Jude, I had the same problem with my Great Dane. My vet said to make sure he doesn’t come in contact with plastic; no plastic food/water bowls, etc. Also make sure that food and treats do not contain wheat, corn, soy and do not give treats high in gluten such as Greenies or Dentastix. If ears itch try using Novalsan Otic on a cotton ball to clean out the ear canal. I saturate the cotton ball with the Novalsan otic and press the cotton ball into the ear to squeeze out the liquid and then rub the base of the ears for a minute to help cleanse. Then stand back because she will shake the cotton balls out of her ears.
For skin itching you might try Equyss Micro-Tec Equine Spray from http://www.KVSupply.com.
It’s all natural and non-toxic. I spray it on him and brush it in all over
