Organic Apple Cider Vinegar
Apple cider vinegar for dogs may help prevent itchy skin while soothing skin irritation and rashes. Since it's acidic, it may also prevent yeast infections on the skin and ears. In addition, the acidic compounds in apple cider vinegar can eliminate dandruff and treat some mild skin conditions like hot spots.
Use no more than one tablespoon per 50 pounds of bodyweight and limit your use to twice a week. If your dog doesn't like the strong flavor, try reducing the amount to 1 teaspoon per 50 pounds of bodyweight, stirring some into your dog's fresh meals or water.
