Cavalier King Charles spaniel
Once the lapdog of King Charles II, it's no wonder these small pups are so affectionate and love to be held. But these spaniels are also smart and playful, making them gentle but fun pets, says the AKC.
These graceful yet fearless dogs don't need a ton of exercise, but a fenced-in yard is a good idea. They can be easily distracted and obedience training doesn't always sink in if something more interesting grabs their attention.
