Home Remedies for Dogs with Mange

i have found giving dog rubdown with 3% peroxide cures skin diseases very quickly, he will scratch and itch for awhile but it will clean up his skin in less then 3 days, i have street puppy in philippines and used peroxide and could not beleive how fast his fur grew back i used small cotton and swabbed the peroxide on the worst spots first then next day put it in my hand and rubbed it all over
