Pustules and a foul odor are a sign of infection, which could have been caused by fleas, allergies, mange, ringworm, heat rash, or excessive skin folds. Depending on the cause of the infection and the bacteria produced, it is possibly contagious. I recommend that Flippy see a vet as soon as possible. While you are waiting to go to the vet, you can use a calming, antibacterial pet shampoo like Dechra MalAcetic Ultra Shampoo, and make sure to dry gently but thoroughly in any skin folds.
