First of all changing to a food with less overall ingredients is essential. Foods like Natural Balance, Wellness, Chicken Soup for the Pet Lover's Soul. Try alternating them from time to time in insure greater nutrition.

Also try offering some organic live bacterial culture yogurt daily. Two tbsp daily. Also purchase some whole organic flax seed and start with 1 tbsp daily for one week then increase up to 2 tbsp. The omega fatty acids along with the lignans help to support the immune system, joints, bones, skin, heart. Alternate from time to time with a good quality cod liver oil. I usually do three weeks in rotation.

500 mg natural source vitamin c daily broken down into 2 250 mg servings. Helps to support the urinary tract and assists with the absorption of other nutrients. The best way to deal with skin conditions is from the inside out.

Also look to the drinking water, many animals with skin conditions have a low tolerance to the inorganic minerals in tap and bottled water. Offer distilled water instead. Also simple flea allergy cannot be ruled out. With some unfortunate animals, a single flea bite can create a systemic disturbance and severe allergic reaction. If you think it is possible your pet could be exposed to even a single flea bite in this situation it is imperative that monthly flea control be instituted with a control such as frontline.

There is nothing more distressful to a pet owner than watching our beloved pet suffer with itching burning skin. Frequently we head to the vet for that injection of steroids which unfortunately undermine our pets immune system further and create a revolving door to chronic illness.

Start with the supplements and one new simple ingredients food like Wellness. No other foods should be offered. That includes raw hide bones that are chemically treated with toxic chemicals to remove the hair etc. No box treats. Just basic simple food. Watch out for the common allergens in food. Corn, Wheat, brewers yeast. white potatoes (sweet potatoes are fine)

I recently consulted with a woman who's pet has suffered for years with itchy skin conditions. In just weeks she has noticed marked improvement. Oh, and also, keeping the skin free of moisture that contains bacteria is essential in the first few weeks.

A good oatmeal shampoo from a health food store or general nutrition outlet would be helpful. It does not need to specifically to be a pet shampoo. There is one ingredient you want to see listed however, colloidal oatmeal. There is one ingredient you do not want to see. Sodium Laurel Sulfate, added as a lathering agent in most commercial soaps and toothpaste.

And finally, purchase some essential oil of Lavender and a spritzer bottle. Add approximately 300 ml of warm water and 5 drops (drops) to the bottle and shake well. Mist the skin several times daily. The oil is antibacterial, and will greatly soothe the itching in the interim. (never ever however, use any essential oil in any dilution on a cat) they are unable to metabolize and a single drop can be fatal. The more dilute hydro sols can be used for felines.

There is a company in Canada that has essential oils in much larger volume for far less expense that what you can purchase retail. Even with shipping you will get 3-4 times the amount for less than a single little bottle at the store.
