Sounds like gnats. If you are in an area with gnats, it is a grin and bear it mutual existence. ETA: The gnats dont hurt anything. They just land on whatever body orifice has some fluid/dampness and drink. But, I just had a brilliant idea. Try rubbing a small amount of Avon Skin So Soft on forehead, ears, down spine and over tail. See if that wont mask your dogs secretion odors that attract the gnats. Works for biting flies and mosquitoes.
