I’m not keen on the smell but am absolutely delighted with the effect on my girl. She gets so distressed with thunder and fireworks but I plugged this straight in on Thursday when it arrived. We had a few fireworks Friday and no reaction. Tonight was much noisier due to a local display. Although she cried a bit with some loud bangs, she wasn’t panicking and panting, didn’t even react to some and relaxed enough to snooze with the addition of a little spray.
