I keep forgetting what popular dogs Cavaliers are in the U.K. In the U.S., they are still fairly rare and mine are usually the only ones in the dog park! Most frequent first question from strangers is to ask me what breed they are.
I agree! Most people can see that it is a "spaniel" of some sort but don't know that it is a Cavalier.
