Rottweiler, 2 years old. Inside dog. No fleas or ticks. Healthy in every way except: She dog suffers from hot spots. She has been to the vet. Vet shaved the areas effected. Has taken second round of anti-biotics. Using hydrocortizone cream and anti-bacterial ointment on the spots. Washing spots with hibiclens. All of this per directions from my vet. The originals spots are healing up. Though we are getting new ones in different areas. How can I get this to stop? Every few days I find another new spot. She eats Innova EVO. It seems to be seasonal as she did the same thing last year, but this year seems worse.
