Why the Thyroid Matters

The body functions within a delicate balance, dictated by various signaling mechanisms within. Hormones play a large portion in maintaining this balance, functioning as a signal between organs as to how to regulate various functions.

The thyroid gland, located in the neck, is a vital player in maintaining appropriate metabolic function in almost all of the body’s tissues. Over or under production of the thyroid hormone that it secretes can have dramatic effects. Thyroid problems in the dog generally result in:

Hypothyroidism – This is the underproduction of thyroid hormone, resulting in a slow metabolism and corresponding signs. This is the most common thyroid problem in dogs.

Hyperthyroidism – Increased thyroid hormone production results in increased metabolic rate and resulting consequences on the body’s organs. Hyperthyroidism is rare in the dog and when seen is usually a result of over-treating low thyroid hormone.

Signs of Thyroid Problems in Dogs

When the thyroid gland is not functioning properly, it shows. Almost every organ in the body is affected by thyroid hormone. Classically, dogs with low thyroid hormone will show one or more characteristic signs:

  • Weight gain/difficulty losing weight
  • Sluggishness
  • Skin problems (infections, hair loss, thick skin)
  • Heart problems
  • Neurological issues
  • Eye problems

A pet who has one or more of these symptoms should be tested for thyroid hormone deficiency.

Animals who suffer from increased thyroid hormone, or hyperthyroidism, often experience weight loss, ravenous appetite, panting, digestive problems, blood pressure abnormalities, and heart issues. Hyperthyroidism in the dog is rare, but very common in the cat.

Dealing with Thyroid Trouble

If our pet experts at Seven Hills Veterinary Hospital suspect that a pet’s thyroid may not be functioning correctly, we may recommend blood testing in order to evaluate further. The thyroid is a complex organ, and many times several types of blood values must be obtained in order to make a diagnosis.

If your dog is diagnosed as hypothyroid, hormone supplementation usually in the form of a twice-a-day pill is often recommended. Most dogs respond very well to this treatment. Blood work is monitored periodically in order to ensure correct dosing.

An over- or under-active thyroid can cause a world of problems for affected pets. Thankfully we are able to diagnose and effectively treat most thyroid problems in dogs. If you think that your pet may have a thyroid problem, we would be happy to discuss with you further. Please give us a call so we can get started helping your pet right away.
