What are these small black specks? This is a zoomed in photo of my puppys groin area. We just got him and he is a 4 month old pitbull/boxer mix. Is it flea eggs? If so i gave him a flea/tick/larvae treatment a few days ago so could they be dead and just not coming off or should i give him another treatment (the kind you put on their shoulder blades, is it ok to retreat so soon?). The specks do not wipe off easily they seem like black heads bc i can get some of them off by lifting skin up an wiping roughly. Please no obvious answers like take him to the vet, he is going to the vet soon just not within the next week or two. Also, it doesn't seem to be bothering him no itching or biting or licking.
