Dog Canine Hypothyroidism Screening

Thyroid screening in predisposed breeds allows early detection of hypothyroidism before clinical signs cause significant welfare compromise.

Key Facts

Thyroid hormone screening panels detect subclinical hypothyroidism before overt clinical signs develop
Breeding stock screening reduces heritability of autoimmune thyroiditis in predisposed breeds
Annual thyroid checks in senior Dobermans, Golden Retrievers, and similar breeds are recommended
Once diagnosed, treatment costs are low and clinical response is excellent
Autoimmune thyroiditis detected young allows breeding decisions that reduce disease in future generations

Welfare Considerations

Catching hypothyroidism before significant weight gain, lethargy, and skin changes occur prevents prolonged unrecognized suffering. Breeding screening reduces the number of future dogs affected.

What You Can Do

Screen breeds predisposed to hypothyroidism from age 4 to 5 annually
Request thyroid antibody testing as part of breeding health screening
Support breed clubs that advocate for mandatory thyroid health testing before breeding
