Quick verdict

Both are gentle, affectionate British spaniels that are excellent with children, but the Cavalier King Charles Spaniel is a true toy lapdog (5.4 to 8.2 kg) with moderate energy that settles happily after a daily walk, while the Cocker Spaniel is a larger small-to-medium sporting dog (9 to 14 kg) with moderate-to-high energy that wants real outdoor play and retrieving. The single biggest difference is exercise and size: the Cavalier suits a calmer, more flexible lifestyle, while the Cocker needs more activity to stay content. The Cavalier also carries a notable inherited heart disease risk, whereas the Cocker's main upkeep is its coat and infection-prone ears.
