Without being able to perform a close physical exam or view an image, it's hard to say for sure what these might be. Some dogs will have black skin pigmentation in this area that can appear as black specks, especially if they have a history of allergies or itching in this area. I would recommend having this examined by a vet to be safe - it may not be anything concerning, but it may also be a skin infection of some kind or even early signs of a skin tumor such as a [melanoma](https://www.petcoach.co/dog/condition/malignant-melanoma/). Your vet can take a look and let you know if it is a cause for concern or not.

    This is a black mass that should very definitely be examined by your veterinarian, This could very likely be a melanoma or similar cancerous mass and may need to be removed. Your vet will likely do a fine needle biopsy to either send in to a lab or examine under the microscope to see whether it is cancerous, Please do not wait long to make an appointment with your veterinarian, This could, of course also be a benign growth, however it is not possible to determine whether it is benign or malign by way of a photo.

    Thanks for using Petco Pet Education Center, formerly Petcoach! Given that no diagnosis has been reached, I think at this point it is crucial to obtain a biopsy or at least a fine needle aspirate of this. This could in theory be a growth in that region or it could even be a normal pigmentation change. I recommend that you discuss with your veterinarian further diagnostics like a biopsy. Good luck and have a great day!
