Went out this weekend for opening weekend for Kansas. Having a good morning, not seeing to many birds but dog was working the field perfectly. Then we ran into some cows on the wiha we were at and they spooked the dog. He stopped hunting wouldn't range that far ahead was just acting differently. We noticed this and went to put him back in the car and a covey flushed. We shot st the covey and continued to walk to the car to put the dog in his kennel. A single flushed way ahead but this time the dog came running back to me. He was introduced to a gun by going 22 far away then gradually increase then 20 gauge far away then gradually increased then 12 gauge far away and gradually increased then 1 shot with a 20 gauge and another with a 12 gauge then 2 with a 12 gauge And a 20 gauge then eventually 3 with a 12 gauge. We've also shot quail and pigeons over him before. My concern is if this outing with the cows made him gunshy and what do I do now to make sure he still loves birds, a couple bump and chase sessions or what?
