Hypothyroidism is a disorder of the thyroid gland. This gland has a number of functions, but is most well known for regulating your dogs 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:

- Are certain breeds more susceptible?
- Is age or gender a factor
- How is it diagnosed?
- How is it treated?
