What are these black dots or discoloration around my dog's nipples?

Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like a focal infection. You can try to use a medicated shampoo containing chlorhexidine twice weekly for 2 weeks. If there is no improvement or in the meantime this appears to be getting worse, have her evaluated by a veterinarian for further assessment and treatment. Good luck and have a good day!

Those look like nipples. You can check to see if there is a line of these on both sides of his ventrum. They usually start from the groin area and go up to the chest. There may be 10 nipples (5 on each side). Some dogs have only 6. Love the name Milo…best wishes!

These look like they are probably blackheads/comedones. https://www.petinsuranceu.com/comedone-syndrome-in-dogs/ Most of the time this can be treated at home with a benzoyl peroxide shampoo designed for dogs. Here's a great one: https://www.amazon.com/DermaPet-Benzoyl-Peroxide-Shampoo-DermaBenSS/dp/B00JBCGQNS/ref=sm_n_ma_dka_US_pr_ran_0_0?adId=B00JBCGQNS&creativeASIN=B00JBCGQNS&linkId=e62eca48c814102998ed6a0ec5b5b13f&tag=consumadvoca-20&linkCode=w43&ref-refURL=https%3A%2F%2Fwww.petinsuranceu.com%2Fcomedone-syndrome-in-dogs%2F&slotNum=0&imprToken=786O2r4KrtUEdPZP8q0xkQ&adType=smart&adMode=manual&adFormat=grid&impressionTimestamp=1555519537984 If she is licking at them a lot, or seems bothered in these areas, have her examined by your vet, as sometimes secondary bacterial infections can develop. Thanks for asking PetCoach!

That looks uncomfortable. It's impossible to know at this stage if the nipple is infected or if the skin on/around the nipple is inflamed and this is causing the enlarged size. The block dots could be flea dirt, blocked pores or debris Patrick has laid in. Your best option is to have Patrick examined by the veterinarian and to get medications to help the itchiness. These lesions could be several things including fleas, allergies, skin mites, bacterial infection, ringworm (which humans can get) or endocrine disease. If you can't get him in to the veterinarian, there are a couple things you can do at home and they can help but they may not address the underlying cause. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash the lesions once a day (not his whole body, just the lesions). Also protect the area from trauma by having your pup wear an elizabethan collar at all times. If the lesions do not start improving within a week or if they are getting worse, have him examined by the veterinarian. I hope this helps and please feel free to post any additional questions.

These are comedones (black heads) and usually due to an underlying metabolic disease or a skin infection possibly caused by mites. Your veterinarian will be able to perform blood work as well as a skin scrape and cytology to check for any of these diseases.

They look like clogged skin pores (like blackheads in humans). You can try a dog shampoo with benzoyl peroxide to flush the pores, but it doesn't often cause issues. Don't continue to try to pull the black material out.

It sounds like your dog has a skin infection. Usually infections are characterized by small red pustules full of pus. But sometimes they can look like whiteheads or blackheads, also known as comedones. Your dog will likely need a medicated shampoo to help flush out his hair follicles that have become clogged and often times need antibiotics to help the infection cleared up. There is a chance as well that this may not be an infection but maybe small cysts that are present. If this is the case usually no treatment is needed. A picture for reference would help us determine if an infection is present or if it is just a cyst. I hope this helps. Thanks For using Petco Pet Education Center, formerly Petcoach. Best of luck.
