My Black lab got stung as a pup when he snapped a bee.. his face swelled up, lips all puffy and his nose ran.. took him three days to return to normal.. he has been with me in the bee yards every day, from that day to this and as far as I know has never snapped another bee and has not been stung again.. though when the bees get riled if I have to work them more than usual, he retires to the deck about thirty yards away to watch. yeah, he is black, walks among the bees on a daily basis and more or less ignores them... Unless of course, i cut out comb that has honey in it, thats a whole nother story....
