there were but 3 this AM. I'm sold...Nexgard monthly Flea and Tic works to combat Demodex. He's looking much better after 30 days...His fur is just starting to come back. If you have a Demodex dog (one with a weak immune system) Nexgard may be the answer. Now for us to figure out how often to dose(every 1, 2, 3, 4 months???)...if he even needs any pulsing.
