Two of the most common causes for itching are allergies or insects- fleas or mites. Start by looking all over her body for fleas. Mites are harder to detect because they are microscopic. You could also try a diet change. Often a grain free diet can help.
When you can you afford it you might want to look at some of our products, Derma-IonX and Defendex shampoo to help heal the skin. Derma-IonX which is an oral homeopathic product stimulates the enzyme systems in the body which reduces itching and inflammation , promotes healing of the skin and helps with assimilation of nutritional components in diet and supplements. The supplements I use along with it include digestive enzymes, canine probiotics, Vitamin C, MSM, and fish oil (OMEGA 3,6,9). Together with Derma-IonX it produces a synergistic effect for a faster response. It can also be used topically if there are troublesome spots on the skin. I would also suggest that you give your dog only filtered water for drinking and bathing if your water contains chlorine or fluoride. Again for most skin issues I suggest a grain free diet for a while.
Defendex shampoo which was designed to fight against fleas and mites also washes away debris and soothes the skin. Using both products is a simple and effective way of helping resolve a difficult condition.
