My boy had skin scrapes done while he was awake. He squirmed a little while being held, that was all. I would NEVER put a flat-face under just for a skin scrape. There is a tiny bit of blood but, the scrape takes seconds to do and is no where near cruel! Demodex Scrapes often show nothing at all, it's just a tiny part of the diagnosis - the vet should look at the other symptoms too. He was 9 months at the time, had generalized patches of hair loss on face, flanks, shoulders and neck, has had no other flare ups and so was classed as juvenile demodectic mange.
We brought the Aludex home - for our frenchie, we filled a jug with 500 ml of water to 5ml of Aludex, dipped his feet first, with cotton wool balls we swabbed the parts of his face showing hair loss and redness, then with a sponge, saturated his body. He had to wear a cone until he was dry - there was no rinsing - we had to do it weekly.( luckily Eve was wearing a cone as well, at the time having had surgery, so she couldn't lick him either!!!) It IS horribly strong stuff - you must wear gloves, wash any offf your skin immediately and not allow the dog to lick it. We did it 8 times in all. Luckily we only needed the one bottle as it was £60. We all think his demodex flared up because our girl was in and out of the vet, often staying whole days and he would become very stressed without her, wouldn't eat, play etc. I've pointed out to hubby that we need another one to save it happening again!!! ;-)
We also were given a spray to use when the itching got too bad - demodex itself doesn't cause itching but any secondary infection does - he had a sore place at the back of his neck, a lump that he continually scratched at.
I will say that I've since heard that no bully breeds should be given Aludex, but it was fine for our boy - he had no side affects or worse! from it! What breed have you got?
Our vet said, that if the aludex didn't work, we would have to use ivermectin dips off licence - the vet would have done the dip.
By the way, our dog was already having a monthly dose of Advocate and it didn't stop the demodex from flaring up!
Ask to see another vet at the practice, they may have different views on the scrape. I hope your girl gets sorted soon, they look like little moth eaten jumpers while they're patchy! :-D
