Canine Hypothyroidism

Diagnosing and Treating Underactive Thyroid Problems in Dogs


Updated December 03, 2003

by Mary J. Shomon

Hypothyroidism is a disorder of the thyroid gland. This gland has a number of functions, but is most well known for regulating your dog’s metabolic rate. Hypothyroid dogs who receive proper treatment have a normal life span and are able to maintain good health well into their golden years.

While there is a genetic predisposition for thyroid disorders, environmental factors such as pollutants and allergies probably play a role as well. What every dog owner needs to know is:
  • What is hypothyroidism
  • How does a dog get hypothyroidism
  • What are the symptoms?
  • Are certain breeds more susceptible?
  • Is age or gender a factor
  • How is it diagnosed?
  • How is it treated?
  • What should I expect?
More detailed information on canine hypothyroidism is featured in an online Frequently Asked Questions on Canine Hypothyroidism guide.
