Quercetin For Dogs With Allergies

Quercetin has been known to help dogs with allergies. I prefer it over Benedryl, and you can feed quercetin to your dog to stop them from scratching themselves.

If you’re looking for natural remedies for your itchy dog, then this post is for you.

What Is Quercetin?

It’s a plant-derived flavonoid present in fruits and vegetables such as:

  • apples (red)
  • berries
  • cherries
  • asparagus
  • bell peppers (green and yellow)
  • broccoli
  • brussels sprouts
  • cabbage
  • citrus fruits
  • kale
  • green tea 

It’s also an antioxidant that fights against inflammation reduces itch and allergy symptoms.  

Why Would You Feed This To Your Dog?

Essentially the reason you would feed this is if you were looking for natural methods to alleviate their allergy symptoms.  

When Not To Feed Quercetin To Your Dog

Don’t feed quercetin if your dog is:

Pregnant or lactating 

If your dog is on any medication for a serious medical condition it is best to consult with your vet. Hopefully, you have a vet who is well-versed in quercetin and not just conventional Western pharmaceuticals.

If you need a Traditional Chinese Medicine Veterinarian:

I use him for my own dogs, and refer clients to him when a TCVM vet isn’t available in your city.

What Kind Of Quercetin to Feed 

When you shop for quercetin, you will see it come as Quercetin or Quercetin Dihydrate.  

The key difference between quercetin and quercetin dihydrate is that quercetin is a plant flavanoid whereas quercetin dihydrate is a synthetic chemical compound.

Practically, this powder is insoluble in water. But it is soluble in alkaline solutions.  

It’s also bitter in flavor and found as a yellow crystalline powder.  

“Quercetin dihydrate is a chemical compound having the chemical formula C15H14O9. This substance is commonly found in quercetin supplements. It has the highest bioavailability among other ingredients. This substance also assures a better absorption of the supplement. However, it costs more than other supplement forms due to this quality of high absorption.”

It’s often sold in powder form and bright yellow in color.  

How Much Quercetin To Feed Your Dog?

Take your dog’s weight in pounds(lbs) x 1000mg

Divide the resulting number by 125

The resulting number will be the mg daily dosage required.

Then split the daily dosage in half.

Administer the half dosage two times a day with food.

Feed quercetin for no more than 12 weeks. Your dog’s allergies should be resolved by then and quercetin is not meant for daily use for the life of your dog.  

What Form To Buy It In?

Quercetin is best purchased as a powder so that you can dial back the dosage if you need to. A very small portion of dogs may get diarrhea from the supplement.

Sometimes quercetin is sold with bromelain to help with digestion simultaneously.  

Another variation is seeing quercetin combined with vitamin C. 

How To Feed It?

You can add it to their food and mix it in, or you can combine it with a thick food topper and fold it in because it won’t actually “mix” in well. You can watch a sample video here: 

When To Feed It?

Just before their meal or with food. 

Possible Side Effects?

Your dog may have diarrhea, reduced appetite or nausea.

How Soon Does It Work?

Quercetin stops the itch almost immediately. As long as your dog is on a natural diet, you will notice that your dog’s “itch” will be less right after you feed it to them.  

In some small cases, you may have to try another brand, or if you haven’t addressed the diet or have yeast issues you are tackling then the itch won’t be as fast to go away.

3 Top Things To Remember About Quercetin:

Quercetin supplements can quickly help reduce your dog’s itchy symptoms.

You can feed it from whole food, supplements, or whole food supplements.

Don’t feed it for more than twelve weeks at a time and be sure to address any underlying issues like yeast as well as feed a natural whole foods diet.

    Why can’t dogs take quercetin more than twelve weeks at a time? I am trying to give my dog a joint supplement which happens to have Quercetin in it.

    1. Hannah Zulueta

      Hi that is a very good question. It is a human supplement that is also now used for dogs. Long term use has not been studied and… it can be hard on the kidneys. https://pubmed.ncbi.nlm.nih.gov/29127724/

    Other articles I’ve read say to give Quercetin with no food, as it will work differently if taken with food. Can you clarify?

    1. Hannah Zulueta

      Hello Melissa,

      Thank you for your inquiry. You’ve raised a question I didn’t know the answer to. I have never heard that but ….that just means it hasn’t come across my horizon. I did go to pub med to search and could not find any studies, or double blind food trials that show if the immune system had a better response feeding Quercetin with no food vs. food.

      Keep in mind Quercetin is a polyphenol found in food. For example it’s in apples, berries, kale, tea, to name a few. What we’ve done is isolated this compound and when done so in a lab, we come up with Quercetin dihydrate
      Quercetin glucosides, Quercetin phytosome.

      And again, when I searched to see if there were any trials comparing this…. I didn’t find one.

      Among my holistic nutrition groups I haven’t been hearing on timing either (for dogs) but I will keep my ears open. We’re constantly evolving in what we know about ingredients and how it influences gene expression.

    I have been giving my 60+lbs dog 75mg of Quercetin once a day and it doesn’t seem to be helping. My vet wanted to do shots I’m not wanting that for him. Is there something else I can do?

    1. Hannah Zulueta

      Hello Kim. I didn’t see your comment it was buried between a lot of spam comments. I apologize. Allergies are never a one treatment one and done case. It’s multifaceted.

      Work with your vet and follow their treatment plan. And if you are called to trying a natural approach to support you with food, you can book a package with me or I can refer you to my TCVM vet who does phone consults.

      Thank you and blessings.
