Demodectic mange questions?

We adopted a dog from a rescue shelter only to discover that she had demodectic mange. She would itch and rub and roll and scratch until she was bleeding. The folds of her mouth were red and swollen and she had a spot that bled next to her eye where she would rub her face along the grass every second that she went outside. A skin scraping was done and the diagnosis of demodectic mange was made. She was treated with Ivermectin orally and an antibiotic. She never displayed hair loss as the rash like bumps and redness appear mainly on her belly and under her arms in the armpit areas. She has been on this medication for two weeks and she is not getting any better. She still itches and scratches and rubs like crazy which I have read is not a side affect of the mites. I have to take her for a follow up this week and I was wondering how long does this mange treatment take to start working? And also, I know that the mites are present in all dogs so wouldn’t a scraping show them present in every dog? Is it possible that she is suffering from an allergy on top of the mange which is causing the itching?
Erm, she has DEMODECTIC mange not SARCOPTIC mange…there is a difference.

Put the dog in t-shirts while she heals up. It controls the damage done by the scratching. Severe Demodex can take months to clear up, so don’t expect miracles.
The antibiotic is probably to cure a bacterial skin infection caused by the scratching.

Demodex mites are NOT visible unless they wake up. so no, you can’t do a skin scraping on just any dog and find mites. In healthy dogs they are dormant.

You need to get this girl on a really good diet and some immune booster vitamins.

The good news is oral Ivermectin is pretty cheap and works!
