Does anyone know of any other bugs besides fleas,ticks or bed bugs that get on dogs? My dog was chewing at her front legs.When I checked her out,there were bunches of tiny blackish bugs all over her leg. I pick one or two off and they are sort of hard, not a flea, bigger than a flea. I sprayed some over the counter flea and tick spray on her. That seemed to kill some of them. There were so many of them. What are these things? She is an inside/outside dog. I live in the country so I just let her out as she needs to go.
