There are two common types of mange Demodex and Sarcoptic.

Mostly all dogs have some Demodex mange mites on them, its usually when something weakens and compromises there immune system is when the Demodex goes out of control causing rise to certain noticeable symptoms. Even some people have demodex mange mites on them but they usually cause no symptoms in humans. Demodex mange is not inherited but can be passed on from mother to pups or from any other dog contact. Whats inherited in the pups is the weak immunity against demodex mange mites that have been genetically passed down from the parents to certain individual off springs. Usually pups going through immunity changes are more susceptable to demodex as well as senior dogs who have weaker immune systems.

Sarcoptic on the other hand is very contagious meaning, regardless of ones immunity level , it will cause considerable amount of damage to your dog if not treated. Sarcoptic mange can also affect HUMANS and be a hassel to treat.

There are many treatments to mange, but its a slow and on going steady process that could take even months to treat. Common treatments is Dursban, Amitraz, Mitaban dips, Ivomec, Nustock, Permethrin and certain shampoos and antibiotics for secondary infections.
