  Skin changes can be due to a number of reasons. Some breeds will have naturally patchy/darker skin in places like the belly, while aging may also cause minor changes. Health issues such as metabolic disease, or infections of the skin may also cause changes. If the changes is new or rapid, having a vet take a look in person is best.

  Any change in the pigment of the skin could indicate multiple possibilities so it is difficult to say. I will say that judging by the photos you provided, these appear to be harmless areas of hyperpigmentation that are likely related to middle to older age. The hair is thin in these areas so you also have the sun as a possible cause of the skin color change as the rays of the sun can penetrate through thinner hair much easier. I would monitor these areas for now and if more begin to show up or the become much larger or raised, then I would recommend having a veterinarian examine Flik so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

  Skin pigmentation changes can occur naturally as a dog ages if there are not other underlying health issues. That said, some skin conditions and metabolic diseases as well as allergies can lead to hyperpigmentation like this. In the case of metabolic issues, the pigmentation change is usually bilateral along the hind legs, while allergies can lead to skin changes along the belly, groin, and legs. If you've already scheduled a vet visit, that's an excellent thing. Your vet will likely recommend some testing such as bloodwork to check for metabolic issues, and a skin scraping to check for parasites/infections/irritation that could be causing the pigment changes. If allergies are suspected, additional treatment such as a trial of a daily medication or food change may also be beneficial. In the mean time, if you notice any itchy or irritated areas, keeping it clean and dry can help. If Indie is licking at any spots, an Elizabethan (cone) collar can also help reduce irritation.
