It looks like Izzy has something called comodones - basically tiny black heads or pimples. A shampoo with benzoyl peroxide will help flush out the hair follicles and can remove these black specs.

If Izzy is otherwise totally normal (eating well, good energy, not hair loss or weight changes), you can buy an over the counter shampoo with benzoyl peroxide and bathe her twice a week for 2 weeks. During her bathes lather her up and then let her sit for 10 minutes (or as close as you can get, not all dogs tolerate this!) and then rinse.

If Izzy starts getting itchy or having any other problems, I would recommend a trip to the veterinarian clinic for further evaluation.

Good luck! Let me know if this was helpful information or request a consultation if you'd like to know more.

    Hi there

    It looks like Izzy could either have a flea infection or a bacterial infection. Fleas may not be visualized but can leave black specks called flea dirt. It may also be bacterial which can clog the pores and cause what you’re seeing.

    I’d recommend treating her for fleas with a topical product but before that giving her a good bath with an aloe and oatmeal shampoo. I would also recommend a vet exam for skin testing to be able to narrow down exactly what’s causing it and getting treatment to fix the issue.

    Best wishes to you and Izzy! Thanks for using Pet Coach.
