Baxter is super sensitive to the sound of gunshots, which is a bit of a struggle for us since we live on a hunting ranch. This app gave me a way to control the volume of the prerecorded rifle and shotgun sounds so that it was right at his threshold and then allowed me to play the sound as often as I wanted at that level so I could reward him for reacting appropriately. After about two weeks of doing this semi-regularly and slowly increasing the volume, I’ve definitely noticed a difference in how he reacts to real life gunshots. Instead of shaking and cowering he will come close and look to me (since he is so used to getting treats when he hears that sound). He’s definitely still nervous, but he isn’t shutting down.
