I would give coconut oil! It is the absolute best anti-inflamatory, supports the immune system, and helps with IBD issues! I use CocoTherapy -- USDA Organic and human grade oil (
www.cocotherapy.com). Check out thier testimonials page!
Crazy story --- I know the benefits are amazing for humans too, so I started taking CocoTherapy coconut oil for myself. I have BAD knees, and after several weeks of taking it, I SWEAR my knees stopped hurting. I know I've heard similar stories like this. (check out the more reviews here:

One of my yorkies had bad patellas and would sometime limp. Since taking coconut oil regulary she totally doesn't limp anymore!
