Calling all Cocker, Brittany, and Springer Spaniel owners!?

When I was a child and we let our English Cocker spaniel get off-leash her nose was to the ground and she was gone. Very much like a hound. We could get her back - only when she was done her sniffing. I am wondering if American Cockers, Brittany's, and Springer Spaniels are like this as well?Do they tend to put their nose the ground and are gone? Are any of these breeds less likely to be like a hound with the nose to the ground? I've heard Brittany's put their nose the the ground and are gone. Is this true? And what about Springer Spaniels? what are they like off-leash or on a walk, are they trying to sniff the ground or do they generally have their heads up? I've done a lot of online research and can't find answers specifically to this. Hoping people with experience with these breeds will comment. Thanks!
