What is demodectic mange?

Demodectic mange, also known as canine demodicosis, usually occurs in localized form .That is to say it affects only small parts of the skin, however, sometimes it can occur in a generalized way and in these cases it becomes a much more dangerous and complicated disease to treat.

Elacaro Demodex canis is the cause of this scabies.It lives in the hair follicles and Sebaceous glands of all dogs, healthy and sick.Normally, the dog's immune system is responsible for keeping the population of sosacaros under control.However, when that system fails and defenses go down, the population of D.canis soars and causes the disease.

Dogs at risk of suffering from scabies are those that have some type of immunosuppression .This may occur due to some disease, seasonally (for example during the heat season in females), due to hormonal changes during growth or, due to stress or genetic causes.It is finally considered that hereditary mange is sometimes called demodectic mange, but it is a misnomer because even if the immune deficit has hereditary bases, the cause of the disease is almost clear.
