Jack Russells are energetic dogs, but allergies can leave them dealing with itchy skin, scratching, and irritation. While it’s important to work with your veterinarian to identify the cause of your dog’s symptoms, certain natural ingredients may help support healthy skin, a balanced immune response, and relief from occasional itching.
Best Natural Allergy Remedies for Jack Russells
1. Give Your Jack Russell a High Quality Fish Oil Daily
2. Try Adding Quercetin To Your Jack Russell’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 it is included in some soft chew formulas. (here’s one on Amazon as well)
3. Try a Colostrum Supplement for Your Jack Russell
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 Jack Russell’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 Jack Russell’s Diet
Reishi mushrooms contain ganoderic acid, which is a compound that inhibits the release of histamines. Histamines cause allergic reactions in your Jack Russell’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 Jack Russell 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 Jack Russell a Colloidal Oatmeal Bath
A popular remedy for people, too, this age-old source of relief can also work for your Jack Russell. See our review of our favorite oatmeal shampoos for dogs here.
7. Try Massaging Coconut Oil on your Jack Russell’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 Jack Russell
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 can be found in this 6-in-1 allergy and itch supplement for dogs, including salmon oil, reishi mushrooms, colostrum, apple cider vinegar, quercetin, and probiotics.
