I bought it to help our 2 adult cats get on better with our 6 month old cockapoo who would usually chase and pester the cats. The dog definitely isn’t pestering as much and the cats aren’t reacting to him which helps the situation.

I also bought it to stop the dog excited peeing when visitors came. He still wees a little but a lot less than before.

I’m giving it 4/5 because it works but I can still smell it and it’s not very nice. Albeit you have to be right next to the plug to smell it.
