Weimaraners are active, athletic dogs, but many owners find themselves dealing with persistent scratching, irritated skin, and allergy-related discomfort. Environmental allergens, seasonal changes, and food sensitivities can all contribute to itchy skin and excessive licking. While it’s important to work with your veterinarian to identify the underlying cause, certain natural ingredients may help support healthy skin, maintain a balanced immune response, and provide relief from occasional allergy symptoms.

Best Natural Remedies to Help Your Weimaraner Stop Itching
1. Give Your Weimaraner a High-Quality Fish Oil Daily
2. Try Adding Quercetin To Your Weimaraner’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 Weimaraner

Found in mother’s milk, bovine colostrum for dogs 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 Weimaraner’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 Weimaraner’s Diet
Reishi mushrooms contain ganoderic acid, which is a compound that inhibits the release of histamines. Histamines cause allergic reactions in your Weimaraner’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 Weimaraner 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 experience rash or itchiness. If given orally, you can also find apple cider vinegar soft chew supplements for dogs.
6. Try Giving Your Weimaraner a Colloidal Oatmeal Bath
A popular remedy for people too, this age-old source of relief can also work for your Weimaraner. See our review of our favorite oatmeal shampoos for dogs here.
7. Try Massaging Coconut Oil on your Weimaraner’s Skin (or adding it 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 Weimaraner
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.

Helping Your Weimaraner Find Relief From Allergies
Allergy management often requires a combination of proper veterinary care, a nutritious diet, and targeted supplements that support skin and immune health. Ingredients like omega-3 fish oil, quercetin, colostrum, probiotics, reishi mushrooms, and apple cider vinegar may help reduce itching and support healthier skin over time. By finding the right approach for your dog’s individual needs, you can help your Weimaraner stay comfortable, maintain a healthy coat, and spend more time enjoying life instead of scratching.
