The Saint Berxer might sound like the name of an exotic purebred dog, but this mixed breed is actually the offspring of the Saint Bernard and the Boxer. This is a large hybrid dog that can weigh up to 120 pounds when full grown. But though their size can be intimidating, their loving nature quickly warms people up to their big hearts and playful spirits.

This St Bernard Boxer Mix are gentle giants that love hanging out with children in the yard all day. They have thick coats, so they’re sensitive in the sun and tend to enjoy lounging in shady spaces when it’s especially hot outside. This mixed breed makes a great guard dog, but owners don’t have to worry about any aggression.

If you’re thinking about owning a Saint Berxer of your own, you should know that this mixed breed tends to drool a lot — so be prepared to clean up after them inside the house. Read on to learn everything else you need to know about this powerful yet affectionate large dog breed.

Saint Berxer Puppies – Before You Get One…


Saint Berxers are active dogs that require plenty of outdoor time. In addition to regular walks, this breed needs room to play outside without being held up by a leash. Apartment living isn’t the best option for this large dog although it is possible if multiple walks and some off-leash time at a park can be enjoyed every single day.

3 Little-Known Facts About Saint Berxers

1. They Don’t Necessarily Like the Snow

Saint Bernards may be well known for effectively traversing the snow, but their Saint Berxer offspring don’t always share the same enthusiasm for snowy places. Their coats aren’t quite as thick and long as their Saint Bernard parent, so they can’t handle extremely cold conditions very well.

2. They Don’t Always Like the Sun

Saint Berxers love spending time outside when the weather is warm and beautiful, but they can overheat when spending long periods of time in direct sunlight. They need a nice tree to lay under or they should have an open opportunity to head indoors when they feel the need.

3. They Sometimes Act Like Little Dogs

This mixed dog breed has its independent side, but it also likes to display i’s gentle side as often as possible. So, owners aren’t usually surprised when their huge Saint Berxer tries to cuddle up in their lap just like a Chihuahua might do.

Temperament & Intelligence of the Saint Berxer 🧠

The Saint Berxer is no angel, but it certainly tries to be. Unlike some other large breed dogs, this mixed breed tends to be more loving and affectionate than it is stubborn and independent. This dog makes it a priority to protect their family members, but they are never aggressive in social situations unless a clear and serious threat has been detected.

This beautiful mixed breed is energetic and wants to play during much of their waking hours. They’ll run, jump, and play with kids but should be supervised during play sessions to minimize the risk of injury. Saint Berxers are intelligent and easy to train, even for first-time dog owners. They like to please their family members and are typically willing to do just about anything for a treat.

With some socialization, the Saint Berxer will warm up to strangers quickly even if they are a little suspect at first. And although Saint Berxers are alert and can effectively work as a watchdog, they don’t like to be left alone for any length of time. Owners should make sure that someone is home to be with them throughout the day or consider hiring a pet sitter or walker a few times a week.

Are These Dogs Good for Families? 🏡

These mixed breed dogs are great with kids and adults alike, but they are not right for every family out there that is looking for a new dog. Families that live in apartments may want to opt for a dog with lower energy levels. Those who don’t have fenced yards to rely on might consider adopting a smaller dog that doesn’t mind spending their days inside instead. But families with kids of all ages, big hearts, houses, fenced yards, and plenty of time for walking and playing would make perfect mates for the Saint Berxer.

Does This Breed Get Along with Other Pets? 🐶 😽

Saint Berxers seem to like other dogs no matter their size, especially if they have been socialized from a young age. These dogs are pretty laid back, so they don’t mind being subjected to new social experiences that involve other dogs. You can expect a Saint Berxer to cuddle up with a cat just as quickly as it would snuggle with one of your children. In short, this breed can get along with a variety of other animals as long as they are properly introduced.

Things to Know When Owning a Saint Berxer:

Saint Berxers are nice looking dogs that are fun to both play and cuddle with, but they require tons of attention, lots of food, and regular visits to the veterinarian’s office to maintain a high quality of life.

Food & Diet Requirements 🦴

Your Saint Berxer could eat three or more cups of food every day depending on things such as how much they weigh, how much exercise they get, and how naturally active they are throughout the day. This mixed breed will eat whatever you put in front of it, so free feeding isn’t a good idea.

These dogs should eat two or three separate meals a day to support their digestive system. Wet or dry dog food should be formulated to support large dog breeds and should be free of unnecessary fillers like corn and soy. Look for foods that contain carrots, peas, spinach, and flaxseed instead.

Exercise 🐕

Due to its active nature and working instinct, the Saint Berxer should be exercised for at least 45 minutes every day. A missed day once in a blue moon due to an illness or a lazy day won’t affect your dog’s happiness or attitude. But miss too many exercise days, and you may find that you’re left with an unruly and destructive dog on hand.

Walking through your neighborhood, hiking in the woods, spending time at a dog park, and playing games like hide-and-seek inside all count toward exercise. Add a couple hours of play in the yard and you’re in for a relaxed, loving dog that is ready to cuddle at the end of the day.

Training 🦮

Luckily, this is a mixed dog breed that is easy to train. If a Saint Berxer does not know how to sit and stay, it could accidentally destroy your belongings while trying to get along in the house thanks to its large stature. So, training should start early and should be done often until the pup can quickly comply with commands regularly.

Agility training will help exercise this breed’s body and mind, but because they’re so big they aren’t usually as fast on the course as other breeds. Saint Berxers will naturally protect their home, so they don’t need any special watchdog training. However, this mixed breed would do well should owners choose to invest time and money in guard training.

Grooming ✂️

This type of dog tends to shed a lot, so brushing or combing a few times a week is necessary to get rid of excess hair to keep the coat looking shiny. Drool can be cleaned off the coat with a damp cloth. But it’s a good idea to avoid full baths if possible, to avoid stripping important oils from the dog’s skin and fur. This mixed breed is active enough to keep its nails nice and short, but they do need a little help when it comes to keeping their ears and teeth clean. Check the ears for debris once a week and brush the dog’s teeth or give them a dental bone on a regular basis.

Health and Conditions ❤️

There are quite a few health concerns the average Saint Berxer might experience during their lifetime. A veterinarian can monitor your dog as they age to catch any possible problems early, so they can be addressed before any serious illnesses develop.

Minor Conditions
  • Von Willebrand’s disease
  • Hypothyroidism
  • Colitis
  • Hip and elbow dysplasia
Serious Conditions
  • Gastric torsion
  • Heart disease
  • Cardiomyopathy
  • Degenerative myelopathy
  • Subvalvular aortic stenosis

Male vs Female

The biggest difference between Saint Berxer genders is their size. Males are typically at least 10 pounds heavier than their female siblings and they can be as much as two or three inches taller. Both boys and gals are gentle and dignified. They love their families and their play time, although boys are a bit more exuberant when left to their own devices. Both males and females are suitable for active families.

Final Thoughts on the Saint Berxer

The ever-mighty Saint Berxer is no saint, but it is a well-behaved breed that is easy to work and live with. Kids should know how to properly handle dogs before being left alone with these dogs. But once well-acquainted, Saint Berxers will spend hours keeping their children family members company. They’re easy to care for, but they require lots of attention so don’t expect to leave them on their own while you work and adventure without them. Overall, if you have the time and the love to give an active large breed dog, you should seriously consider adopting the impressive Saint Berxer.
