Make sure the Frontline+ is large enough dose for your dog, If boderline go up to next size.
When you apply the dose , take a little extra time and make sure total dose goes on skin. I start a shoulder blades and part fur and move back a little at a time , then save a little and apply to rump area. As for flea dirt , not sure on this one, I do know that Frontline+ kills after contact with skin. You could give a bath but then you would need to wait for 3 days to apply Frntline+.
