The law is interesting here (UK)
Under the Veterinary Surgeons' Act, only a vet. may prescribe drugs.
Only a vet. trained in their use may prescribe Bach Remedies or other Flower Remedies, herbs, homeopathy or other 'alternative'.
This means that even a highly-qualified therapist cannot legally recommend a specific alternative treatment unless they are also a vet.
Owners can research and treat their own dog (other animal) as long as it does not involve 'a veterinary procedure' (legal grey area - are any of these 'veterinary procedures?') or cause 'unnecessary suffering'.
This is criminal law and penalties are draconian.
So we can suggest you do some research in a specific area, which is what we have done
but we have to be careful what else we mention.
Personally, I'd have a really good look at Bach Remedies, and also a chat with Dorwest Herbs, whose products are licenced for veterinary use and who can legally give advice - they are very friendly and knowledgeable.
For your other question - you have PM.
