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.
