Quercetin For Dogs:
Natural Allergy Relief For Itching & Scratching


A Natural Antihistamine For Dogs

Allergies can make dogs feel miserable, causing constant scratching, chewing, licking, hot spots and hair loss. Many dogs end up wearing the "cone of shame" during allergy season to prevent them from chewing themselves raw. To stay comfortable, some dogs rely on steroids, antibiotics and antihistamines, but these medications can have long-term side effects. That's why many dog owners look for a natural anti-histamine to give their dog relief. Natural options like quercetin offer relief without adverse effects.

Quercetin is a bioflavonoid that provides natural allergy relief for dogs reducing symptoms like itching, scratching, licking and chewing. Many veterinarians suggest quercetin because it is a safe, natural antihistamine for dogs. In fact, quercetin is often referred to as Nature's Benadryl.

How Quercetin Eases Dog Allergy Symptoms

Quercetin, a natural bioflavonoid, works by suppressing histamine production and reducing inflammation, making it ideal for dogs with seasonal or environmental allergies. When dogs encounter allergens, their bodies produce histamine, triggering itching, redness, and swelling. By turning off this response, quercetin offers long-lasting relief from symptoms such as scratching, chewing, and hot spots. Follow dosage instructions based on the product's potency and your dog's weight.

While conventional treatments like steroids and antihistamines provide temporary relief, symptoms often return once the medication is stopped. Quercetin offers a natural solution for long-term allergy relief by supporting immune health.

How Can Quercetin Provide Natural Relief For Dog Allergies?

Quercetin is derived from colorful fruits and vegetables such as blueberries, apples, and leafy greens, making it a gentle, all-natural remedy for dogs. Studies indicate that quercetin not only reduces histamine but also has anti-inflammatory properties that can alleviate skin irritations, hot spots, and other allergy symptoms in dogs. By reducing dependency on prescription antihistamines or steroids, quercetin supports your dog’s immune system and overall health.

Allergy Induced Mast Cell Tumors (MCTs)

In addition to relieving seasonal and environmental allergies, quercetin may benefit dogs prone to mast cell tumors, which are the most common type of skin cancer found in dogs. These tumors can appear on the limbs, in between toes or even in organs like the spleen and liver. Mast cells release histamine and other chemicals into surrounding tissues, causing side effects such as digestive issues, skin rashes, and shortness of breath. By naturally managing histamine production, quercetin could help ease these symptoms and support immune health.

Common Allergic Reactions in Dogs

An allergy is when your pet's immune system overreacts to a trigger such as pollen. When pets have allergies, their immune system makes substances called antibodies that identify a particular allergen (e.g. dust) as harmful and responds to it. This can cause your pet's skin to become inflamed, itchy and red. The best way to protect your dog from an allergic response is to make sure your pet avoids the allergen, but it can be difficult to identify the allergen.

  • Seasonal Environmental Allergies - Some of the most common causes of seasonal environmental allergies in dogs include dust, dust mites, mold, pollen and grass. These irritants are more prolific during certain times of the year, such as spring and summer.
  • Flea Allergy Dermatitis (FAD) - Flea allergy dermatitis occurs when a dog's immune system is hypersensitive to the antigen or protein in the flea saliva. One flea bite can cause intense itching that can last for days.
  • Food Allergies - Dogs can be allergic to certain foods such as beef, poultry and grains. Feeding a low carbohydrate novel protein diet is helpful for most dogs with allergies. Please include your dog's diet and treats on the order form at checkout and Ask Ariel will provide diet tips for your dog on the packing slip that comes with your order.
  • Other Environmental Allergies - Dogs can also have allergic reactions to many household chemicals, mold and mildew. Scented candles, laundry detergent and dander from other pets can be allergens too. Pets are much more sensitive to airborne particulates, and the exposure can cause breathing problems.

Is Quercetin Safe for Dogs?

Yes, when administered at the appropriate dosage, quercetin is deemed safe for dogs. Many holistic veterinarians recommend quercetin for dogs with allergies because of its safety and efficacy. To administer to your dog, give with meals either in capsule form or by mixing into food. Here are a few things to consider when selecting a safe and effective quercetin supplement for your dog:

  • Look for a product that is third-party tested for purity.
