My biggest suspicion is that these two ate something that really irritated their skin and set it up for infection. Certain house plants are a common culprit. There is not any contagious diseases that I can think of that would cause these sort of problems. The best things you can do is have them evaluated by a vet. They will be better able to find the cause of this and offer the best treatment. For now, it's good to keep the area clean with a medicated dog shampoo (you can usually get these in the pet store). Clean with cool water for five minutes, twice a day, wiping gently. With good cleaning, the infection usually clears within two weeks. I hope that helps and they get better soon.
