Demodex Mange in Dogs and Cats, Diagnosis, Localized and Generalized Types of Demodex Mange
Demodex are really tiny mites that are shaped like a cigar and they have eight legs. These mites typically inhabit the skin of dogs. The infestation of demodex mites among dogs is called demodex mange or demodectic mange. Both young and old dogs are affected, although demodex infestation gets more severe when older dogs are involved.
When the number of demodex mites in the skin of the dogs is small, it does not cause any problem. However, their number goes significantly higher when the immune system is not strong enough to control and fight them. This means that young puppies and older dogs with compromised immunity are the usual victims of demodex mange. In addition, there are also some bloodlines that show high occurrence of demodex mange, reflecting the possibility that there may be immune susceptibility that can be passed from generation to generation.
There are two types of demodex mange: localized and generalized. Localized demodex mange typically affects dogs below the age of one. It should be noted that this kind of skin disorder commonly heal by itself in a span of six up to eight weeks. However, when the patches present already exceed five, this may mean that the case is progressing and becoming generalized demodex mange. There is up to fifty percent likelihood that the puppy will be able to recover without the need for treatment. However, when it occurs to dogs that are older than the age of one, it is not expected that the skin disease will improve by itself. With proper medical treatment, the dog is highly likely to recover. As long as the owner is dedicated in giving time and spending money for the treatment, the dog is very likely to recover from the skin disease.
The diagnosis of demodex mange can be made by scraping the skin in a gentle manner, with the use of a sharp instrument. The sample will then be examined using a microscope. It will then expose the kind of demodex mite that has affected the dog.
Once demodex mange has already been treated with proper medication, majority of dogs do not get affected by another instance of infestation. This is because their immune system already knows how to defend itself against the mites. On the other hand, it should be noted, that there are particular dogs that are not capable of creating immune factors that will battle against the mites. Due to their genetic attributes, they may suffer another case of demodex infestation. This aspect is hereditary, putting dogs at a predisposed position to have an unresponsive and severe kind of demodex infestation.
