Aww I get that. This is the one I have that’s pretty quiet. https://a.co/d/0c8H2OO9 I’d practice just having it on around them and getting them to approach you with it and rewarding them the longer they stay next to you with it. My dog is a big calm weirdo, kind of dumb too which sounds bad but I swear it makes him have a high tolerance of almost everything. Shibas are dramatic but also usually smarter! So it may take time.
