I see quite a few but then I work at a kennel that does offer to fix those mistakes.
Those mistakes mainly caused by banging loud objects with no bird conctact. I also cringe every time I see a pup at several of the local trap and skeet ranges I go to and to hear I am "conditioning the dog!" Again no bird contact. Correct way is with a pup taht is off age that is mature enough that once the bird flushes it is distracted enough the loud bang makes no difference.
Others may see it different and so be it.
I now don't say a word as I am tired of getting bashed. Carry on.
