, more playful. Use the table as the deciding layer: families should compare child and other-dog scores, apartment renters should watch barking and energy, and allergy-conscious households should treat shedding and grooming as separate questions. On the budget model, Portuguese Water Dog is the lighter annual commitment before training, boarding, or vet surprises. Neither profile is a promise about an individual dog; breeder practices, age, training, and daily exercise still matter.
