Hello & welcome...Yes, Kalola is right...An oatmeal base shampoo is best...Oatmeal relieves inflammation.
However, the itch is coming from something/somewhere....Make sure your using a good prescription flea medication (From your Vet)....
Also, if the food your feeding is grain based; any corn, wheat, soy, by-products, chemical preservatives or coloring agents, these are likely the culprits.......Karla
Natural Oatmeal Anti-Itch Shampoo by Bio-Groom seems to work the best for my TWO formerly itch itch itch, scratch scratch scratch dogs!! :) there are many good websites w/info and prices!!!
