The most common endocrine hormone disorder in dogs is hypothyroidism. The body's thyroid hormone concentrations are low, resulting in this disorder.
The butterfly-shaped gland in your dog's upper neck produces thyroid hormones that control metabolism and, therefore, body temperature.
Dog hypothyroidism is characterized by hair loss, dry coats, fever, skin infections, obesity, and lethargy. Dogs with hypothyroidism may seek heat and warmth because they feel cold.
Hypothyroidism is more common in older or middle-aged dogs. 90% of hypothyroid dogs suffer from idiopathic atrophy or autoimmune distraction of their thyroid glands. In humans, this condition is like Hashimoto's thyroiditis.
The condition cannot be prevented, but your dog can live a healthy life once it has been diagnosed and treated.
A general list of breeds predisposed to hypothyroidism includes:
- Golden Retriever
- Irish Setters
- Doberman Pinschers
- Cocker Spaniels
- Miniature Schnauzers
- Airedale Terriers
How is Hypothyroidism Diagnosed?
The only way to diagnose hypothyroidism is by ordering a blood test from your veterinarian.
Hypothyroidism in dogs is always treated with lifelong prescription medications and regular monitoring by your veterinarian.
Holistic approaches can help your dog return to health, but there are no natural remedies or over-the-counter medications that can replace hormone supplementation from a veterinarian.
What are the Signs of Hypothyroidism?
It is common for virtually every organ in the body to be affected by a slowdown in metabolism.
Dogs with hypothyroidism usually exhibit one or more of the following signs:
- Gaining weight without increasing appetite
- Lack of motivation to exercise and lethargy
- Intolerance to cold (gets cold easily)
- Hair that is dull, dry, and shedding excessively
- Hair coat that is very thin to nearly bald
- An increase in dark skin pigmentation
- Skin and ear infections are more likely to occur
- Hair does not grow back after being clipped or shaved
- A high cholesterol level
- The heart rate is slow
Some dogs also have other abnormalities such as:
- Thickening of the facial skin, giving them a tragic expression
- Nerve dysfunction causing non-painful lameness, lack of coordination, and a head tilt
- Infertility and loss of libido in intact males
- An inability to conceive, infertility, and abortion (miscarriage) in females
- The corneas of the eyes contain fat deposits
- Keratoconjunctivitis sicca (KCS) or dry eye is caused by inadequate tear production
Can Hypothyroidism Be Treated?
Hypothyroidism can be treated, but it cannot be cured. Thyroid replacement hormone is administered orally.
The dog will have to take this drug for the rest of its life. In most cases, levothyroxine is chosen as the preferred treatment (brand names include Thyro-Tabs® Canine, Synthroid®).
When to Contact Your Veterinarian
Consult a veterinarian if you suspect your dog has hypothyroidism before adding any supplements or changing her diet.
Your dog's medication dosage will vary after a hypothyroidism diagnosis, so it's important to monitor this condition by having blood work done every six to twelve months.
Your veterinarian will discuss whether your dog's thyroid hormone needs to be increased or decreased based on the results of his blood work.
Even if your dog seems to be feeling better, she will need prescription medication for the rest of her life.
Hypothyroid symptoms vary between dogs, so you should only choose potential solutions that support your dogs individual’s individual symptoms.
Below are some of the most common hypothyroid symptoms that healthy nutrition and supplementation may help improve.

Prescription foods - As opposed to a standard AAFCO balanced diet, prescription weight loss foods are formulated to provide more nutrients in a lower calorie food.
By feeding a low-calorie diet to your dog, you can give him the nutrition he needs without sacrificing his weight. It is sometimes necessary to feed your dog prescription foods until its thyroid is properly treated and medicated.
Non-prescription foods - Depending on the results of your dog's bloodwork, you may be able to transition your dog to a food formula that meets the caloric needs of a typical dog with a normal metabolism after he responds well to medication.
Mix ¾ Kibble and ¼ Raw - Introducing wet or raw food into her diet may help her slim down if she is currently eating kibble and having trouble losing weight. Both types of food are low in carbohydrates, and eliminating carbohydrates leads to weight loss.
In particular, raw food can help your dog get nutrition similar to what its ancestors might have consumed. In addition, it contains high-quality meat, plenty of moisture, and fewer carbohydrates.
