Being a responsible dog owner involves understanding your furry friend’s health issues. One health condition dog owners should be aware of is canine hypothyroidism.

In this article, we’ll discuss the causes, symptoms, diagnosis, and treatment of this condition to keep your pet happy and healthy.

Understanding the Thyroid Gland in Dogs

To grasp the concept of canine hypothyroidism, it’s crucial to understand the role of the thyroid gland in your dog’s body. The thyroid gland, located near the trachea in your pet’s neck, regulates the body’s metabolic rate. The thyroid gland helps keep your pup energized and healthy when functioning properly. But what happens when this essential gland becomes underactive?

Causes of Canine Hypothyroidism

There are a few causes of hypothyroidism in dogs. The primary culprits are lymphocytic thyroiditis and idiopathic thyroid gland atrophy. Lymphocytic thyroiditis, an immune-mediated disease with genetic components, accounts for most cases of canine hypothyroidism. In some instances, the dog’s body attacks the thyroid gland, causing dysfunction. On the other hand, idiopathic thyroid gland atrophy involves the replacement of thyroid tissue by fat tissue. Another rare cause of hypothyroidism is thyroid cancer.

It’s essential to work with a veterinarian experienced in treating thyroid issues. In some cases, your regular veterinarian may refer you to a veterinary internal medicine specialist who can provide more in-depth examinations and treatments for your pet.

Symptoms of Hypothyroidism in Dogs

As the thyroid gland helps regulate various bodily functions, hypothyroidism affects many aspects of your dog’s overall well-being. Symptoms include weight gain, lethargy, cold intolerance, skin and coat issues, susceptibility to infections, and slowed heart rate. Neurological and reproductive symptoms and eye problems like dry eye may also occur.

Seeking help from an emergency vet in Orange County, CA, may be necessary if your pet exhibits severe symptoms that require immediate assistance. It is crucial to monitor your dog’s health and consult your veterinarian if you notice any unusual changes.

Diagnosing Canine Hypothyroidism

Diagnosing hypothyroidism in dogs typically involves blood tests, such as checking total thyroxin (TT4) levels, free T4 by equilibrium dialysis (Free T4 by ED), or conducting a thyroid panel. These tests determine if your dog has low thyroid hormone levels, which is indicative of hypothyroidism.

Vet lab testing is essential to veterinary diagnostics, as it helps veterinarians determine the best course of action for treating your pet. A reliable lab partner can ensure your dog receives accurate and timely diagnosis.

Treating Canine Hypothyroidism

Treating hypothyroidism in dogs involves oral administration of thyroid hormone replacement, such as levothyroxine. This medication is available in brand names like Thyro-Tabs Canine and Synthroid. Your dog must take this drug for the rest of their life to manage their condition effectively.

Determining the Proper Dose

Your veterinarian will start your dog on a standard dose based on their weight. After a month, they’ll retest your pet’s thyroid hormone levels to ensure they’re within a normal range. Keep in mind that your dog’s tolerance for the thyroid medication may change over time, requiring dose adjustments.

Risks of Over- or Under-Dosing Thyroid Medication

Monitoring your dog’s health while on thyroid medication is crucial, as an inappropriate dosage can lead to complications like hyperthyroidism. This condition manifests through hyperactivity, weight loss, and increased water consumption. Make sure to work closely with your veterinarian to keep your dog’s thyroid levels in check.

To End

Understanding canine hypothyroidism is essential for dog owners who want to provide the best care for their beloved pets. By recognizing the symptoms, working with your veterinarian on diagnosis and treatment plans, and staying vigilant about medication dosages, you’ll be one step closer to ensuring your dog’s long-term health and happiness. Don’t hesitate to contact a qualified veterinarian if you have concerns or suspect your pet suffers from hypothyroidism.
