Verdict

Boston Terrier has the cleaner trait edge for families. The structured trait data puts Boston Terrier ahead on more playful, welcomes strangers, while Chihuahua stands out for needs less grooming, 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, Chihuahua 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.
