Primalix TSH Thyroid Stimulating Herbs for Hypothyroidism in Dogs  - 4 oz

A dog's thyroid gland produces the hormones liothyronine (T3) and levothyroxine (T4), which regulate his metabolism. When the thyroid doesn't produce enough thyroid hormone, the dog is considered hypothyroid, the most common hormonal deficiency in dogs.

An insufficient thyroid hormone level can affect many of a dog's bodily functions. With conventional veterinary treatment, the prognosis is favorable for a hypothyroid dog, though he will likely require life-long management of the disease since conventional medicine destroys the thyroid.

On the other hand, with natural herbal treatment (whether with your holistic veterinarian or just you and your dog in the comfort of your home), the thyroid gland can be nourished and balanced, and according to clinical findings may well be restored to normal function.

Most Susceptible Breeds

Any dog can have hypothyroidism, but medium to large breed dogs tend to develop the condition more frequently. Some breeds are predisposed to hypothyroidism, including

  • Golden retrievers
  • Irish setters
  • Labradors
  • Boxers
  • Poodles
  • Cocker spaniels
  • Doberman pinschers
  • Old English sheepdogs
  • Miniature Schnauzers
  • Dachshunds  

Symptoms to watch for

Because thyroid hormone affects the function of different organs, there are many of symptoms of hypothyroidism. One of the most common and obvious signs of insufficient thyroid-stimulating hormone (TSH) is a lackluster, dull coat.

  • A dog may also lose fur particularly in his undercoat and around his tail, leading to a bald, "rat-tailed" appearance
  • Some dogs have an excessively oily coat, leading to scaly skin and a stinky odor
  • Others develop brittle fur, causing the hairs to break off
  • Weight gain to the point of obesity is common due to slower metabolism making the dog lethargic
  • Other symptoms include broken and infected toenails, skin infections, lowered heart rate and cold intolerance

What causes Hypothyroidism in dogs?

Hypothyroidism is usually an autoimmune response resulting in wasting of the thyroid gland or the destruction of its tissue by the dog's own immune system. Some dogs are born with hypothyroidism while others develop it from insufficient iodine. Occasionally, medical treatment including surgery affects the gland's function.

Often the cause is idiopathic or unknown.  The disease tends to present around six years of age. Academically it can be helpful to understand the cause of hypothyroidism, but knowing the root of the problem isn't necessary for treatment. 

Diagnosing the condition

Diagnosing hypothyroidism isn't as straightforward as running a blood test to examine hormone levels. The vet will need to account for medical history, symptoms and conduct a thorough exam, perhaps even using x-rays to look for physical abnormalities on the thyroid gland.

Blood testing is helpful for determining the levels of T3 and T4. However, low levels of the thyroid hormone don't necessarily indicate hypothyroidism. T3 levels can fluctuate into the normal range for hypothyroid dogs, and dogs taking corticosteroids and seizure medications may have lower T4 levels.

Sighthounds such as greyhounds and whippets can be challenging to diagnose as they tend to have naturally low levels of T4 - up to 50 percent lower than other breeds. Other thyroid tests include a thyroid-stimulating hormone (TSH) test and the antithyroglobulin antibodies (TGAA) test. Like the other blood tests, these also can be inconclusive.

Conventional veterinary treatment

It's common for a vet to prescribe a test medication if hypothyroidism can't be conclusively confirmed. The dog takes medicine up to several months to see if his condition changes and his symptoms subside. Whether the dog is on a trial run or is being treated definitively for hypothyroidism, he'll be taking a synthetic form of thyroid hormone such as l-thyroxine. Since the dog is taking the medication as a test to see how favorably he responds to treatment, the vet will need to check T4 levels regularly to ensure the dog isn't getting too much of the hormone. 

Is conventional treatment best for your dog?

If the dog is being treated for confirmed hypothyroidism, he'll likely take the medication for the rest of his life. As well, he'll need to have his blood tested regularly to ensure his T4 level is appropriate. Too much thyroxine can result in organ damage, with symptoms such as

  • drinking too much water
  • increased urination and appetite
  • irregular pulse and heart rate
  • restlessness and weight loss

The vet will also rely on regular blood tests to determine if the dosage should change. Adjusting the medication without consulting a vet can complicate your dog's condition. 

Thyroxine has potential side effects including interfering with the thyroid gland's normal hormone production to the point where it stops producing hormones altogether. A dog may respond by being irritable, hyperactive or more aggressive.

Our Herbal Constellation


Bladderwrack (Fucus Vesiculosus) is a variety of kelp that medical practitioners, both ancient and contemporary, have prized for its thyroid stimulating properties. This iodine-rich herb feeds a dog's under-performing thyroid and boosts overall metabolism.

Our proprietary extraction process gives you more of Bladderwrack's holistic spectrum of nutrients including calcium, magnesium, potassium, sodium, sulfur, silicon, iron and an assortment of B-complex vitamins.

Coleus Forskohlii root has been used for thousands of years in Hindu and Ayurvedic traditional medicine. The roots of this botanical contain the active constituent forskolin. Today's clinical studies of forskolin extracted from Coleus Forskohlii root and administered to dogs with hypothyroidism confirm the regulated increase in thyroid hormone secretion. See Haye B, Aublin JL, Champion S, et al. Chronic and acute effects of forskolin on isolated thyroid cell metabolism. Mol Cell Endocrinol 1985;43:41-50. Also Roger PP, Servais P, Dumont JE.

USDA Certified Organic

Echinacea angustifolia root is a natural antibiotic without the adverse side effects of prescription drugs. This popular herb is an alterative, which is a class of plant that supports the removal of cellular waste while maintaining healthy uptake of nutrition at the cellular level.

Astragalus membranaceus root has been used in Traditional Chinese Medicine (TCM) for thousands of years. It is an adaptogen, which helps fortify the body against damage caused by physical, mental and emotional stresses.

Black Walnut Hull is a popular anthelmintic, which safely and effectively kills internal parasites. But it is also safe and effective as a hormone-activating, thyroid stimulating herb for dogs due in part to its high organic iodine content which feeds the thyroid.

Turn Ordinary Food Into Functional FoodSM

Our Primalix® TSH Thyroid Stimulating Herbs for Dogs with Hypothyroidism - Functional Food Drops - let you add specific, beneficial, physiologically active food components (herbal nutrients) to wet or dry food.

Functional food is any food having health-promoting or disease-preventing properties beyond the basic function of supplying nutrients.

Nearly 2500 years ago Hippocrates said, “Let food be thy medicine and medicine be thy food.”

Animals do this instinctively. In the wild they “functionalize” their food by sniffing out and eating specific herbs to prevent disease and maintain natural wellness.

Now you can add function to any dry, canned, raw or homemade pet food. Give your domestic dog or cat a targeted dose of wild, natural wellness with every meal.
