Dog hair loss does not always have a directly observable cause. In some cases there may be underlying diseases, but as in the case of humans it could be resulting from a simple change in the dog's body chemistry, resulting from hormone changes. Or dog hair loss can be attributed to the food that the dog eats.

One clear example of a chemical response may be dog hair loss that is observable on the tail of the dog. There is in fact a gland at the base of the tail that often results in hair loss for that particular animal. There are also certain anal irritations that a dog may have that may result in a dog's loss of hair on the tail as well.

Human Perspective

It is quite true that dog hair loss is more often a concern to the dog's owner than the pet itself. However, this consideration is very important as there are several steps that can be taken to reduce the risk of your dog encountering hair loss. First if you are a pet owner with a long haired or thick haired dog you need to carefully consider your climate. In the heat of the summer this form of hair can become clotted, dirty and be an ideal home for fleas and parasites. Therefore, if your standard flea medicines are not working you might need to consider cutting your dogs hair short as a prophylactic treatment to prevent your dog from losing hair.

Many humans also think that consistent bathing also helps. However, a dog's skin and coat are much better protected than a human's skin and hair with oils and other natural resisting agents. Over washing your dog can actually cause a dog's hair loss. Use of certain flea treating shampoos is very helpful especially in longer haired dogs, as they do prevent fleas clinging to the hair. Actually, if a dog smells awful, washing them is perhaps better left to their own tongues.

Dermatological Treatment

One option for handling ordinary dog hair loss, is a visit to the veterinary dermatologist. In many cases the dog may be allergic to a simple fleabite. There is a technique known as hypo sensitization that involves injecting small amounts of the allergen into the body of the dog in the hope of creating some resistance to it. This does not always work, but is one means of preventing a dog's hair loss.
