What's causing my puppy's painful armpit rash and what should I do?
Those spots on Bella could be several things including allergies, skin mites, flea bites, ringworm (which humans can get) or a bacterial infection. 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 her diet to something like Royal Canin or Nutro as they are aimed at skin health. The best option is to have Bella examined since the rash is bothering her. This will figure out the cause the fastest and bring her relief sooner. If you cannot get to the veterinarian's office, you can wash the lesions with soap once a day and rinse well (don't wash her whole body, just those spots). Protect the areas from licking or scratching with an elizabethan collar. If they don't start looking better within about a week or if they get worse, have her examined by his veterinarian who may prescribe medications. Best of luck and please feel free to post any additional questions.
