Verdict

Cavalier King Charles Spaniel has the cleaner trait edge for apartments. The structured trait data puts Cavalier King Charles Spaniel ahead on dog-friendly, kid-friendly, while Rat Terrier stands out for easier to train, more playful. 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, Cavalier King Charles Spaniel 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.
