I have a 5 yr old Labrador and is always scratching and chewing the base of her tail, at first i thought fleas, but i have eleminated that. i also thought dry skin, but i have been feeding here a omega 3's and 6's rich diet and giving here fish oil vitamins every day. along with bathing here in a hair and mane shampoo + conditioning here in a 5 natural oil conditioner. after the bathings she seems to have some relief but anything short of daily bathings wont give here long term relief, and anyone that's owned a Lab knows bathing them is a pain. ANY IDEAS?
