Was surprised to find this……I got the NuWave for Christmas. When we set it up, the Pomeranian got scared to death!(normally she’s a vicious killer attack guard Pomeranian)…. Seriously she ran into the far corner of the house and hid in the walk in shower. Totally freaked out. Since that time the 2 times we’ve used the NuWave on the back porch, with doors closed, she still shakes and runs scared. Who’d have thought! I’ve not seen anything else on the net about this…….will keep an eye open…
