I can hardly wait to try our Calm, I have a service dog and love to shoot at a range. I have a small dog too that is bothered by thunderstorms and fireworks. What I’m really excited about is the electronic ears for dogs. They would be best for my Ryu. Keep in touch as you work on these, I’m very interested and when I get my first pair I will send you the results on how they work with Ryu.
