Amazing Difference – I bought this in an attempt to stop our 1 year old cavapoo constantly barking (often whilst looking out the windows). I wasn’t expecting it to work but thought it was worth a try. Within half an hour of it being plugged in we noticed a difference and 24 hours later it’s like we have a different dog! She hasn’t barked unnecessarily and she’s been much more relaxed.

It does have a slight smell but not unpleasant and not very noticeable.
