Somehow he got fleas even though we treat him for this monthly. After noticing the fleas we gave him a bath and then put on his monthly treatment. They seem to have left, but there are these black specs in his fur. After googling i discovered it is flea dirt, but i didn’t see how to get rid of it. Any advice for a fluffy long furred dog?
