Hi Lorri,
When we first got Millie, she was on Eukanuba - she was very itchy and had flaky skin too. We changed to Burns, which stopped the problem completely, but she lost a lot of weight as she didn't really like it, so we went onto Nutro - Lamb and rice, which is specially formulated for the conditioning of coats and skin (at least thats what it says on the bag!
)
Since the change she has eaten much more, and is now a good weight, and hasn't been half as itchy, although recently she has been a bit scurvy and a little static-y, but we've put it down to the atmosphere being so dry, as she's gotten better with the weather turning a bit wetter
Brushing with a soft bristled brush, or 'hound glove' is good as well as it stimulates the natural coat oils to be produced, which should improve the skin and coat condition.
Or, if you're feeling particularly extravagent, a pureed avocado mixed with olive oil makes an excellent natrual conditioner for dry skin and fur/hair (its good for people too!) just massage into wet skin/hair, leave for 5 minutes or so then rinse out well
HTH
