My late black lab, katie scarlett was about to go through some very expensive authritis treatment at the vets, when one day while chasing the ball into the brier thicket, she got into a hornets nest.
There were hundreds on her. I got them off by throwing the ball into the lake, which she would chase.
From that day forward, her authritis never bothered her again.
Ask any beekeeper. We NEVER have arthritis, so long as we get stung a few times while managing the hives. There's something in the bee venom that dissolves the calcium deposits in the joints. My dad would get tagged pretty regularly once we got a hive of the little mean black native bees -- and the crackling and creaking in his shoulder joints disappeared completely.
