Dealing with MANGE

Demodex mites definitely cannot be transmitted to humans or to cats

- Dr Larry Kraitzick

Demodectic mange is caused by a cigar-shaped mite called Demodex Canis. Demodex mites are normal inhabitants of a dog’s skin that are passed to pups from their mothers in the first few days after birth. The mites then move deep into hair follicles where they reside, usually causing no skin disorders. Whilst a normal immune system will keep their numbers in check, in a dog with a weakened immune system, mites may multiply without restraint.

Predisposition to demodectic mange can be found in the following instances –

1. In dogs who inherit an abnormal immune system. These dogs often develop a serious condition known as juvenile Demodecosis

2. Elderly, sick, neglected, or stray dogs with weakened immune systems often develop demodex. An example of this is cancer, which can weaken a dog’s immune system

3. Poor nutrition

4. Drugs which suppress the immune system

5. Other skin conditions
