My dog's skin is changing colors

Hello I have a ten yr old dog named Dakota. Normally her skins is a very healthy pink color. Just this morning I was rubbing her belly when I noticed that her skin was turning black. At first I thought maybe her skin was dirty since she was outside yesterday, but after washing her down I saw that it wasn't dirt and the discoloration wasn't coming off. I immediately checked to see if the discoloration was limited to her belly but it turns out the discoloration is spreading all over. I have had many dogs in my life and have never had this happen. Does anyone have any idea what could be going on?

Will Draper, DVM responded:
Chari- this is called "hyperpigmentation". In older dogs, this can be a sign of a low thyroid condition (hypothyroidism). It is something that can be ruled out with a common blood test, which checks your dog's thyroid hormone serum levels, as well as the thyroid stimulating hormone levels (the latter are secreted from another gland, which it turn directs the thyroid gland to do its job). If it is the case, it can be remedied with thyroid hormone supplementation- which is generally pretty inexpensive and easy to administer (small pill).

If the thyroid levels are normal, your vet may want to consider a skin biopsy to help determine why the color changes are taking place. Either way, a vet visit is in order. Best of luck...keep us posted!
