Burnt Motor Oil<br>My dog Duke had an affliction where he kept scratching over and over. The vet told us that it was mange and to treat it with used motor oil. We splattered him with used motor oil, and he sat outside for a week. This was an indoor dog so it was truly sad for him, howling at night. Turns out it wasn't mange but an allergy to grass, common in mutts.
Dog allergies are easily treated with medication
