Irish Wolfhound Health Testing Requirements for Stud Dogs

Irish Wolfhounds are the world's tallest dog breed — and tragically, one of the shortest-lived. Average lifespan is 6-8 years, driven largely by dilated cardiomyopathy, bone cancer, and other giant-breed health burdens.

The Irish Wolfhound Club of America (IWCA) participates in the OFA CHIC program and maintains an active health committee.

CHIC Requirements for Irish Wolfhounds

• OFA Cardiac Evaluation (echocardiogram)
• OFA Hip Evaluation
• OFA Elbow Evaluation
• OFA Eye Examination (CAER)
• DNA test for Degenerative Myelopathy (DM/SOD1)

Dilated Cardiomyopathy (DCM)

DCM is the most common cause of death in Irish Wolfhounds. Prevalence exceeds 30% of the breed. Annual echocardiogram is required for all breeding dogs. Dogs with DCM should not be bred. Dogs whose parents developed DCM before age 5 should be evaluated with particular care.

Osteosarcoma (Bone Cancer)

Irish Wolfhounds have a high lifetime bone cancer risk. No genetic test exists. Pedigree longevity data is the most relevant signal — ask breeders specifically about cancer history and causes of death in parents and grandparents.

Hepatic Portosystemic Shunts

Liver shunts occur in Irish Wolfhounds at higher rates than most breeds. No DNA test; select against pedigrees with liver shunt history.

Bloat/GDV

As the tallest breed, Irish Wolfhounds have significant GDV risk. Prophylactic gastropexy is widely recommended by veterinarians familiar with the breed.

Hip and Elbow Evaluation

OFA evaluation for hips and elbows; both conditions occur in this breed.

Summary

A responsible Irish Wolfhound stud dog must have: annual echocardiogram (clear), OFA hip and elbow evaluations, OFA CAER eye exam, and DM DNA testing. Cardiac screening by echocardiogram — not just auscultation — is essential. Longevity data in the pedigree (parents and grandparents living to 8+ years) is one of the most meaningful breeding selection criteria available for this short-lived breed.
