It does not appear raised or the tissue inflamed. I would monitor the area for any changes. Some pigment changes can be normal in dogs. If it starts to have an odor or seems to bother her or get bumpy then I would have it checked

    It is difficult to tell from the photos but it looks like those spots are scabs. She probably had some trauma from the mating - the male dog's nails may have scratched her? I don't think they look like anything to worry about. If they are still there in about 2 weeks, then you should have her looked at by your vet. I hope this helps. Best wishes!

    Usually flea dirt can be removed and wiping it with a wet swap it may become red in color. Although a picture could help me to define better underlying cause, this could be due to a localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any licking/scratching. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
