I have a 3 yr old Munsterlander - if you don't know the breed they look and act like giant spaniels, completely hyper and mental but the size of an Alsatian
Its taken a bit for him to get used to fishing but he does now recognises whats happening and just lies down and sunbathes while I get on with it unless I go too far up the bank away from him. I do have to tie him up though or he'd be in the water after the swans!
Don't know if he would run in to shot but I suspect he would ...haven't had a chance to get him out with shotguns yet due to massive changes in my life when he was about 1 1/2 I dont have a sgc yet

(started having babies!)
Much more of a hindrance than a help when stalking rabbits with air rifle but I still take him
