Dogue de Bordeaux dogs can be especially prone to itchy skin caused by environmental allergens, seasonal changes, or food sensitivities. Persistent scratching can lead to irritated skin, hot spots, and discomfort if left unchecked. While it’s important to work with your veterinarian to identify the underlying cause and rule out parasites or skin infections, certain natural ingredients may help support healthy skin, reduce inflammation, and promote a healthier immune response. Below are eight natural remedies that many pet owners use to help soothe itchy skin and keep their dogs more comfortable.

Best Natural Allergy Remedies for Dogue De Bordeaux
1. Give Your Dogue De Bordeaux a High Quality Fish Oil Daily
2. Try Adding Quercetin To Your Dogue De Bordeaux’s Diet
Quercetin is also known as “Nature’s Benadryl.” This ingredient has become very popular in recent years for dogs as it helps suppress inflammation in the body. It’s a bit hard to find in supplement form, but is included in some soft chew formulas. (here’s one on Amazon as well)
3. Try a Colostrum Supplement for Your Dogue De Bordeaux

Found in mother’s milk, bovine colostrum helps support a normal histamine response to help improve allergies. Colostrum contains immunoglobulins (often referred to as antibodies) which help boost the performance of your Dogue De Bordeaux’s immune system. Canine colostrum supplements are a bit hard to find, but are included in some soft chew formulas. (here’s our favorite on Amazon Prime)
4. Add Reishi Mushrooms To Your Dogue De Bordeaux’s Diet
Reishi mushrooms contain ganoderic acid, which is a compound that inhibits the release of histamines. Histamines cause allergic reactions in your Dogue De Bordeaux’s body. In addition, this powerhouse ingredient has anti-inflammatory properties, which can help relieve itchiness. Reishi supplements for dogs are available on Amazon as well.
5. Try Giving Apple Cider Vinegar to Your Dogue De Bordeaux Topically or As a Dietary Supplement

ACV provides digestive support and relief for allergic reactions. A small amount can be put into your dog’s water bowl, or you can apply it topically. You can also apply a 50% mixture of ACV and 50% water directly to your dog’s skin in areas that are experiencing rash or itchiness. If given orally, you can also find apple cider vinegar soft chew supplements for dogs.
6. Try Giving Your Dogue De Bordeaux a Colloidal Oatmeal Bath
A popular remedy for people too, this age-old source of relief can also work for your Dogue De Bordeaux. See our review of our favorite oatmeal shampoos for dogs here.
7. Try Massaging Coconut Oil on your Dogue De Bordeaux’s Skin (or adding to their diet)
Coconut oil can be applied directly to your dog’s skin. It helps relieve itchiness and can also improve your dog’s skin and coat in general. Many dogs love the taste, which can actually become a bit of a problem if your pup licks it off their skin too quickly! We like the CocoTherapy brand of coconut oil made specifically for dogs.
8. Test if a Probiotic Makes a Difference for Your Dogue De Bordeaux
Scientists are finding many links between our digestive system and various diseases. Many pet owners notice a difference in their dog’s allergy symptoms after giving a canine probiotic supplement (make sure to use one made for dogs). Your results may vary, but it’s worth a try.
Many of the above ingredients are included in this 6-in-1 allergy and itch supplement for dogs, including salmon oil, reishi mushrooms, colostrum, apple cider vinegar, quercetin, and probiotics.
