There has been some confusion about the OFA heart testing requirements for Irish Wolfhounds. To clarify: a Holter monitor screening is NOT required for IWs. The OFA website clearly states that it is only required for Boxers and Dobermans, but some forms apparently say it is required for other breeds, including IWs. The forms are incorrect. Please refer your cardiologist to the OFA website if necessary to verify that it is not required.
The tests that are required by the OFA for Irish Wolfhounds are: auscultation, EKG and echocardiogram performed by a Board-certified veterinary cardiologist.
