Without images or a physical exam, it can be difficult to determine definitively what is on your pup's skin. That said, many puppies have patches of [darker skin](https://www.petcoach.co/dog/condition/pigment-changes-of-the-skin-and-coat/) on their bellies. If these areas are flat, smooth to the touch and not bothering him, then it is probably just his skin coloration. If the areas are itchy or raised, then it would be a good idea to have them checked out by a vet since this may indicate a [skin infection](https://www.petcoach.co/dog/condition/staphylococcal-pyoderma-1/) or some other problem.

    Without seeing the black spots in person, I can't say the ones on Mika's belly are normal or not. They could be caused by [hyperpigmentation](https://www.petcoach.co/article/causes-of-pigment-color-changes-in-the-skin-coat-of-cats). The black spots are in most cases harmless and not a cause for concern especially if they are not accompanied by signs of irritation and only affect the fur with no significant changes to the underlying skin. If the spots are itchy to Mika, he has hair loss around the area, it's crusty, or he develops [fluid filled bumps](https://www.petcoach.co/dog/condition/skin-ulcers-and-draining-lesions/), then it is something more serious, such as [bacterial infection](https://www.petcoach.co/dog/condition/staphylococcal-pyoderma-1/) or fungal infection. I'd recommend taking him into your vet for them to examine the black spots, and to determine definitively what is causing them.

    Thanks for using Petco Pet Education Center, formerly Petcoach! It is hard to know for sure based on these pictures though this is likely a normal pigmentation change. If it is not associated with itchiness or discomfort, there is no need to be too concerned about this. If you ever notice any discomfort or itchiness, have her evaluated by your veterinarian for further assessment and treatment. Good luck and have a great day!

    It may be normal for her however, that black pigment could also be the start of a fungal or bacterial infection of the skin. The only reason I think it may be normal is because it appears to be bilaterally symmetrical (the same on both sides). I suggest you monitor it closely and if there are any significant changes then take her to the vet for evaluation. Hope this helps. Best wishes.

    The large spots appear to be normal skin pigmentation and are likely no cause for concern. The smaller spots may be simple dirt or grime. You can use a pet wipe or a plain, unscented baby wipe to clean her as needed.
