I also have problems with my dog that has fleas, ticks and other parasites. I've found a reddish-black small little bug on my dog before, 4 times! And i kill them. My dog normally scratches under its body (somewhere at the side), around its neck and sometimes at the side on the body. But when i feel at the place it scratches, I just don't seem to find any parasite?

But i've bought 2 types of flea,ticks,parasites solution to kill them and so far it has been working but still some parasites are left.
