My dog's stomach spots are fading. Is this normal for a healthy dog?

Those spots could be normal skin changes for your dog, areas of chronic irritation such as from grass or laying on a rough surface, or rarely an auto immune disease. If they start increase in size, number, have any sort of redness or appear raw/ulcerated she get checked out by a veterinarian. For now I would recommend monitoring them and no special shampoo should be needed.

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.

This looks like hyperpigmentation. It typically occurs in lightly pigmented, sparsely haired regions as dogs get older. It can also be caused my inflammation so just make sure she is not spending too much time sunbathing and that there are no other signs like licking/scratching/lesions.

The pictures look like it could just be normal pigment change. As puppies mature their pigmentation can as well. If the skin is raised, thicker, crusty, or itchy then I would be concerned. If you have any concerns then I would encourage you to have him evaluated by your veterinarian. If there is a concern then a biopsy could easily be done at the time of his neuter. Best of luck and thank you for using Pet Coach.

Hyperpigmentation of the skin is common with age where there is no overlying hair. It can also be caused by skin irritation/infections but if there are no lesions or symptoms it is likely normal. No treatment needed in that case. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

This looks like normal pigmentation to me however it could also be post inflammatory hyperpigmentation from an infection. I wouldn’t be overly worried but I suggest you use these medicated wipes on the pigmented areas daily for 7-10 days. If no change then it’s either normal or you should have your vet check it.

Thank you for submitting your question regarding Daisy. She appears to have normal pigment variations on her abdomen for her breed. If one isolated area becomes very dark or she develops a raised mass, she will need to see her veterinarian. Otherwise, I cannot make out anything abnormal from your pictures. I hope this information helps!
