Does My Dog Have Mange?

Ask your Veterinarian why they declined to do a skin test? a simple procedure thay would have learnt at University.

I am a veterinarian and agree w/ yorkiepoo on many points. However, be cautious w/ waiting to treat generalized demodex. Secondary skin infections are common and can be very uncomfortable when they occur. I personally do not recommend breeding any pet that has had demodex b/c it is congenital. Many pets will clear on their own, but once it becomes generalized (two spots or more), I tend to recommend treatment. Promeris is also approved for demodex now and is 96% effective (more effective than anything else in studies). Ask your vet for more info and treatment options. Most popular is Ivermectin, but Promeris is much easier/less expensive/more effective/FDA approved for demodex. Good luck!

Yes you do need a second opinion if this does not clear on it's own. A skin scraping under the microscope is the only way to diagnose this type of mange.

Demodectic mange is also contagious, in that most dogs acquire the infection from their mother. The mite usually lives in relative harmony with the dog and it is assumed that most dogs have Demodex canis mites on their body. If the dog's immune system is competent the mites are suppressed and never achieve large enough numbers to cause damage. Sometimes, local areas of the skin are affected by hair loss (alopecia) and secondary bacterial infections are common.

When there are a number of spots, or the spots have spread over large areas of the body and when these spots do not clear up without treatment in four to eight weeks, the dog is said to have generalized demodectic mange. Localized demodectic mange is thought to occur due to transient stress or a decrease in local immune function at the affected sites. Generalized demodectic mange is thought to be due to a specific deficiency in T-cells that suppress these mites. This is thought to be a hereditary condition but if the exact mechanism by which inheritance occurs is known, I am not aware of it.

The best way to tell if the condition is severe enough to warrant the assumption that it can be passed on to future generations is to wait and see if it clears up on its own. For this reason, we try not to treat demodectic mange until it is evident that it will not get better on its own. At least 80% of dogs will outgrow this condition. The dogs that do not get better and require treatment can usually be cured, or at least managed and controlled, in about 80% of cases -- so the risk of this being a life long infection is not so high that you should worry excessively about it at this time.

I am not aware of any evidence that there are benefits to immune system therapy, probably because this does appear to be a pretty specific defect in the immune system. The odds are very good that this will all turn out OK. If you intend to breed Indy, it is much better not to treat, in order to be sure of whether the problem is generalized demodectic mange. If you do not intend to breed Indy, it probably doesn't matter if you treat at the localized stage but amitraz dip, the only approved medication for demodecosis, has serious side effects, including causing death in up to 3% of patients treated with it. Considering that waiting to see what happens is successful therapy in 80% of dogs, taking this risk prematurely does not seem justified, to me.

I know that many people disagree, but I think that the major brand name dog foods are all reasonable choices for most dogs. I am not aware of any major benefits or problems with treatment or occurrence of demodecosis that have been linked to diet.

I think that my dog has mange. She is loosing bits of hair everywhere. What can I do?
