Why does my dog have dandruff while in heat? How do I treat it?

Updated On September 23rd, 2025

Pet's info: Dog | Rottweiler | Female | unspayed | 3 years and 3 months old | 58 lbs

My 3 yr old pittweiller is in heat and I have noticed that she has dandruff all over her... like snow! How do I treat this? (I bathe her regularly w/ oatmeal bath already) And could it be her hormones causing this? Or the winter weather? We use electric heat but have since November and this dandruff just appeared on her this past week.

Although it could be hormone related, the dry weather, a diet without enough fatty acids, oil gland problems or skin mites could also be to blame. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash in her oatmeal bath once a week (as long as that does not appear to over dry her skin). Many flea products can kill mites and you may want to have her examined to check for mites which is easy. I hope this helps and please feel free to post any additional questions.
