    The fur beside and under your dog's mouth is exposed to dampness and food.

    If the only obstacle keeping your dog from looking as well-groomed as you do is the brown stain around his mouth, there are several ways to remove the unsightly discoloration. Check with your vet first to make sure the stain isn't caused by a yeast or bacteria infection.

    Items you will need

    • Washcloth
    • Milk of magnesia
    • Hydrogen peroxide
    • Corn starch
    • Ceramic bowl

    Step 1

    Wipe the dog's discolored beard with a damp washcloth daily, especially after your pup eats or drinks. This helps remove saliva, water impurities and food dye from the fur.

    Step 2

    Mix one part milk of magnesia and one part hydrogen peroxide with corn starch to create a paste. Start with a teaspoon of corn starch and stir the mixture to create a paste. If the mixture is too liquid, add more corn starch one teaspoon at a time until the mixture becomes more solid. Wipe the paste on the discolored fur without getting any in the dog's mouth. Leave it on for at least four hours, then remove with a damp washcloth. Repeat daily until the stain fades.

    Step 3

    Buy a food-safe ceramic bowl for your dog's water. Some metal bowls can rust, transferring the iron oxide to your dog's fur when he drinks.

    Step 4

    Change the food you give your dog to one that doesn't include dyes. The colors can leach into his fur, causing a dark discoloration.

    Step 5

    Filter the water you give your dog or use distilled water to remove elements that could be discoloring his fur.

    Tip

    • If you opt to cut the stained fur, get in the habit of wiping the area with a damp cloth every day to help the new fur stay clean.

    Warning

    • Beware of many commercial fur whiteners, which often contain bleach that can irritate your dog's skin.
