King Charles Spaniel

Not to be confused with the far more numerous Cavalier, the King Charles Spaniel is the smaller, domed-headed toy spaniel that took its name from Charles II's devotion to such dogs at Whitehall. It comes in four colours once shown as separate varieties, from black and tan to ruby. As a short-muzzled breed it can struggle with heat, breathing and anaesthesia, so meet a breeder's dogs and ask about heart and eye testing. Just 56 puppies were registered in 2025.
