SMALL LONG LEGGED AMERICAN LAB will do good on grouse.
problem with lab is his heavy coat. heat in fall is tough on lab.
most serious hunters get 2 dogs.
1 for ducks other for grouse.
here are combos.
lab/setter
lab/brittany
lab /gsp
now as most know i have lab for everything.why because i only want 1 dog and toby is as close as i can get to the 1 dog thing.
lab will do everything well, NOT BEST but will do good.
if lab is not conditioned before season well,you will only get 1 hr of hunting grouse out of him or her.around water they will hunt ALL DAY.
heat is tough on labs.
