She had been on this food since we brought her home. If she has allergies, would she have not reacted to it before now? The groomer noticed that she has flakey skin and thought that it might be the dry air and suggested the shampoo. It did seem to calm her itches some and it made her hair very soft and silky. But after a week, she is starting to scratch a lot, again....even during the night when she is sleeping. Not sure what to do or think. Maybe it is the food. I hate to try something else as I just bought a new bag of RC. I will if it helps. I just don't know what to try without know the cause of the itch! Anyone have ideas, please let me know. Thank you in advance!
