I wouldn’t consider a springer in the same class as say a lab when it comes to flushing, springers are light years ahead same with finding dead birds.
Not my idea of a grouse dog though.
That is comical... I have hunted three species of grouse, pheasants, woodcock, snipe and huns for 40 years with springers, and shot quite literally thousands of game birds over them, but you would not consider them grouse dogs... lol.
