Back story - I started introducing gun fire to Sookie back in March, daughter would have a 22, be about 100 yds away, while Sookie and I played, moving in when she showed no reaction. After 2 to 3 sessions, Sookie had no issues. Then brought out the shotgun, again started about 100 yds out, moving in while I played with her, until she was comfortable shooting right beside her. In June, started shooting clays with our family. I took her about 50 yds out, played and continued to move in closer until she would sit or down right beside us as we were shooting clays. Did this 3 times from June thru early August. Yesterday - family out shooting clays, I again took her about 50 yds away, had her retrieving after a shot, while continuously moving in until I had her sitting at heel right next to me on a chair while I shot. Tail wagging. Did great, retrieved some bumpers towards the end after a shot. My brother-in-law and nephew then brought out there 22's to target shoot. The first shots sent Sookie under the truck. After i got her out, had my daughter shoot off a couple of shotguns, no issues. Then had my BIL shoot another 22, she tried to get away from me. Is it the "high pitched" sound that's coming from the 22 that's causing this? Or did I not do enough with the 22 back in March-April? Kind of at a loss, she does great with the guns that she'll be "hunting" with (duck and pheasant). Your input is greatly appreciated.
