Helpful supplements you might consider include pure organic salmon oil (rich in omega-3 fatty acids), rhemania-8, CoQ10 - these can be given in rotation, so salmon oil (with a Vitamin E
canine capsule, as salmon oil depletes this vitamin in the
canine body) on day one, then rehamania-8 on day 2; then CoQ10 day three. These help boost the kidneys, improve the immune system and reduce inflammation. All quite helpful.
