Saint Bernard Health Guide: Hereditary Issues & Testing

The Saint Bernard dog is an impressive giant breed originally from the Swiss Alps, historically famed as a mountain rescue dog. Celebrated for their formidable strength paired with a gentle temperament, male Saint Bernards in the US typically stand between 28 to 30 inches tall and weigh from 140 to 180 pounds, with females generally slightly smaller. Their coat varies from smooth to rough, usually displaying rich red or mahogany tones accented by stark white patches and sometimes black markings on the face. Despite their large frame, Saint Bernards are calm and affectionate family pets, known for being especially patient and dependable around children.

In the United States, Saint Bernards are beloved companions. Anyone thinking about adding this breed to their family should fully understand the breed’s health profile, longevity, and inherited risks. This guide discusses the main hereditary health concerns in Saint Bernards and outlines essential testing to promote responsible ownership and breeding practices specific to the American context.

Saint Bernard Lifespan and Longevity

Saint Bernards typically live around 8 to 10 years, which is typical for giant breeds that often face more health challenges due to their size. Knowing this helps pet owners set realistic expectations and tailor care plans to maximize quality of life for their dogs.

Genetic Diversity and Inbreeding Considerations

Maintaining good genetic diversity is pivotal for healthy purebred dogs. In the US, responsible breeders ensure the coefficient of inbreeding (COI) is kept low to avoid health complications tied to close breeding. Moderate genetic variability helps reduce the incidence of hereditary diseases. Adhering to breed standards and genetic screening protocols is vital, particularly given the breed’s predisposition to several health issues.

Physical Traits and Conformational Health Risks

Due to their size, Saint Bernards are susceptible to joint strain, muscle problems, and cardiac stress. It’s important to shield young dogs from excessive exertion to support healthy joint and bone development. Their deep chests increase susceptibility to bloat, also called gastric dilatation-volvulus (GDV), a potentially fatal condition that requires immediate veterinary intervention. Potential owners should also be prepared for the drooling that is typical of the breed.

Essential Health Screening Tests for Saint Bernards in the USA

Health testing is crucial to identify and limit inherited risks. US veterinary professionals recommend:

• PennHIP Hip Evaluation: This is a key screening to evaluate hip laxity and reduce risks of hip dysplasia. While average scores vary, puppies intended for breeding should exhibit low laxity scores.
• Elbow Dysplasia Screening: Ideal test results show no evidence of elbow dysplasia to confirm joint health.

Saint Bernards are recognized as a breed facing multiple inherited health challenges that can impact lifespan and wellbeing. Continued health monitoring and testing by veterinarians is paramount.

Additional Common Health Concerns

Beyond joint and cardiac issues, the breed can be prone to various inherited and acquired conditions, including:

• Eyelid abnormalities such as entropion and ectropion
• Lip fold infections (pyoderma)
• Callus dermatitis on pressure points like elbows and knees
• Panosteitis, causing bone inflammation and lameness in juveniles
• Hypothyroidism affecting metabolism
• Cataracts, which are usually treatable to preserve sight
• Pyometra, a serious uterine infection in unspayed females
• Various ocular issues potentially impairing vision
• Blood clotting disorders including hemophilia
• Heart diseases like dilated cardiomyopathy leading to heart failure
• Cruciate ligament injuries affecting joint stability
• Several cancers such as osteosarcoma and other neoplasias
• Idiopathic epilepsy causing seizures
• Osteochondrosis of the shoulder leading to chronic pain
• Uveodermatologic syndrome, a rare autoimmune disorder causing tissue damage and blindness

Benefits of Genetic Testing and Phenotypic Screening

Genetic testing is increasingly accessible for Saint Bernards. Specific tests target conditions such as laryngeal paralysis-polyneuropathy (LPPN). Breeders can use these results to avoid transmitting these diseases and gradually reduce their prevalence.

Phenotypic screening involves physical examination, X-rays, and specialist veterinary assessments, which are especially effective for detecting structural problems like hip and elbow dysplasia before clinical signs become apparent.

Encouraging Responsible Ownership and Breeding Practices

Being a responsible Saint Bernard owner means understanding the breed’s unique requirements, including providing gentle, appropriate exercise for joint health, keenly observing any health changes, and scheduling regular check-ups with a trusted veterinarian. Prospective owners should seek puppies from reputable breeders who perform recommended health testing, socialize puppies early, and support owners throughout the dog’s life.

Supporting ethical breeding and well-informed care helps ensure that Saint Bernards continue to thrive as gentle giants and valued family members in American homes.
