Your pet’s endocrine system. It’s not something we think about every day, but it plays such a vital role in your pet’s overall health. As pet parents, we often start to notice the little things: extra shedding, that patch of dry skin that suddenly appears, your typically cuddly furkiddo suddenly is anxious or withdrawn, they drink too much water, their coat is no longer glossy. All of these could be possible signs of a hormonal imbalance.
These could be possible signs of a hormonal imbalance
Once we start to notice these signs and dig around to find out more about them, many questions arise about the subject. Questions such as “How does the endocrine system work?” and “What exactly happens when it’s disrupted?”, “How can I support my furbaby?” and “Is there a natural way to support them?” are frequently asked by our pet parents, and today, we are here to discuss these questions.
What is the Endocrine System?
To put it simply, the endocrine system is a network of glands.

Your pet’s endocrine system has an important job to produce and release small chemical messengers known as hormones that travel through the bloodstream and target cells or organs. These hormones influence various bodily functions and processes, such as immune response, metabolism, mood, growth, and skin health. Some hormones act only on a single tissue, while others affect every body cell.
Common Endocrine Disorders in Pets
The most common endocrine disorders in dogs and cats include:
- Hypothyroidism, which is a lack of thyroid hormone. Vets divide this disease into two categories: congenital (present at birth) and acquired. It is common in dogs and rare in cats.
- Hyperthyroidism, caused by the overproduction of hormones made by the thyroid gland found in the neck region, and most commonly found in cats, rare in dogs.
- Cushing’s disease or Hyperadrenocorticism is when the adrenal glands overproduce cortisol, which can put a dog (or cat, though this is rare) at risk of several severe conditions and illnesses, from kidney damage to diabetes, and can be life-threatening.
- Addison’s disease or Hypoadrenocorticism is when the adrenal glands become deficient in producing hormones, which are essential to life, and changes in them can cause serious risks to your pet’s life.
- Diabetes is a common disorder characterized by elevated blood glucose (blood sugar) levels that affect how the body turns food into energy. It can be divided into two types: Type I (insulin-dependent) or Type II (noninsulin-dependent)
Let’s Talk About Skin and Mood
A pet’s skin and coat are a mirror of their internal wellness. Endocrine imbalances often first appear here. In dogs, for example, hypothyroidism and Cushing’s disease can lead to dry, flaky skin, brittle hair, thinning fur, bruising, and secondary skin infections. Hyperthyroidism can lead to greasy or matted fur, patchy hair loss, and excessive grooming in cats. Diabetes can lead to dull coats, dandruff, and skin issues that are slow to heal.

Hormonal imbalances can significantly affect your furbaby’s mental well-being, as they might present as lethargic or with a “sad” expression (such as dogs with hypothyroidism), anxious, hyperactive, or aggressive (like in cats with hyperthyroidism), or irritable, clingy, and depressive (such as in pets with diabetes or adrenal disorders). Pet parents may mistake this for aging, stress, or anxiety. However, these changes can result from hormonal fluctuation.
Natural Support is here!
While many endocrine issues require medical management, holistic support plays a key role in easing symptoms, protecting organs, and improving your furkiddo’s quality of life. A part of this is offering a diet that is high in protein, low in carbohydrates, and avoiding heavily processed diets. Many recommend home-cooked meals, which can provide balanced nutrition if done correctly. NHV offers personalized nutritional support, tailored to your furkiddo’s particular needs and conditions.
Herbal Supplements for Pets with Endocrine Disorders
Adding some gentle, vet-formulated herbal supplements can be very helpful in supporting your pet’s endocrine system without any harsh side effects. NHV Natural Pet Products offers a wide variety of natural support that is safe and gentle for your furkiddo to take for long periods of time:
- NHV Resthyro supports hyperthyroidism by balancing hyperactivity, supporting thyroid function, reducing stress and irritability, and helping strengthen the heart.
- NHV Thyro-Up supports hypothyroidism by balancing the thyroid and maintaining a healthy metabolism. It contains iodine-rich Kelp and Eleuthero, which could help stimulate the underactive thyroid gland.
- NHV Supraglan is our vet-formulated Cushing’s support, formulated with ingredients that help balance the endocrine system. It could help regulate adrenal gland function, has anti-inflammatory effects, and helps balance liver function.
- NHV Mellit is formulated with all-natural ingredients to help furkiddos with diabetes mellitus and support pancreatitis. It could help regulate blood sugar levels, promote the regeneration and functional recovery of B cells, and protect the kidneys, liver, and pancreas.
Supporting the Organs during Endocrine Disorders
Other forms of natural support come from supplements such as NHV Milk Thistle, which offers liver and kidney support that can be beneficial as the liver metabolizes most hormone medications. Milk Thistle could help reduce liver strain.

To give furkiddos the support they need to maintain a healthy coat, eyes, joints, and overall organ function, NHV PetOmega 3 contains omega-3 and omega-6 fatty acids that help maintain a proper balance and improve health. It supports healthy cell growth, could help improve skin condition, and is recommended for renal and kidney support.
The Importance of Nutrition
NHV Probiotics and Prebiotics support a healthy gut flora, which in turn helps balance and support a healthy immune system. This could help lower stress and anxiety and help support nutrient absorption. This is rather useful for furkiddos with Hyper- and Hypothyroidism.
Supporting the balance of good bacteria through probiotics and prebiotics is one of the kindest and most proactive things you can do for your furbaby’s well-being. This will not just be beneficial for their digestion, but for their immune response, their vitality, and even their emotional balance. While supplements offer safe, organic, natural support, each pet is unique. NHV Multi Essentials could help reduce lethargy in dogs with hypothyroidism and could support a healthy metabolism. It is useful for nutrient absorption as it is rich in vitamins and minerals that could be used as a great support along with NHV Thyro-Up.
Another gut-friendly support can be found in NHV TumFlora, which contains highly nutritious herbs to help your furbaby heal. The gentle defense against microorganisms and anti-fungal properties could aid the body in fighting off infections. Finally, it could help to relieve stomach cramps and indigestion and help with overall discomfort.
Take the time to understand their individual and dietary needs. With patience, consistency, care, and love, you’ll give their gut the gentle boost it needs to thrive and live a long, healthy, happy life.
Ready to Support Your Pet’s Endocrine Disorder?
Our furkiddos can’t speak directly to us
Our furkiddos can’t speak directly to us. They can’t tell us when something feels off or when they don’t feel good, so it’s up to us to notice those subtle changes in their behaviour and take action. Understanding how your pet’s endocrine system works and how it can affect everything from their skin and coat to their mood and organ health empowers us to advocate better for our furkiddos’ well-being. With the right combination of vet care, nourishing nutrition, and gentle support from NHV Natural Pet Products, we can help them feel more comfortable, vibrant, and loved at every stage of life. After all, their health is just about adding years, but it is also about adding a good quality of life to those years.

Natural Support for Thyroid Problems in Dogs and Cats
Hypothyroidism (underactive thyroid) is a condition that affects many pets, including dogs and cats. Apart from slowing down, if you notice that your little one’s fur is thinning, their skin is dry and dull or they have sudden weight gain, you may want to book a visit with your vet to run some tests, including a TT4 test, which is a measurement of thyroid hormone levels in the blood.
For pets suffering with hypothyroidism, we'd suggest adding natural pet thyroid supplements like our Thyro-Up and Multi Essentials to support their glandular system as well as support their metabolism.
How NHV Supplements Provide Glandular Support And Aid Digestion
Hypothyroidism can cause a lot of discomfort for your pet. If left untreated, hypothyroidism may lead to secondary health issues like cardiovascular disease. Ingredients like eleuthero and ginkgo support healthy thyroid function, and brain function. Kelp is rich in iodine which helps activate the thyroid gland while ingredients like licorice and gotu kola contain many beneficial properties for stimulating thyroid hormone production. The antioxidant and sedative properties in Thyro Up help to protect the body from cell damage, and help to soothe inflammation and discomfort. Multi Essentials contains a range of vitamins, minerals and trace elements that are formulated to help stimulate metabolism, promote healthy skin/coat, improve digestion, energy levels and help to fill nutritional voids.
