Or you can go to either Tractor Supply or Atwoods and buy this dip, which will cost less than $20 bucks. And will seemingly last forever.
This will rid most dogs of "red mange" or demodectic mange.
You can mix a garden push cart full, 5 gal bucket or trough and completely submerge the dog in it, whichever is easiest for you.
Do this daily mix according to packing directions. This will also make them shine like a new penny...and if you have any cuts or scrapes. It will dry and heal them up with the quickness!
As well as protect against flea and ticks should you have that problem as well.
