Congenital Hypothyroidism with Goiter in Dogs: Causes & Care

The Spanish Water Dog and several other breeds in the United States can be affected by congenital hypothyroidism with goiter (CHG), a significant inherited disorder that impacts thyroid hormone production. Without treatment, CHG is often fatal in puppies; however, early detection and management can greatly improve survival and quality of life. Responsible breeders in the U.S. typically perform genetic carrier screening to decrease the chance of passing this condition on to future generations.
