This appears to be normal skin pigmentation. There are some diseases that can cause skin pigmentation like that and since your dog is very young it is unlikely that he is suffering from those: Skin cancer (can be ruled out with a skin biopsy), hypothyroidism (can be ruled out with a blood test), and Acanthosis nigritans (Hyperpigmentation). But as I said, this looks like normal pigmentation. THere is no way to diagnose this from a photo, so a veterinary exam will be able to diagnose any problem, if present.
