Dog Skin Itch Diagnosis

The first step toward diagnosis is to look at where you dog is itching and if you can tell the underlying cause of the itch such as red pimples or raw skin.

Is the skin itch localized (in one area)?
If the itch is only one location, then either a skin parasite such as scabies (mange) or food allergy may be the cause. Food is often the cause if you have made a recent adjustment in your dog's diet. If nothing changed in the diet, try a mange treatment such as Dermisil for Pet Mange.

Are there multiple skin irritations that see to be symetric? (patterns that mirror each other)
Causes are often internal such as hypothyroidism, hypoadrenocorticism or pemphigus foliaceus. Allergies may also be the cause.

Multiple skin pimples with no symetry
Common causes are parasites (fleas, mites)and bacteria. You can try a treatment such as the one indicated above that includes a miticide or anti-flea treatment.

Allergy related Dog Skin Itch

Symptoms of allergy include licking of the paws, face rubbing, belly licking and ear infections. Allergies usually start early in life and can last throughout the year or start with certain seasons.

Treatment for skin allergy includes a dietary supplement that contains fatty acids, baths with colloidal Oatmeal Shampoo , antihistamine, corticosteroid sprays or allergy shots.

Food Alelrgy and Dog Itch Skin

Symptoms of allergy are paw licking, face rubbing, ear infections. To treat try feeding your dog a simple food that your pet has never eaten before. If the allergy disappears than a food allergy is the cause. It is rare for a dog to have a food allergy. Consider a simple carbohydrate/protein combination such as Hills Duck/Rice food.

Contact Hypersensitivity

Symptoms happen suddenly and are a reaction to something that has changed in the dogs environment such as bedding or shampoo. Symptoms include itching on the abdomen, feet and chest. Itching can be helped with a colloidal Oatmeal Shampoo , antihistamine or corticosteroid sprays.

Skin Parasite Dog Skin Itch

Itching is caused by an insect that disturbs the skin such as a mite, flea or tick. Review our guide to each type of parasite to determine treatment. Mites (known as Mange or scabies) are best killed with a Miticide such as Dermisil for Scabies or Flea and Tick Shampoo.

Ear Infection

Primary symptom is scratching of the ears, ear wax and smell. Treatment includes ear drops and ointment.

Anal Gland Irritation

Symptoms are scratching of the anus and scratching by dragging the anus along a floor or carpet. Treatment is by draining clogged anus glands.

Bacterial Infections that cause Dog Skin Itch

Bacterial skin infection is the second most common type of skin condition after allergy (folliculitis). It occurs when there is infection at the base of the hair follicles. The condition is often misdiagnosed since it tends to be a secondary effect of other skin conditions such as skin allergy and flea allergy.

The disease looks different in each breed with further variation caused by the type of bacteria causing the infection. Papules (a small solid rounded bump rising from the skin that is usually less than 1 centimeter in diameter - less than 3/8 inch across) appear at the base of the hair follicles. Since they burst easily they are often crusted and move from area to area.

You can try Malaseb Medicated Pet Shampoo which is made to combat bacteria.

Seborrhea Dog Skin Itch

This condition is accompanied by dry flaky skin or skin that is greasy to the touch. Symptoms can include itch, thinning hair in patches, scabs, bumps and pimples.

Give your dog frequent baths starting with every other day for 10 days, then 2x a week, then 1x a week depending on the level of improvement you see. If your dog's skin is dry use a Medicated Dog Shampoo that contains sulfur or salicylic acid. If the skin is greasy use a shampoo what contains coal tar, benzoyl peroxide or selenium sulfide (degreaser for the skin).

Use warm water when bathing. Also consider an after bath spray that contains colloidal oatmeal, fatty acids, urea or glycerin.

You may want to consider an a natural skin supplement that contains fatty acids such as

Canine Endocrine Disease
