Thanks for the info and that link, MaxaLisa--I'll read it more thoroughly tomorrow. Ridge went in for her dental last Friday and her murmur had backtracked back to a grade 2. She also tested faintly positivie for Anaplasmosis--so she will
be treated with doxycycline. We think the heart disease pre-dated the Anaplasmosis but we want to nip it in the bud before the Anaplasmosis causes any complications. She's already on an omega-3/-6 blend (Lipiderm) but I'll look into the HA, as well.
