New dog, 6 year old Cocker, told he howls when you leave him, which he did for three hours.
Been using the diffuser on permanently and with the aid of smooth radio and a chew he happily stays in his bed whole time I'm out!
Before (we have a camera) he would bark a lot, then pass constantly, looking at door.
He even now sleeps downstairs with our other dog, and stays in his bed all night!
Picture with two dogs shows him waiting by door, I put his bed close to door and that wouldn't settle him, even the other dog tried to sit with him and calm him.
Other picture shows how he now is happy in his bed when I'm out and not whining,howling,pacing...
