One of the concerns with everyone and their uncle jumping on the CBD for veterinary use bandwagon is that there is little regulation in the supplement market. When bought OTC (and even sometime when bought from a medical source) doG knows what concentration any given product actually contains.
If you go this route, I'd recommend discussing this with your veterinarian first. Especially if you are on any other medication or have any other known conditions, to ensure that there are no counterindications or negative interactions.
Yes, the CBD oil industry is booming, but there is little 'hard' research into the various products' efficacy for the variety of uses it is being touted for.
My personal stance is neither pro nor con - but I do think it important that one should be aware that there is need for much more research.
For now, I would urge owners to look up what reputable-sourced research there is out there, avoid info from potential COI industry sources, discuss CBD use with your vet in light of your individual dog, and then make an informed decision. And use the product recommended by your vet.
FYI, here is a study done on the effects of CBD on noise induced anxiety:

And one on effect on voluntary daily activity:

And another on stress and shelter dogs:

Yes, I have tried CBD oil, a product carried by my vet. It was among the 'Hail Mary passes' we turned to when trying to help the Belltie towards the end. We did not use it for anxiety so cannot comment on that, rather we tried it for pain.
It did nothing - other than empty my wallet a tad faster than usual. (But hey, it all goes to the dogs anyway...)

We are seeing the specialist in Verhaltensmedizin who is helping Robin Goodfellow tomorrow. I will ask her if there is any new research into CBD oil for anxiety or any new recommendations, and will update.
