Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on your description, it sounds as though Cherry Pie may have a skin infection. This infection may be from bacteria, fungus or both. I would recommend having her examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. If you are unable to get her to the vet I would recommend using the below recommended products which can be found online quite easily. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further. 1. Douxo PS Chlorhexidine combination shampoo and bathe twice weekly until resolved 2. Malacetic conditioning spray and apply to the affected areas twice daily until resolved 3. Essential 6 spot on by Dermoscent 4. Welactin omega 3 fish oil capsules for dogs.

    Hi, thanks for using PetCoach! From your description the white bumps sound like pustules which would indicate a bacterial skin infection. The black spots can be comedones but with out seeing her it would be hard to tell. It would be best to have your Vet examine Bella and provide a diagnosis and then treatment. Overall I love Omega 3 fish oils for skin. I like http://vrshealth.com/canine-products/omegadog/ If you want to bathe her in a medicated shampoo, try this one (https://secure.drsfostersmith.com/product/prod_display.cfm?pcatid=21564). Bathe 2-3 times per week, allowing the lather to sit on the affected areas for 10 mins before rinsing. I hope this helps and I wish Bella the best!

    Hi, and thanks for your question. 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!
