I had a young dog who had severe arthritus, when it was bad the vet put her on metacalm but she still yelped sometimes.

I then heard about manuka honey with added bee venom. I can honestly say within 25mins of her having a bit she was a different dog.

I got it on line from a company called nectar ease. You have to get the one with "added bee venom" as that bit works as a good pain killer. But if you do order it just give them a tiny tiny bit to start as like humans some people or animals can react to been venom.

I am nothing to do with this website, but have personally seen manuka honey work wonders. If i ever suffered from arthritus i wouldn't hesitate.
