Verdict

Shih Tzu has the cleaner trait edge for families. The structured trait data puts Shih Tzu ahead on sheds less, dog-friendly, 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.
