Dixie is a dog, right? She may just have dry skin, especially with the cold snap you guys got. What kind of shampoo did you use? I normally use baby shampoo. What breed is Dixie? I would call the vet to see if he has any recommendations. Our pug has VERY dry skin right now and scratching and chewing like crazy and it's because of her short hair, the cold, and the air in our house is so dry. We've started using an humidifier. If that's the problem, and you don't have an humidifier letting water simmer on your stove helps too with the moisture inside.
