Verdict

Mastiff has the cleaner trait edge for apartments. The structured trait data puts Mastiff ahead on more protective, needs less grooming, while Parson Russell Terrier stands out for dog-friendly, drools less. 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, Parson Russell Terrier 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.
