Here's the thing about "medicating" canine anxiety, whether with something natural or with something pharmaceutical: the board-certified vet behaviorists generally don't just throw meds at problems. Instead, they sometimes use them while also developing a positive program to de-sensitize the dog to its triggers, develop some coping skills, and work on behavioral modification for long-term solutions. There's some hard work involved in getting good outcomes with that approach -- success requires more than just throwing a pill at the dog!
There aren't many of these board-certified veterinary behaviorists (it requires a vet degree plus several more years of training in a residency, with successful practical application for clients, etc. to even be allowed to sit for the board exam -- the process is just like becoming a vet neurologist or ophthalmologist...years of extra work). It's sometimes hard to find one, but they often do phone consultations with vets -- so your vet could call one at the nearest state vet school and ask!
The board certified vet behaviorist whom I met with last week for a rescue foster described RX meds as helping to give us access to a mind frame where the behavioral mod work she was recommending could be more successful -- better access to the neuro-pathways to get the learning to move into long-term memory gives it a better chance to work. Anxiety can make it feel like the dog has a full "in box" and nothing is getting through -- you often can't train through that. Her hope is that RX meds are not going to be needed forever for this particular dog -- they're a bridge while we work on his rehab.
If you are considering something like CBD, you and/or your vet probably will want to read through the Consumer Lab test of CBD products (human and canine). It lives behind a paywall, but many vets buy access -- it's a site that does rigorous third-party lab testing of OTC supplements and publishes the results. Lots of CBD products don't contain what they claim, some have undeclared THC, others have no active CBD despite label claims, or not the levels advertised (some have far more, some far less). The supplement industry is like the Wild West, and this one is a new Gold Rush.
You might also want to look into (and talk to your vet about) Solliquin (an OTC supplement from Nutramax, maker of Dasaquin--a very well-regarded, research-driven company) and Calming Care probiotic (RX from the vet, from Purina's veterinary division; it's a proprietary strain with research showing it helps very modestly with anxiety).
