Kerry Blue Terrier Health & Lifespan: Hereditary Issues Explained

The Kerry Blue Terrier, also known as the Irish Blue Terrier, was originally bred as a working dog to control vermin such as rats and rabbits. Over time, it has taken on roles as a herding and farm guard dog. Today, while primarily kept as a companion pet, this breed's popularity in the UK has declined over the past three decades, though it remains a robust and distinctive breed.

This terrier is noted for its deep chest, long head, and soft, fine coat that ranges from wavy to curly. Born entirely black, Kerry Blue puppies develop the breed's characteristic blue-grey coat as they mature. The coat texture is more akin to human hair than typical dog fur, lacking an undercoat and shedding minimally. Regular grooming and brushing are essential to maintain coat health.

Adult Kerry Blue Terriers typically stand up to 19 inches tall at the withers and weigh up to 15kg, with males generally larger than females. Prospective owners should conduct thorough research to ensure the breed fits their lifestyle and expectations.

Average Lifespan of the Kerry Blue Terrier

The average life expectancy of a Kerry Blue Terrier ranges from 12 to 15 years, which is notably longer than many breeds of similar size. This impressive longevity suggests a naturally hardy breed with relatively few chronic health issues when responsibly bred and well cared for.

Genetic Diversity and Breeding Recommendations

The breed shows a coefficient of inbreeding (COI) of approximately 13.2%, exceeding the recommended level of 6.25% or less ideal for pedigree dogs. This higher COI reflects the smaller gene pool due to fewer registered dogs. Responsible breeders are encouraged to minimise inbreeding to maintain genetic diversity and reduce inherited health issues.

Conformation and Maintenance

Kerry Blues have a balanced and healthy body structure with few breed-specific physical limitations. However, their ears often develop an excess of hair, which requires regular trimming to prevent wax buildup, infections, or hearing impairment. The long facial hair can obscure their eyes, necessitating routine grooming for clear vision and comfort.

Key Health Tests for Responsible Breeders

Hereditary conditions known in some Kerry Blue lines require pre-breeding health screening to ensure healthy offspring. Recommended tests include:

• Hip scoring for hip dysplasia, aiming for a score below the breed mean of 15.
• Elbow dysplasia testing, seeking an ideal elbow score of zero.
• DNA tests for blood clotting disorders such as Von Willebrand’s disease and Factor XI deficiency (haemophilia).
• Screening for degenerative myelopathy, a progressive spinal condition causing hind limb paralysis.

Other Potential Health Concerns

Besides the main hereditary issues, Kerry Blues may have elevated risks for other conditions, including:

• Cataracts affecting vision.
• Entropion, where eyelids roll inward causing irritation and discomfort, sometimes requiring surgery.
• Dry eye (Keratoconjunctivitis Sicca), leading to inflammation and potential vision loss.
• Patent ductus arteriosus, a heart defect impacting blood circulation.
• Skin issues such as sebaceous cysts.
• Basal and squamous cell carcinomas (types of skin cancer).
• Progressive neuronal abiotrophy, a rare fatal neurological disorder manifesting in young puppies with symptoms like tremors and weakness.
• Hypothyroidism, causing lethargy and weight gain due to an underactive thyroid gland.

Promoting Healthy Kerry Blue Terriers

Choosing a reputable Kerry Blue Terrier breeder who rigorously tests for genetic conditions is crucial. Prospective owners should prioritize health-clearance certifications when finding a puppy. Regular vet check-ups, proper diet, exercise, and grooming will support a Kerry Blue’s well-being and longevity.

Ongoing research and breed health initiatives aim to reduce inherited health risks through better genetic understanding and responsible breeding practices.

When Can Puppies Leave Their Mother?

Quick Answer: Kerry Blue Terrier puppies should ideally stay with their mother until at least 8 weeks old, allowing vital social and health development.

Puppies benefit greatly from their mother's care and littermates for emotional growth, socialisation, and immune support through milk. Early separation can affect behaviour and health negatively. Responsible breeders ensure puppies are weaned correctly and receive initial vaccinations before going to their new homes.

Questions to Ask When Buying a Kerry Blue Terrier Puppy

To make a well-informed decision when looking for a Kerry Blue Terrier puppy, consider asking breeders these important questions:

• Can you provide health screening results for the puppy’s parents?
• Do you perform tests for hip and elbow dysplasia?
• Have the parents been screened for blood clotting disorders like Von Willebrand’s disease?
• Is there any history of neurological conditions such as degenerative myelopathy in the lineage?
• What socialisation and early training do puppies receive?

These inquiries help ensure you are acquiring a puppy raised with attention to health and welfare.

Conclusion

The Kerry Blue Terrier is a charming, hardy breed known for its unique coat and vigorous nature. With an average lifespan of 12–15 years, they often enjoy long, healthy lives when bred responsibly. Awareness of hereditary health predispositions and adherence to recommended health screening by breeders safeguard the breed’s future and help owners enjoy many happy years with their Kerry Blue companion.
