I'm a little late with this! I have practiced this since I had my first bird dog in grade school. New dog owners beware of fireworks, especially a young pup. I have never seen them ruined by it, some even like it, to much! run like fools to retrieve or pounce on some, others with disinterested, but some get bothered by it, try to sly away, get to cover, or become absolutely traumatized. That would be nervous disposition, slobbering, running blindly away, tail tucked in. Most of these will be overcome, afterward, and surprisingly good results, The shy dog, will usually not carry it to the field. There are rewards in the field, minor shooting, with a different report usually return to normal. It's like the dog, who is afraid of thunderstorms, ( as you know, some are some not!) get over it in the field. I would always avoid fireworks, but if you live in a neighborhood where every kid has them ( mine!), take precautions if you can. The dog very well get over it, though I doubt never be a fireworks fan. Come to think of it, when I got birddogs, the cindered hands, black powdered aroma youth got over it to, never been my thing since, but the kids love it!
