A reader called for information about the thyroid. It seems that her dog obedience trainer told her that her dog's temperament could be caused by the thyroid. Then the next time she took her pet to the groomer, she was told that the poor coat could be caused by the thyroid.
The caller couldn't understand how one organ could affect both the personality and the coat quality. She felt that the poor thyroid was being used like we often use the term "flu" for a cold, bronchitis or pneumonia. Her question was, "How does the thyroid function and what are the consequences if it doesn't function?"
I had to do some digging since it has been a long time since I even thought about the thyroid. To answer the first question, yes, the thyroid can affect both the personality and coat quality.
In regards to how the thyroid functions and the consequences if it doesn't function, let's start with a definition. The thyroid gland is an important organ that regulates metabolism. It is located in the front of the neck just below the voicebox (larynx).
