An old college buddy has a springer spaniel and he shares it's the best bird dog he has ever had. Just another breed to consider. Here's some additional info I located for you. Good luck and best wishes in the search and let us know what route you ended up going?

English springer spaniel
Don’t let their small size and sweet disposition fool you -- these dogs make excellent hunters. They are known for their high energy, which sustains them through long hunts, and their ability to adapt to a variety of terrain. They have a gentle grip, which is perfect for retrieving birds. As the name suggests, they typically track prey and “spring” to scare the birds out for the hunter to shoot. They are eager to please and make a great family companion.

I don't think they use springer spaniels for waterfowl they are used for upland game fowl.
