Verdict
Rat Terrier has the cleaner trait edge for families. The structured trait data puts Rat Terrier ahead on easier to train, more playful, while Cairn Terrier stands out for drools less, sheds 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, Rat 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.
