Other than that, a lot of the sporting breed/herding breeds would suit your needs.
german shepherds
border collies
heelers
Australian shepherds
Flat coats
Chesapeake bay retrievers
Nova scotia duck tolling retrievers
english springers
brittany spaniel
etc.
Each have slightly different traits breed-to-breed but if you look into either group I'm sure you'd find a couple you'll like.
