Hypothyroidism
Thyroid Supplements for Dogs
NHV supplements for hypothyroidism in dogs are natural supplements that can significantly improve your dog’s health when taken together with treatments prescribed by a veterinarian.
Dietary supplements such as Thyro UP can be used as part of a holistic support plan for maintaining thyroid function and improving your dog’s energy level while supporting weight management and metabolism.
About Canine Hypothyroidism
Two of the hormones the thyroid produces are T3 (triiodothyronine) and T4(thyroxine). Both of these hormones provide support for a dog's metabolic rate and assist with many other functions, including digestion, growth, muscle, bone, heart, cognition, and immunity. When your dog’s thyroid is not producing enough of these hormones, it can affect your pet’s daily comfort and well-being.
Dogs with hypothyroidism will need treatment for life. Adding vet-formulated and approved thyroid supplements can help further support your little one with thyroid-related symptoms. If you suspect that your pet may have hypothyroidism, a vet visit is highly recommended. Your vet will conduct the required blood work to diagnose the condition and give you advice about a good canine thyroid supplement.
Signs and Symptoms of Hypothyroidism in Dogs
The signs and symptoms may vary in pets with hypothyroidism, but often, your dog may show one or more of the following signs:
- Excessive shedding, dry skin, and infections
- Weight gain without an increase in appetite
- Lethargy - lack of interest in walks, exercise, and play
- Intolerance to cold - looking to lie in a warm place
- Depression and aggressive behavior
- Anxiety
- Seizures
- Infections
- Slow heart rate
Be sure to document these symptoms so your vet can prescribe the appropriate treatment and NHV thyroid supplements for your dog.
Most Commonly-Affected Dogs
Canine hypothyroidism is commonly detected in middle-aged dogs between the ages of 4 and 10 years. It can affect any breed of dog; however, it is rare in toy breeds. The dog breeds most affected are:
- Golden retriever
- Dachshund
- Doberman Pinscher
- Irish Setter
- Cocker Spaniel
- Miniature Schnauzer
- Airedale Terrier
- Labrador Retriever
- Shetland Sheepdog
- Greyhound
- Scottish Deerhound
Fortunately, while not curable, vet-recommended treatments and natural thyroid supplements for dogs can help with this health condition.
Causes of Hypothyroidism in Dogs
Hypothyroidism in dogs is caused by an underactive thyroid gland, resulting in decreased production of thyroid hormones. It is believed that 95% of hypothyroidism in dogs is caused by the autoimmune condition known as autoimmune thyroiditis , which is an inflammation of the thyroid gland due to its destruction by the body.
The other cause could be a tumor of the pituitary gland.
“Thyroid imbalances can be challenging, but with early recognition and integrative care, including veterinary support, appropriate medication, and natural supplements, many pets go on to live long, happy lives.
If you’ve been wondering, “Can pets develop thyroid issues?” the answer is yes, and understanding the thyroid imbalance causes in pets is the first step toward helping them feel their best.”
- Dr. Mehdi Esmatparast, DVM, Ph.D.
How to Treat Canine Hypothyroidism
The common allopathic treatment approach uses a synthetic hormone called Thyroxine . However, over time, the thyroid gland will stop producing the hormone on its own due to the gland's feedback system, indicating there is no need to manufacture it since the synthetic hormone is now taking over.
NHV’s thyroid supplements for dogs, together with diet and natural treatment prescribed by your veterinarian, can significantly improve your furbaby’s health. Canine thyroid supplements, such as Thyro UP , can be used as part of a holistic support plan if your pet is diagnosed with canine hypothyroidism. These supplements may help support thyroid function, improve your dog’s energy level, and support weight management and metabolism.

Frequently Asked Questions About Canine Hypothyroidism
How long until I see results after giving my dog thyroid supplements ?
Consistency is key. Our Pet Experts recommend giving your pet the appropriate dosage twice daily. It may take around four weeks to notice changes in your pet’s overall vitality, although every pet is different. As always, continue to check in with your veterinarian throughout their wellness journey.
Are canine thyroid supplements safe for my dog to take long-term?
NHV’s thyroid support supplements are formulated by a holistic veterinarian and master herbalist with over 50 combined years of experience in plant-based remedies. They are gentle and are designed for daily use as part of your dog’s ongoing wellness routine. If your dog is taking thyroid medication or other treatments, check with your veterinarian before adding any new supplement to make sure it’s appropriate for their individual needs.
Will I always need to get my dog’s thyroid checked?
At first, when you’re figuring out the right amount of thyroid support for your dog, your vet will probably check every month or so. Once you have a regime, they’ll likely check twice a year.
Is hypothyroidism genetic? Can I still breed my dog if they have it?
Hypothyroidism can have a genetic component, and some breeds are more predisposed to developing it than others. Because inherited thyroid disease may be passed on, breeding a dog with hypothyroidism should be discussed carefully with your veterinarian. Age, diet, and environmental factors may also influence thyroid health.
What if I don’t address my dog’s hypothyroidism?
Ignoring your dog’s hypothyroidism almost guarantees a harmful outcome for your furbaby. If it gets really bad, it could lead to a dangerous condition called myxedema coma, or even an early death.
Start treatment with your vet. NHV is always here for additional support with thyroid supplements for your dog.
Additional Support Tips
While thyroid disorders can’t always be prevented, especially when genetics or age play a role, there are ways to support your pet’s overall thyroid health.
- Feed a balanced, high-quality diet. Choose nutritious, minimally processed foods when possible, and work with your veterinarian if your pet requires an iodine-controlled or therapeutic diet.
- Add targeted thyroid support. For dogs with hypothyroidism, NHV Thyro-Up is veterinarian-formulated with herbs that support healthy thyroid function, metabolism, and overall vitality.
- Reduce unnecessary environmental exposure. Regularly clean pet areas, minimize heavily scented sprays and cleaners, and choose pet-safe products for bedding, toys, and household use.
- Support a healthy, low-stress routine. Regular exercise, enrichment, consistent routines, and quality time together can all help support your pet’s overall wellness and endocrine health.
Always speak with your veterinarian before introducing new supplements, especially if your pet is taking thyroid medication or other prescription treatments.
