localized demodectic mange in puppies

[Aleron]

It does take awhile for the hair to grow back but treatment doesn't really help that. The vast majority of cases clear up with no treatment, yet many vets strongly push treatment right away. Treatment which tends to be rather toxic unfortunately. If you want to know that it is for sure Demodex, you will need a skin scraping. However, be aware that your vet may urge you to treat and know ahead of time if you want to or not.

"Two clinical forms (localized and generalized) of the disease exist. Localized demodicosis occurs in dogs <2 yr old, and most of these cases, especially the nummular forms, are thought to resolve spontaneously. Lesions consist of areas of focal alopecia, erythema and/or hyperpigmentation, and comedones. Pruritus is usually absent or weak. A percentage of these cases, especially the diffuse localized forms, progress to the generalized form. ... Nummular localized demodicosis can be left untreated. The prognosis for this form is usually good, and spontaneous recovery is frequent." http://www.merckvetmanual.com/mvm/index.jsp?cfile=htm/bc/72005.htm"]

"Localized demodicosis occurs as isolated scaly bald patches, usually on the dog's face, creating a polka-dot appearance. Localized demodicosis is considered a common puppyhood ailment and approximately 90% of cases resolve with no treatment of any kind." http://www.marvistavet.com/html/demodectic_mange.html


"Localized mange usually heals spontaneously in six to eight weeks, but may wax and wane for several months. " http://pets.webmd.com/dogs/demodectic-mange-dogs
