As it turns out, garlic isn’t only beneficial to human health – it’s also a wonderful remedy if your dog is suffering from mange. You can soak 6-10 cloves of garlic in water overnight, and the resultant water will be infused with many of the antimicrobial and antiparasitic compounds found in garlic. You can topically apply this mixture directly to the affected areas of the dog’s skin, and while the smell might be somewhat unpleasant, it will certainly get the job done. You can apply this mixture once a day to the affected areas and see significant results within a week.
