My puppy has demoductic mange, the treatment is expensive and toxic to her health. other treatment options?

the form of mange is demoex. it causes her to itch like crazy. her ears have bumps and scabs. and she bites herself till she bleeds. if we don’t take her to the vets she is only going to get worse. but i haven’t read very many good things about it. are there any other options for treatments?
i have taken her to the vet and they say the dips will help but if it’s toxic to her health shouldn’t i be trying to find another option?
the treatment IS EXPENSIVE. and frontline and advantix are NOT an option. this form of mange is herreditary and is caused when the puppy has an immature immune system, not a stressed immune system. and we haven’t let it go for too long as some have suggested. we have taken her to numerous vets before one figured out what is wrong. she can’y die from this she is just beyond very uncomfortable. i just want to make sure there aren’t any other LEGIT solutions before we pay over 400 something for a treatment that is hazardess to her health.

Just do the dips, they are not the best but it will clearly help her in this case. Then, see if there is any preventative things you can do so this doesn’t happen again. Good luck and I hope your pup feels better!
