I have a VERY itchy dog and read if we use baby oatmeal for an oatmeal bath it will give her relief. Just wondering - if we bathe her in that, do we rinse her off with plain water?
If your dog has grain allergies causing the itching DO NOT use oatmeal or oatmeal shampoo!
If your dog's skin is red and irritated a good antibacterial antifungal shampoo with miconazole and chlorhexidine in it would help tremendously!
I used Malaseb Shampoo on my allergic Cairn Terriers ...worked great!
