Indirectly, I can attest to the truth in this. Our 10+ year old heeler/husky mix was really struggling with both obsessively licking her paws (neurotic) and early stages of a collapsing trachea.

A good friend has a dispensary, and suggested we try very low amounts of RSO for a while... after about two months, not only is the neurosis gone, the frequent hacking (associated with the trachea) gone... but she's also behaving like a much younger dog, presumably because she also had some arthritis pain.
