DEMODECTIC MANGE



The  demodex  mite  that causes this mange is a normal inhabitant 

of the skin in small numbers. In some animals the population 

explodes and you will note the hair-loss, a "moth  eaten" 

appearance, and sometimes secondary bacterial infections.  Usually 

the mange is localized but it can be generalized and even become 

chronic.



This mange is associated with a weak immune system, commonly seen 

in juveniles and often resolving with the maturity of the dog and 

it's immune system.



Mitaban dips (amitraz) is very helpful in the treatment of the 

mange.  Many dips may be required before the mange is pronounced 

"cured".  After the third or fourth dip the veterinarian should be 

checking lesions for signs of any live mites or mite eggs.



Typically the infestation should be self limiting and should 

resolve with time.  Occasionally animals may break out with the 

mange when over stressed, especially during estrus or heat cycles. 

Since the disease is modified by the immune system it will seem to 

run in certain familial lines and therefore I don't recommend 

breeding any Rottweiler that suffered a severe case of demodectic 

mange.  If only a mild case of localized mange was found, one 

would have to judge the animal's qualities before making the final 

judgement on breeding or not, but the demodectic mange is 

definitely a negative to a ever growing list on the decision 

sheet.
