When your dog is diagnosed with hypothyroidism, this may come as a surprise, like many pets, including dogs, don’t show symptoms of this condition right away. A few signs may indicate a thyroid disease, such as weight gain, hair loss, and other symptoms that your veterinarian may detect during a check-up, blood work, and tests. And, finding the best dog food for hypothyroidism can be concerning.
Dog hypothyroidism is a common condition in many dogs, which is more common in certain dog breeds, such as the Golden Retriever, Irish Setter, Cocker Spaniel, Miniature Schnauzer, and German Shepherd.
There are two main types of hypothyroidism in dogs. Primary hypothyroidism or autoimmune thyroiditis occurs when your pet’s body doesn’t recognize the thyroid gland and instead considers it a threat to the body.
In this process, your dog’s body creates antibodies to attack the cells in the thyroid gland, which results in tissue scars and disables the thyroid’s function. This type of hypothyroidism is the most common type of this condition in dogs.
Dog hypothyroidism is also caused when the hypothalamus, thyroid, and pituitary glands aren’t working correctly, which means the thyroid isn’t receiving the signals required to function well. When the pituitary doesn’t produce sufficient thyroid-stimulating hormones, the thyroid cannot work efficiently. While the thyroid itself isn’t damaged, it fails to function when other glands in the body don’t communicate, which results in hypothyroidism.
In both types of hypothyroidism, it’s essential to seek professional advice from your veterinarian, including continuous monitoring, testing, and prescribing thyroid medication.
Canine hypothyroidism is a common thyroid problem that can be treated successfully with veterinary medicine, regular exercise, and a well-balanced diet.

Best Dog Food for Hypothyroidism Frequently Asked Questions
How do veterinarians treat dogs with hypothyroidism?
Levothyroxine sodium is a standard treatment that helps dogs with an underactive thyroid. This medicine helps treat thyroid hormone deficiency and may relieve other conditions that impact the liver, brain, muscles, and kidneys. It’s also commonly used to prevent certain types of tumors caused by thyroid disorders.
What happens if my dog doesn’t receive treatment for hypothyroidism?
Dogs with hypothyroidism will experience weight gain, muscle weakness, and related discomfort due to these changes. Thyroid disorders can also lead to hair loss, anxiety, sluggishness, and a lack of activity.
Without a balanced diet and medical treatment, dogs with this thyroid condition will struggle with fatigue, slowed heart rate, sensitivity to heat or cold, and joint pain. For this reason, it’s essential to consult with a vet if any symptoms reveal the possibility of thyroid issues.
Which foods should I avoid feeding my dog?
Dogs with hypothyroidism tend to gain weight due to the metabolism slowing down. A diet high in fat, salt, and fillers such as grains, corn, and soy can increase weight gain and slow the progress of your dog’s medical treatment, even if they are generally active and exercise often. Ideally, it’s best to choose formulas with lean protein, lots of vegetables and fruits, omega fatty acids, and no grains or excessive sodium.
Can anxiety or changes in mental function be a sign of hypothyroidism in dogs?
Signs of stress in a dog may be caused by various conditions, including factors that are non-health related, such as moving to a new home or introducing a new pet into the household. Consistent stress or anxiety may be a sign of hypothyroidism, especially if there are other changes in your dog’s behavior, including weight gain, fatigue, and hair loss.
Is there a natural way to treat hypothyroidism in dogs?
There may be some health supplements and natural treatments that improve your dog’s thyroid function and metabolism, though it’s best to consult with a veterinarian to ensure they are safe.
