Verdict

Beagle has the cleaner trait edge for families. The structured trait data puts Beagle ahead on dog-friendly, kid-friendly, while Mastiff stands out for more protective, needs less grooming. 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, Beagle 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.
