If your dog is chewing at its skin, licking excessively, rubbing against objects and on the ground, scooting (rubbing bottom along the ground), chewing/licking at feet, chronic ear irritation, watery eyes or, occasionally, sneezing, it may have an allergy.

As there are numerous causes for each of those symptoms and dogs cannot explain how they are feeling or tell you what they were sniffing at or eating when you were not watching them, a lot of detective work and elimination of other causes needs to be done before you can be sure the dog has an allergy.

If there are bare patches of skin and a dry brown discharge that looks like coffee grounds in the dog’s ears, then take it to the vet to have a skin scraping looked at under a microscope to make sure the dog does not have mite, also known as mange or scabies, before you begin treatments for eczema.

Mange is a debilitating, contagious condition that needs to be diagnosed and treated as early as possible.. Don't wait! Mange can cause extreme misery to the dog who may chew at their skin and leave raw sores on the skin. The word Mange refers to a collection of skin conditions in dogs and cats caused by tiny organisms called mites, which dig into and under the skin, feed and lay eggs. The eggs hatch in about ten days, feed on skin cells and blood and grow to maturity at which time the whole cycle repeats itself. These mites can live on dogs and cats and can cause intense itching, hair loss and rashes as well as a whole host of secondary infections caused by the digging, scratching and biting the animal does to relieve the itching and burning. In many cases, these mites can be transferred to human beings too thought they do not complete their life cycle on humans.

Mites are common in filthy environments, the best precaution is to burn suspect animal bedding and never pat or allow your animal to go near a cat or dog, with bald patches on their skin unless you are 100% certain they have been tested for and do not have mite-mange-scabies..

The Different Types of Mange

There are several different types of mange, the most common of which, and the ones we will deal with, are Demodectic Mange, Notoedric Mange, Sarcoptic Mange, Ear Mites, and Cheyletiella Mange.

Demodectic Mange sometimes called dog mange, also known as "demodicosis." lives inside the hair follicles, making it resistant to topical preparations. 

Notoedric MangeThis is the main cat mange. Never pat a cat with bare patches on the fur, as humans contract this mange through contact (touch),with the animal who has it. Dogs and other animals can also pick this mite up from contact with a cat with the condition.   

Sarcoptic MangeSarcoptic mange is very contagious and can be spread easily through contact with another dog or the environment where an infected dog has been. This type of mange thrives in filthy conditions. Sarcoptic mites can be transferred to any animal, including human beings, and people do pick up this condition by handling infected animals. Their bite can cause intense itching and burning in both dogs and humans. Although sarcoptic mange mites do not complete their life cycle on human beings, unfortunately the infection is passed back and forth between human and animal and will continue to itch and rash unless both pet and person are treated along with their environment 

Ear MitesEar mites are a relatively common parasite of both dogs and cats, sometimes visible to the naked eye as a tiny white speck in the ear canal of the animal. They are far more common in cats than in dogs. Their presence causes a dark, dryish discharge made up of dried blood, skin oil and ear wax that looks like used coffee grounds, along with itchy ears and a lot of head shaking. Ear mites are easily spread from animal to animal, but don't easily infect humans.

Cheyletiella MangeThis type of mange is also known as Cheyletiellosis or Walking Dandruff because when you look closely at the dog, you'll see white flakes of what looks like dandruff, except they move. This movement, is caused by the mites moving around under the skin flakes. Because Cheyletiella Mange mites lives on the skin surface and can be identified easily, it is the easiest mange to diadnose and treat.  Cheyletiella Mange occurs all over the body of the animal and is extremely contagious, with a high level of itch. People can be infected by handling dogs with Cheyletiellosis, and just like with Sarcoptic mange, this can set up a cycle where the mites are transferred back and forth, so it's very important to treat the environment and all infected animals at the same. Mite eggs also fall off the dog wherever he scratches, which means a large part of your surroundings can be contaminated.

Excema after reading about mange, you will be breathing a sigh of relief, if your dog, only has eczema as this may clear up within a few weeks once the irritant is eliminated, and the dog is brought into optimum health to improve its immune system.

Anti allergy diet is 50% wholegrain rice, 20% vegetables and 30% red meat or poultry.

Allergy proof the garden. Check, the garden, if your dog has skin irritations, as it can be a source of many poisonous and, allergy causing plants, the Wandering Jew, or Tradescantia zebrine is one of the worst ground cover skin irritation plants for humans and dogs.

Eliminate Fleas are one of the most common causes of eczema in dogs and these are easily, prevented these days.
