I e-mailed Dr. Dodds a few years ago with Eddie's results (lab recommended no treatment) but she recommended a low dose of soloxine. My vet doesn't have a big ego about it and wrote me the perscription, I think Eddie's disposition evened out and his energy rose, weight dropped a bit too.
I send results after every test and she has kept the same dose, never mentioned any fee. And from everything I have ever read, "low normal" results usually mean treatment for a basenji. Dr. Dodds gave me a full explanation of her reasoning, which I showed my vet.
