Amazing Product!!

"This product is AMAZING! My 12 year old Border Collie mix develops bad seasonal allergies at the end of the summer from yellow weed that grows along our farm fencing. We tried so many different products with no success over the years, he would chew his paws so bad. We used Harmony last summer and it worked amazingly! I HIGHLY recommend this product!!"

Healthy Skin From Healthy Organs

Skin problems aren’t just skin-deep - they can be a sign that your dog's organs aren't healthy. Harmony is an exciting formulation that targets the root cause of seasonal and environmental allergies.

  • Supports a normal histamine response: Itchy skin is caused by histamine release. Harmony contains L-theanine, liposomal quercetin and Chinese skullcap to help regulate the mast cells and histamine release.
  • Supports normal detoxification: Organic broccoli sprouts initiate Phase II liver detoxification and spirulina helps detoxify the skin from everyday toxins.
  • Supports healthy thyroid function: Organic Irish moss supports healthy thyroid function and helps detoxify from heavy metals.
  • Veterinarian formulated: Formulated by a holistic veterinarian for maximum safety and benefit.

Premium Ingredients

Organic broccoli sprouts
Organic broccoli sprouts

Broccoli sprouts are rich in sulforaphane, a compound that can help mitigate the effects of seasonal or environmental allergies by reducing oxidative stress supporting a normal inflammatory response. Sulforaphane also activates Phase II liver detoxification, which can help clear allergens from the body more effectively, supporting overall health and healthy skin.

Organic Irish moss
Organic Irish moss

Irish moss, also known as Chondrus crispus, supports the digestive and immune systems, thanks to its rich nutrient profile, including vitamins, minerals, and antioxidants. Its mucilaginous content helps soothe the digestive tract, which is crucial for maintaining a strong immune response against allergens.

Liposomal quercetin
Liposomal quercetin

Quercetin is a potent flavonoid antioxidant that supports skin health by neutralizing free radicals. It also promotes a normal inflammatory response. Liposomal quercetin offers superior bioavailability compared to other forms of quercetin due to its innovative delivery system. By encapsulating quercetin in natural phospholipids, it ensures that the quercetin is protected as it travels through the digestive system, and allows it to more easily pass through the cell membranes. This enhanced delivery mechanism means that the body can utilize quercetin more effectively, maximizing its skin benefits.

Organic Chinese skullcap
Organic Chinese skullcap

Chinese skullcap (Scutellaria baicalensis) contains bioactive compounds like baicalin, which support dogs with seasonal or environmental allergies by maintaining a normal histamine response.

Organic cat's claw
Organic cat's claw

Cat's claw, derived from the Uncaria tomentosa vine, contains tannins and sterols to support healthy skin and a normal histamine response in dogs with seasonal or environmental allergies. Moreover, cat's claw's antioxidant effects can help protect cells from damage caused by free radicals, contributing to overall health and resilience against allergens.

Spirulina
Spirulina

Spirulina is a blue-green algae that's rich in proteins, vitamins, and minerals and antioxidants. Antioxidants can help balance the allergic response by neutralizing free radicals and supporting the immune system. Additionally, spirulina can support a healthy gut, which is closely linked to immune function and may further help in managing allergic reactions in dogs.

L-theanine
L-theanine

L-theanine, an amino acid found primarily in green tea, can help promote relaxation and reduce stress, which is often a trigger for itchiness in dogs with seasonal or envirmental allergies. It has a calming effect on the nervous system and can support a more balanced immune response to allergens.

Organic nettle
Organic nettle

Nettle (Urtica dioica), is a plant with a long history of health benefits. It supports a healthy inflammatory and histamine response and assists natural detoxification processes.

Organic marshmallow root
Organic marshmallow root

Marshmallow root is renowned for its mucilaginous properties, which bolster the gut lining. Its ability to promote healthy mucus secretion helps support overall gut health and aids in the integrity of the mucosal lining.

Who We Are

In Memory of Simon & Aaron

The story of Four Leaf Rover started as a tragedy. Our founder Dana Scott lost two dogs from toxic sprays they were exposed to in the fields surrounding her home. In a frantic effort to save her dogs and protect her remaining dog family, Dana connected with most of the leading holistic veterinarians around the world about the most effective natural remedies. As Dana researched remedies, she found nearly all contained hidden or harmful ingredients. Four Leaf Rover began as a promise to Dana's lost dogs that all dogs deserve super premium products with natural ingredients that are thoroughly tested to be low in harmful pesticides and heavy metals. With a mission of quality, transparency and sustainability, Four Leaf Rover is making the world a better place for dogs and the people who love them.
