That's a surprising statement- if it's mange she certainly won't outgrow it- it needs to be treated.The breeder says it's probably mange and that she'll grow out of it.[/b]
Demodectic MangeDemodectic Mange
Demodectic mange is caused by Demodex canis, a tiny mite that cannot be seen without the aid of a microscope. This mange strikes puppies from three to 12 months old.
The demodex mite is commonly present in the pores of puppy skin and usually does not cause symptoms, and it not at all certain what causes them to activate. The mites can produce a substance that lowers the dog's resistance to them and make use of an opportunity to multiply.
It's also possible that some lines of purebred dogs carry lowered resistance to the mites, and that stress can trigger an active infestation. In any case, demodectic mange symptoms include thinning of the hair around the eyes and mouth and on the front legs that evolves into patches of hair loss approximately one inch in diameter. This mange may correct itself within three months or may require treatment.
However, demodectic mange can also begin as a localized infestation and develop into a generalized case with multiple hair-loss sites on the dog's head, legs, and body. This is a far more serious condition and requires veterinary attention. The dog's skin is sore, crusty, and oozing; the hair follicles are clogged with mites and debris. Treatment is extended and requires bathing in medicated shampoo and application of an insecticide to kill the mites.[/b]
CAN THE PUP BE BRED LATER?
Sometimes the puppy with localized demodicosis was obtained for breeding purposes. The current recommendation is not to treat these puppies so that we can determine if the condition will stay localized and resolve or if it will generalize. If it stays localized and eventually resolves without treatment, the animal is still a candidate for breeding. If the condition generalizes to cover the entire body, the animal should be sterilized. If the condition receives treatment and resolves, we will never know how the disease would have gone in its natural state and will not know whether the pup is carrying the genetic predisposition for demodectic mange. In this case, it is best to be conservative and not take the chance of passing on genetic predisposition for this disease.
Localized demodicosis is almost exclusively a "puppyhood" disease. When a puppy develops localized demodicosis the chance of the condition resolving is 90% unless there is a family history of demodicosis in related dogs. In this case, chance of spontaneous resolution drops to 50%.
Occasionally an adult dog develops localized demodicosis. We currently do not have good understanding of the prognosis or significance of this condition in an adult dog.[/b]
