Hello. I am not sure exactly what you are seeing on your pug, but with allergies, the skin will sometimes become more pigmented with melanin. This is similar to when we tan from the sun, but in dogs, the skin is responding to chronic irritation. In the winter, the allergens go away, so the skin heals & becomes pinker. Thanks for using Petco Pet Education Center, formerly Petcoach.
