Customer Question

My 6yr old yellow lab has black clay like particles enbedded around her nipples, what could this be?

Some times blackening skin like this can be an indication of a thyroid problem.
If any of the black spots look like sores that could be mammary cancer.
Alternatively if she is spending time digging in the yard it could be dirt or if she is sunbathing belly up it might be tanning.
Might even be as a result of a food allergy but usually itching is involved with that.
If they don't wash off and seem to be increasing I'd suggest a vet check to see if it could be a thyroid issue and a middle age dog like this could use a blood panel check anyhow to make sure all the organs are working well.
Labs are known to potentially have thyroid problems.

Reply to Nancy Holmes's Post: this is not a skin color ,it is like clay and you can pull them off they are long cigar shaped and are embedded around the nipple, it is not dirt either

OK have you ever seen an engorged tick? that sounds like what you are seeing. Are there little legs up near the skin where you pull them off?
You can get rid of them using a tick collar with Amitraz in it such as Tick Arrest or Preventic or you can use a product like Frontline any of those will remove and kill them.
You may need to spray your home to get rid of any that have dropped off and laid eggs.
You will have to have your dog checked for tick carried diseases if this is the problem.
You can read about and see some images of ticks here

No that is not it either as there are at least 20 small black clay like things around each nipple
Expert:  NancyH replied 11 years ago.
This could be a viral wart called canine viral papillomatosis.
They might be tumors.
You can read about this here

The third presentation is cutaneous inverted papillomas, which has more in common clinically with intracutaneous cornifying epitheliomas. In this disease of young, mature dogs, lesions most commonly develop on the ventral abdomen where they appear as raised papulonodules with a keratotic center. Infrequently, viral papillomas in dogs may progress to invasive squamous cell carcinomas.
and more is here
Multiple pigmented plaques: These occur on the ventrum and medial thighs of dogs usually from 2-4 years of age. This condition has previously been described as epidermal nevi. Papilloma virus has been identified, but there is also evidence to support heritability in Pugs and Miniature Schnauzers.
It is essential to collect a biopsy to confirm the diagnosis and also ensure that the immune system is competent. If there is no regression within 3 months, alternative therapies can be considered.
So could be viral warts or could be a tumor of some sort.
This site lists a lot of the skin problems and how to identify them
I think you need to have a vet look at and, if need be, biospy what you are seeing.
