St Weiler
The St Weiler is a cross between the Rottweiler and the Saint Bernard. Because each hybrid inherits a unique combination of traits from both parents, we recommend thoroughly researching both breeds before choosing a St Weiler. Pay special attention to temperament, health issues, and care requirements, as your dog may express characteristics from either parent breed.
Rottweiler
The Rottweiler is a powerful, well-muscled dog that presents an image of great strength and endurance while maintaining a noble, confident demeanor. Males typically stand 24 to 27 inches at the shoulder and weigh 95 to 135 pounds, while females measure 22 to 25 inches and weigh 80 to 100 pounds. The breed possesses a compact, substantial body that is slightly longer than tall, demonstrating balanced proportions that combine power with agility and athletic capability. Their broad, deep chest and well-developed musculature reflect the breed's heritage as a working dog capable of demanding physical tasks including herding livestock, pulling carts, and serving as a guardian. The Rottweiler's head is one of its most distinctive features, presenting a broad skull of medium length with a well-defined stop and powerful jaws capable of impressive bite force. The muzzle is strong and square, approximately equal in length to the skull, with tight-fitting lips that may cause some drooling in dogs with looser flews. The medium-sized, almond-shaped eyes are dark brown and convey an alert, confident expression that reflects the breed's intelligent and watchful nature. Triangular ears are set high on the head and hang forward close to the cheeks, framing the face and contributing to the breed's attentive appearance. The coat is straight, dense, and of medium length, lying flat against the body with a soft undercoat present on the neck and thighs that provides insulation in colder weather. Rottweilers display the distinctive black-and-tan coloration, with a solid black base color and clearly defined rust to mahogany markings on the cheeks, muzzle, chest, legs, and above the eyes. These markings follow a specific pattern that gives each dog its characteristic appearance immediately recognizable to breed enthusiasts. The tail traditionally was docked short in some countries, though many dogs now retain their natural long tails.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament Rottweilers display natural guarding instincts and remain alert to their environment, making them excellent watchdogs who assess situations carefully before reacting. They tend to be reserved with strangers initially, warming up once properly introduced. This breed requires substantial mental stimulation and physical exercise to remain well-balanced, as bored or under-exercised Rottweilers may develop destructive behaviors. They generally coexist well with other household pets when raised together, though proper introductions and supervision are important. The breed is not recommended for first-time dog owners due to their size, strength, and need for experienced handling.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Cranial cruciate ligament injuries occur three to seven times more frequently in Rottweilers than in other breeds, causing knee instability that typically requires surgical correction. Bloat, or gastric dilatation-volvulus, presents a life-threatening emergency in this deep-chested breed when the stomach fills with gas and rotates on its axis. Preventive gastropexy surgery may be recommended for at-risk dogs. Other health concerns include progressive retinal atrophy, von Willebrand's disease affecting blood clotting, and various neurological conditions. Responsible breeders conduct comprehensive genetic testing and health screenings to minimize the transmission of hereditary conditions to offspring.
Saint Bernard
The Saint Bernard is a giant breed known for its massive size, powerful build, and gentle expression that has made it one of the most recognizable dog breeds in the world. Males typically stand 28 to 30 inches at the shoulder and weigh 140 to 180 pounds, while females measure 26 to 28 inches and weigh 120 to 140 pounds. Some individuals exceed these standards significantly, with the breed holding records for largest dogs by weight in canine history. The body is powerful and well-proportioned, nearly square in outline with the length approximately equal to the height at the withers. Their substantial bone structure and well-developed musculature reflect the breed's heritage as a working rescue dog in the treacherous Swiss Alps. Two coat varieties exist within the breed: the shorthaired and the longhaired, both developed to withstand harsh alpine conditions. The shorthaired variety features a dense, smooth coat lying flat against the body providing excellent weather protection, while the longhaired variety displays medium-length hair that may be slightly wavy with feathering on the legs and a bushy tail. Both varieties possess a thick undercoat that provides insulation against cold weather conditions. Coat colors are primarily white with red, mahogany, or brindle markings, though the specific pattern varies considerably between individuals creating unique appearances. The face typically features a dark mask around the eyes and dark coloring on the ears. The Saint Bernard's head is massive and imposing, with a broad skull, pronounced stop, and short, square muzzle that conveys both power and gentleness. Deep-set eyes convey a kindly, intelligent expression despite their somewhat droopy appearance that adds character to the face. The medium-sized ears are set high and hang close to the cheeks, adding to the breed's gentle appearance. Distinctive facial features include wrinkled skin on the forehead and jowls that contribute to the breed's characteristic drooling.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament Despite their history as rescue dogs, modern Saint Bernards are relatively low-energy dogs that require only moderate exercise. They prefer cooler climates and do not tolerate heat well due to their thick coats and massive bodies. Air-conditioned living quarters are essential in warm climates. Saints typically display friendly, welcoming behavior toward strangers after proper introduction, though their size alone provides an effective deterrent to unwanted visitors. They generally coexist peacefully with other household pets when properly socialized. The breed's drooling habit and tendency to track mud indoors require owners who can tolerate some messiness in their home.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Osteosarcoma, an aggressive bone cancer, shows hereditary predisposition in the breed and typically affects the limbs. Eye disorders including entropion, where the eyelid rolls inward causing corneal irritation, and ectropion, where the eyelid droops outward exposing the eye, occur frequently due to the breed's loose facial skin. Wobbler syndrome, a neurological condition affecting the cervical spine, causes coordination problems and weakness. Additional concerns include epilepsy, various skin conditions, and laryngeal paralysis. Responsible breeders conduct comprehensive health testing to reduce the transmission of hereditary conditions.
Important to Remember
Each hybrid dog is unique and may inherit any combination of traits from either parent breed. The information above represents the characteristics of the purebred parent breeds. Your St Weiler may favor one parent over the other or display a blend of both. We strongly encourage you to read the complete breed profiles for both the Rottweiler and Saint Bernard to fully understand the range of possible temperaments, health concerns, and care requirements.
