Our 8 month old...
Our 8 month old rescue was emotionally out of control and borderline aggressive and a year of using the diffuser has helped immensely in calming his demeanour and actions.

It worked for my...
It worked for my dog who is afraid of everything, and especially our hardwood floors. I used TheraPet in my hallway and now he will walk down the hall(which has a runner) and onto the hardwood floor just fine. It's been a lifesaver and I can always tell when it runs out as my Golden will hesitate & stop before going on the hardwood floor.

It has taken longer, but it’s working
It has taken longer to have an effect on my stud dog but …. The marking in the house (yes he was housetrained and IS but it is as if he has no control. He would roll over showing submission if he had done it in the room I entered.
I also have a girl who shows her excitement by screaming when she comes out of her crate. The screaming has been reduced by over 50%.
