are you dealing with? Sarcoptic (contagious) or Demodex (non-contagious)? Very different problems...
I agree with the others-a vet asap. It can spread and be harder to treat. Also, if you have other animals, they can get it. I'm not sure about humans, but that's always a concern. Best of luck.
The only way to really clear it up is by a prescription from your vet. Go see them.
Mange is not something you should fool around with. There are types that are very serious if they get a good foothold. It is not common for healthy, normal, indoor puppies to get mange, so get him/her to a vet asap. Seriously.
Its part of your responsibility as a pet owner.
You really should take her to see a vet. Putting household products on her can cause a problem.
Wish you the best.
