Hello, Prevention is in maintenance and treating for any underlying disease which is most likely an underlying allergy. Allergies in dogs are as variable as in people. Dogs can be allergic to food, dust, pollen, molds etc. any time of year or all year long. The allergy can be very mild or severe but in either case they open the door to secondary infections like yeast or bacteria. So the solution is to talk to your vet about potential diet changes, use of antihistamines and daily cleaning or topical treatments of any affected areas to keep the allergies in check and prevent reinfection.
