Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like it could be a skin infection. You can try to use a medicated shampoo containing chlorhexidine twice weekly for 2 weeks. If there is no improvement or in the meantime this appears to be getting worse, have her evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

    Darkening pigment can indicate a few things including normal pigmentation, minor allergies or irritation, or endocrine disease such as hypothyroidism. The best option is to have him examined by his veterinarian to look for other clues on the physical exam which may give more details.
    Starting an omega 3 fatty acid supplement for dogs can also help improve skin health.
    I hope this is helpful and please feel free to post any additional questions.

    This can be temporary change for unknown reasons or can be a sign of the start of an yeast infection from a low thyroid or allergy. It will be fine to monitor the area and if you notice lethargy or hair loss and weight gain or scratching then I would get her checked

    Hi, and thanks for your question.
    Even though a picture of it would really help to determine the underlying cause more precisely, this could be due to an allergy, although it could also be infection or mites.
    First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation.
    If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy.
    Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc).
    Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics).
    Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. If this answer was helpful please let us know, this will be used to improve our service!
