Dog and Possible Auto Immune Illness

Can you recommend any herb(s) for a dog who is possibly auto-immune? Everything I've come across so far, boosts the immune system.

There are many conditions that fall under the umbrella of "auto immune" disease, so it is impossible to answer your question without alot of further information. In addition, should your dog be dealing with an auto immune illness, it would be best for your and your dog to seek a consultation with a qualified practitioner in your area who has experience with both animals and herbs. Such a person may be found through the Veterinary Botanical Medicine Association (www.vbma.org).
