RE: flushing.....help!!
I would not shoot at any birds that it flushed like that.
I plant birds in launchers and worked my dog , when he locked up on the bird I had my neice haul him back hard if he broke to flush without comand. If he broke to flush we left the bird and hunted on .We did this a few times a he figured out he had to wait or would not get to fetch the bird. In 2 days he I taught him to hold a point .
I have a lab but it should work with your shorthair Good luck
