RE: Labs for Upland game?
I would venture to make a bet that more birds are shot over labs and GSPs each year than all other breeds combined. A lab is a decent upland dog and a great retriever. They lose their advantage when hunting out west for sharptails and pheasant in open country where a big ranging dog makes the difference. For hunting marshes for pheasants though a lab is a good dog.
However, if you like style, a good springer spaniel is the prettiest rough shooting dog you will ever see.
