I hadn't washed my dog for probably a good 3 months but four days ago I did. As usual I used the Aloveen oatmeal shampoo. Since then she has been scratching and chewing like mad and she hadn't been doing that before I washed her. No fleas. I have had a sneaky suspicion for the last year or so that the shampoo might make her itchy as it's been getting worse and because I hadn't washed her for so long I'm almost certain now it's the culprit. Could this be possible? If so, does anyone have any good
