My little Yorkie, Henry Lewis, has itchy skin problems. My Vet gave me Keratolux Shampoo to use. I have just started to use it; however someone told me to use Douxo Chloehexidine or the Douxo Calm Shampoo. Has anyone used either of these products. Or do you have any other suggestions. I have spent a ton of money on products to no avail. My Vet says skin issues are allergy related. No yeast, fungal, or bacterial issues according to skin scraping. I am new to YorkieTalk so please bare with me.
