Hello, my name is Dr. Shines and I am happy to help. Looking at the photo I see 4-5 distinct black dots that look to be the pore opening of his teats (they match on both sides so that's how you know). I also see darker skin discoloration around his prepuce. Sometimes this darker discoloration is natural and happens as they age. Sometimes it can indicate a thyroid disorder. Sometimes it indicates allergies. If Yogi doesn't seems bothered by it, it's not itching and he's not excessively licking it, it's probably normal. If it's looking red at all or he's licking at it, then I start to suspect one of the other two causes. Sometimes improving over all skin health can help. For that I recommend a fatty acid like Welactin and a potentially a diet change to Royal Canin or Nutro (both great diets for skin). It will take about 6 weeks to be effective. Washing him in an oatmeal type doggie shampoo and conditioner can also help. If that's not helping, make an appointment for an examine. Sometimes they need stronger medication or they need a blood test for the thyroid. I hope this helps and please feel free to reach out with any additional questions.
