Pug Dog Hereditary Health: Essential Testing Guide

The pug is a beloved companion dog in the UK, recognised for its charming personality and distinctive appearance characterised by a compact body, curled tail, and iconic squashed face. While their affectionate nature makes them wonderful pets, the breed’s unique physical traits result from selective breeding that has inadvertently contributed to several hereditary health conditions.

If you are considering bringing home a pug puppy, it is essential to understand these health nuances to ensure your future pet’s wellbeing and longevity. This comprehensive guide covers the most common hereditary health issues and the recommended testing breeders undertake to uphold breed health in the UK.

Understanding Pug Longevity and Genetic Diversity

The average lifespan of a pug is approximately 11 years, slightly shorter than many breeds of similar size. This reduced longevity is influenced by several genetic illnesses prevalent within the breed. Despite a coefficient of inbreeding of 5.7%, which is below the general pedigree norm of 6.25%, the breed's limited diversity within UK lines means that some pedigrees carry much higher inbreeding, increasing hereditary risks.

Common Health Concerns Due to Pug Conformation

Selective breeding has amplified certain physical traits in pugs that can affect their health and comfort:

• Brachycephalic syndrome resulting from their flat faces leads to breathing difficulties, snoring, and heat intolerance.
• Facial skin folds require dedicated cleaning to prevent infection due to trapped debris and bacteria.
• Curled tail deformities (hemivertebrae) risk spinal complications, including paralysis if more widespread.
• Distinct facial structure may impair communication with other dogs, which can influence behaviour and socialisation.

Key Hereditary Health Tests for Pugs

The Kennel Club identifies the pug as a "high profile" breed, encouraging rigorous health testing standards to mitigate hereditary diseases. Responsible breeders adhere to the following testing protocols:

• Hip Dysplasia Screening: With an average breed hip score of 24.9, pugs show a susceptibility to hip joint issues, assessed via radiographic hip scoring.
• Pug Dog Encephalitis (PDE) DNA Test: This fatal inflammatory brain disease causes seizures and is rapidly progressive. Genetic testing helps identify carriers, allowing breeders to make informed mating decisions.
• Degenerative Myelopathy DNA Testing: This spinal cord disorder can cause paralysis; DNA tests identify risk carriers.
• Hemivertebrae Screening: X-rays of breeding adults help detect this spinal deformity, though asymptomatic carriers may still pass genes on.

Other Health Risks in Pugs

Additional concerns that pug owners should be aware of include:

• Hypothyroidism, an underactive thyroid affecting metabolism.
• Legg-Calve-Perthes disease impacting the femoral head, leading to lameness.
• Type 1 diabetes, requiring veterinary management.
• Eye conditions such as distichiasis (extra eyelashes), dry eye (keratoconjunctivitis sicca), and pigmentary keratitis which can impair vision.
• Risks of complicated births often necessitating caesarean sections.
• Cancer types including mast cell tumours and histiocytoma.
• Intervertebral disc disease and tracheal collapse impacting mobility and respiratory function.
• Skin fold dermatitis and atopy, allergic reactions to environmental particles.
• Patellar luxation and epilepsy affecting joint function and neurological health respectively.

Choosing a Responsible Pug Breeder

When looking to adopt or buy a pug, prioritise breeders who conduct comprehensive health testing and openly share results. A reputable Pug breeder will also support puppy owners with ongoing health advice and promote ethical breeding practices to improve the breed's overall wellbeing.

Responsible breeding combines genetic screening, careful match selection, environmental care, and proper nutrition to enhance the health and lifespan of pugs. This approach conserves precious breed qualities while mitigating hereditary risks.

Summary and Next Steps for Pug Owners

Understanding the hereditary health challenges and testing protocols associated with pugs allows prospective and current owners to make informed decisions for their pets' care. An 11-year average lifespan can be supported by preventive health screenings, vigilant grooming, exercise tailored to their respiratory capacity, and regular vet check-ups.

By choosing a pug puppy from a responsible breeder who adheres to recommended health testing for Pug Dog Encephalitis, hip dysplasia, patellar luxation, and spinal deformities, owners can enjoy the companionship of a healthier, happier pug for years to come.
