Our older dog recently passed, leaving our 6 year old dog lonely. As a result she was afraid to be left home alone and would bark and howl when we left her alone. We have an internet camera we are able to monitor her on, and we was heartbroken hearing her when we left her and was considering dog sitters etc as was no nice at all.
We were recommended to try this and a bark collar. The bark collar was ridiculous as delivered a small shock not what she needed as it was clear she was needing companionship. We almost resorted to purchasing another dog to keep her company.
So we plugged the diffuser in and within minutes she was much calmer and now when left there is minimal barking and NO howling it’s like we have a different dog.
