Interesting and now that you mention it I remember when Cali was in Service Dog school they exposed the dogs to that sound and they did it over and doves because many were not fond of it. It didn’t affect Cali much but some dogs really had some trouble with it. They did record it and use it over and over at various degrees of loudness to those who were not too fond of it. They used immersion techniques a lot at the school. Maybe that would help.
