Hypothyroidism in dogs is a disorder where the thyroid gland in the neck doesn’t secrete enough thyroxine, a hormone that controls metabolism. This means that a dog’s body is no longer able to convert food into fuel at an appropriate rate.

Though causes and symptoms may vary, treatment is the same for most dogs. Symptoms can range from lethargy and weight gain to seizures and heart problems.

Age, breed, lifestyle, and exposure to certain substances can all influence the onset of hypothyroidism in canines. If you see the signs in your dog, then you must consult your veterinarian to find the best treatment options.

Here’s what you should know about hypothyroidism in dogs.
