My sweet little chishi (chihuahua shitzu mix) has superficial pyoderma and is always itchy, even taking antibiotics and getting a medicated bath several times a week. He has one bad red spot now and I read that mixing apple cider vinegar with water and bathing him in it helps the itching. I also heard putting it on the red spot could soothe it. Anyone know if there is truth to this? He's such a good little baby. I hate to see him so itchy so much of the time. We are going to test him for allergies soon.
