Starting to look at getting a second bird dog for pheasant hunting. Currently have a 5 yr. old lab that I really like but looking at other breeds. Previous 3 dogs have been GSPs. I really value the ability to find down birds and cripples. My lab is pretty good in this regard. What breed generally would be considered the best on down birds and cripples ? I am thinking labs, springers, Drahthaar, Brittany ? or is this more of an individual dog trait not dependent on breed ?
