The Rottweiler Saint Bernard mix is the combination of a Saint Bernard and a Rottweiler. They are adaptive, calm, intelligent, and gentle dogs. While they are quiet animals, they need exercise and regular check-ups. Saint Bernard Rottweiler mixes are perfect for future owners with big play areas.

Rottweilers and Saint Bernards, the parent breeds of this mix, both have distinctive looks. They’re well-known for their size, jowls, and coats and both parent breeds need to maintain their fitness to lessen their risk of health injuries. 

The offspring, Rottweiler Saint Bernard mixes, inherit good as well as bad characteristics from their parents. But what exactly do they look like? And are they good with kids or are they aggressive?

In this article, we will talk about the Rottweiler Saint Bernard mixes’ temperament, origins, food requirements, exercise needs, grooming requirements, and more. 

Rottweiler Saint Bernard Mix Characteristics

The Rottweiler Saint Bernard mix has unique characteristics. They can either look like a Rottweiler, a Saint Bernard, or a combination of both breeds. Their personality depends on their upbringing and which parent’s genes are more dominant.

The International Designer Canine Registry (IDCR) recognizes the Rottweiler Saint Bernard mix for its remarkable characteristics, resulting from combining the two parent breeds – Rottweilers and Saint Bernards[1].

Rottweilers are protective, quiet, wise dogs that are great with kids, while Saint Bernards are affectionate, calm, and intelligent dogs known as “gentle giants”.

Although they have similar traits, they also have opposite characteristics. Rottweilers are vigilant against strangers while Saint Bernards welcome them with open arms.

3 Pros of Having a Saint Bernard Rottweiler Mix

The Saint Bernard Rottweiler mix is a calm dog that is great with kids and can adjust to any climate.

1. They Are Great With Kids

Given St. Bernards’ affectionate nature, Rottweiler Saint Bernard mixes are great with kids. They love to bond with children. St. Weilers (the nickname of Rottweiler Saint Bernard mixes) are great playmates for your children due to Rottweilers’ playful traits.   

Rottweiler Saint Bernard mixes are also protective. Although gentle and calm dogs, they are vigilant against unfamiliar people and animals. Rottweiler Saint Bernard mixes do not hesitate in taking action, mainly through barking, against anyone that’s not familiar. 

Their vigilant trait assures that someone is looking out for your children when you’re not. They also make excellent guard dogs for your home or property. 

2. Saint Bernard Rottweiler Mixes Are Calm Dogs

They have a calm demeanor. This mixed breed is only energetic when someone is playing with them. They spend most of their time lying down or sleeping, like Saint Bernards. 

Both parent breeds originally worked as drovers and protectors for farmers. They developed a calm and self-controlled nature to become efficient workers. Saint Bernard Rottweiler mixes inherit their parents’ calm nature. They are also excellent herders and guardians. 

Given their calm nature, Rottweiler St. Bernard mixes are quiet animals. They only bark when they see someone that’s not familiar with them. 

3. They Can Adapt to Any Climate

Rottweiler St. Bernard mixes can adapt to any climate. They get their tolerance for heat and cold from their parents. Rottweilers thrive in warm temperatures, while Saint Bernards live in cold environments.

They, like Rottweilers and Saint Bernards, are double-coated dogs. The American Kennel Council (AKC) mentions that the coats of double-coated dogs serve as insulators[2]. In cold climates, their coats keep them warm, while their coats help regulate heat in hot climates.

3 Cons Of Having A Saint Bernard Rottweiler Mix

Saint Bernard Rottweiler mixes are heavy droolers that shed their coats frequently and are prone to hip dysplasia. 

1. Rottweiler St. Bernard Mixes Are Heavy Droolers

Both Rottweilers and Saint Bernards are known for their prominent jowls that result in heavy drooling. Saliva that accumulates in the skin folds of their jowls causes heavy drooling. Rottweiler Saint Bernard mixes inherit their parents’ unwanted traits. 

It is not exactly a bad thing since it is normal, but prospective owners might be upset with their Rottweiler Saint Bernard mix because it leaves drool all over their house. 

2. They Are Prone to Hip Dysplasia 

Rottweilers and Saint Bernards carry the hip dysplasia-causing gene. Hip dysplasia is a condition where a dog’s femur or thigh bone does not fit with their hip socket[3] which results in leg deformity and walking difficulties. 

Their offspring, the Rottweiler Saint Bernard mix, inherits the hip dysplasia-causing gene from its parents. Its large build also contributes to its risk of hip dysplasia. 

Rottweiler Saint Bernard mixes are prone not only to hip dysplasia but to numerous health conditions, such as heart, eye, and bone-related issues. 

3. They Shed A Lot

Both Rottweilers and Saint Bernards are frequent shedders. They do this to remove old and damaged hair in their coat. Like their parents, Rottweiler Saint Bernard mixes shed heavily. They require regular grooming because of this.

Shed hair can increase allergens in the air. It can also stick to clothes and pieces of furniture, which can be difficult to clean. 

Rottweiler Saint Bernard Mix Origins

There is little information about where the Saint Bernard Corgi mix originated; however, they likely came from the Central European region because both parent breeds originated in that area.

Saint Bernards originated in Switzerland. They evolved from an ancient dog breed called Molosser. Romans brought Molossers when they invaded the Swiss region during the 2nd century BC. Molossers then interacted with the native dogs in the area. Their combination produced the Saint Bernard Breed. 

Their name came from the Great St. Bernard Hospice found in the treacherous Great St. Bernard pass. The hospice used Saint Bernards as rescue workers[4]. This large dog also served people as herders and guardians.

Rottweilers originally came from Rottweil, Germany. Their breed also evolved from Molossers. Romans bred Molossers with other breeds to produce drover dogs, such as Italian Mastiffs and Asian Mastiffs. When the Roman Empire crumbled, villagers used these dogs for agriculture, safety, communication, etc. Rottweilers get their name from the Rottweil village, where their ancestors worked as cattle dogs[5].

The Rottweiler Saint Bernard mix likely came from Central Europe based on their parents’ origins because both Rottweilers and Saint Bernards originated in Central Europe. 

Saint Bernard Rottweiler Mix Appearance

A typical Rottweiler Saint Bernard mix has a large build that combines the look of a Rottweiler and a Saint Bernard. They have floppy ears, dark brown eyes, prominent jowls, and a tan-colored coat. There are times when they look like either a Rottweiler or a Saint Bernard, depending on which parent’s genes are more dominant. 

Rottweilers have dark coats, tan-colored patches in their limbs, and massive builds, while Saint Bernards have loose jowls, brown and white patched coats, and huge figures. 

If the offspring of this Rottweiler mix takes after their Rottweiler parent, a Saint Bernard Rottweiler mix will have a dark coat with tan-colored patches in their belly and lower limbs. A Rottweiler Saint Bernard mix that takes after its Saint Bernard parent will have a white-colored coat with brown patches all over their body.

Grooming Your Saint Bernard Rottweiler Mix
