Old English Sheepdog Health: Hereditary Issues & Testing

The Old English Sheepdog puppies are instantly recognizable, often dubbed “The Dulux dog” from popular paint commercials in the U.S. This large herding breed, developed with roots in the UK, boasts a long, dense double coat that is water-resistant but demands substantial daily grooming to prevent matting and maintain overall comfort and health. Puppies typically start out black and white and gradually develop their mature coat color with age.

Adult Old English Sheepdogs stand as tall as 24 inches and can weigh up to 100 pounds, with males generally being larger. Known for their gentle rolling gait and calm temperament, they make affectionate companions.

If you’re thinking of welcoming one into your home, it’s crucial to understand the hereditary health challenges associated with the breed and the recommended health screenings aimed at protecting your dog and promoting breed health.

Average Lifespan & Genetic Considerations

Old English Sheepdogs usually live around 10 to 12 years in the United States, a typical lifespan for large breeds. This is somewhat shorter than some medium-sized breeds, underscoring the need for awareness of potential health issues. The breed has historically faced genetic diversity challenges, with concerns about inbreeding that can elevate risks for inherited diseases. Ethical breeders in the U.S. work diligently to minimize these risks by maintaining genetic diversity and carefully selecting breeding pairs.

Common Hereditary Health Conditions

Several inherited health problems can affect Old English Sheepdogs, potentially impacting their quality of life if not managed properly. These include:

• Hip Dysplasia: A common inherited joint disorder in large dogs that leads to arthritis and mobility difficulties. Breeders typically screen with Orthopedic Foundation for Animals (OFA) or PennHIP tests to prevent affected dogs from breeding.
• Multiocular Defect (MOD): A genetic eye disorder caused by a mutation in the COL11A1 gene, affecting various eye structures and possibly leading to vision impairment.
• Cerebellar Abiotrophy (Hereditary Ataxia): This neurological condition results in loss of coordination and balance due to cerebellar cell degeneration.
• Congenital Deafness: Often linked to genes that influence coat color, such as piebald or merle, and may affect one or both ears. Deaf dogs require special care and are usually excluded from breeding programs.
• Cataracts and Progressive Retinal Atrophy (PRA): These eye diseases typically impact older dogs and can result in vision loss, though some cases are treatable with surgery.
• Portosystemic Shunt: A condition where blood bypasses the liver, allowing toxins to accumulate in the bloodstream.
• Immune-Mediated Disorders: Including hemolytic anemia affecting red blood cells and uveodermatologic syndrome, which may lead to blindness.
• Entropion and Distichiasis: Eyelid and eyelash abnormalities causing eye irritation and discomfort.
• Other Noteworthy Conditions: Osteochondrosis of the shoulder (particularly in males), urinary incontinence in early-spayed females, bladder stones, and various cancers in older dogs are also documented concerns.

Health Testing and Ethical Breeding Practices

Leading U.S. breed organizations such as the Old English Sheepdog Club of America (OESCA) and veterinary groups stress the importance of pre-breeding health screenings. Recommended tests include:

• Hip and Elbow Dysplasia Screening: Performed via OFA or PennHIP to identify dogs with joint abnormalities.
• Annual Eye Exams: Through organizations like the Canine Eye Registration Foundation (CERF) to detect congenital and hereditary eye diseases, including PRA and MOD.
• Thyroid Function Tests: To check for hypothyroidism, which is common in the breed.
• Cardiac Evaluations: To rule out heart-related issues.
• Hearing Tests: Using BAER (Brainstem Auditory Evoked Response) testing for congenital deafness.
• DNA Screenings: For specific genetic markers like cerebellar degeneration and multi-drug resistance (MDR1) when available.

Responsible breeders will provide health clearances for both parents to reduce the incidence of passing hereditary diseases. Prospective owners should seek puppies from such reputable breeders who specifically follow these health protocols.

Grooming Tips and Care Guidelines for American Owners

The Old English Sheepdog’s thick, shaggy coat requires a significant grooming commitment to stay in good condition. Owners in the U.S. typically spend at least 3 to 4 hours per week brushing to prevent mats and tangles, utilizing slicker brushes, combs, and grooming scissors. Seasonal shedding demands increased attention, particularly in spring and fall.

Bathing should be regular but not excessive to avoid stripping essential natural oils from the coat. Many American owners opt for periodic visits to professional groomers who are experienced with this breed's unique needs. Additionally, trimming or tying back the hair around the eyes helps maintain clear vision and prevents irritation, which supports skin health and reduces risks of infections common in dense coats.

Owners moving to the U.S. from other regions should be mindful that shedding is inevitable, and adjusting to this reality is part of responsible ownership.

Conclusion: Advocating for Health and Longevity in Old English Sheepdogs

The Old English Sheepdog is a lovable and calm breed that thrives under knowledgeable and attentive care. Staying informed about hereditary health risks and supporting responsible breeding practices through comprehensive health testing can enhance the wellbeing and lifespan of these dogs. Regular visits to the veterinarian, combined with diligent grooming, are vital to maintaining their quality of life. If you're looking to add an Old English Sheepdog puppy to your family, prioritize breeders with a proven commitment to health screening and breed preservation to ensure you welcome a joyful, long-lived companion into your home.
