Mastiff Boxer Mix Facts

Mastiff Boxer Mix Facts

Aside from enjoying what I do, I love seeing the looks on the owner’s faces whenever they see their pets in a good state, as well as when I treat them. Another priceless moment was when I had the chance to treat almost a hundred dogs (or more) and talk to the owners. With this, I firmly believe that dogs, just as humans do, deserve a family that loves them, a roof above their heads, and friends that keep them company throughout their lives.

Boxer Crossed With Mastiff

The Boxer mixed with Mastiff, known as the “Boxmas”, is a breed that looks frightening at first glance but in reality, they’re loyal and loves belly rubs! One thing most owners note is that the Boxmas is fiercely protective of its owners as well as very courageous and energetic.

The Boxer breed is a medium-sized dog that exudes energetic and playful energy that radiates especially when they’re with their family and friends. They’re tagged as the “Peter Pan” of breeds because they don’t fully mature until the age of three. A Mastiff, on the other hand, is the largest breed of all. But despite the large built, their temperament is one of the calmest because Mastiff comes from the word “mansuetus” which means domesticated.

Having a Mastiff crossed with Boxer genetically enhances your puppy’s muscular built, as well as their loyalty and outstanding guard watching trait. A natural instinct that may show is the reaction to suspicious people because your hybrid will not bite, but most likely push the stranger to the ground.

3 Reasons Why You Shouldn’t Get A Mastiff Mixed With Boxer

Mastiff mixed with boxer

  1. They “choose” their owners. If you don’t train your Boxer Mastiffs to socialize at an early age, they tend to be a one-owner dog over time and this means being shy or defensive against strangers and new dogs.
  2. They drool everywhere. Most Boxmas owners agree that drool is a common denominator for the hybrid as well as the parent breed. Get your wipes and tissues ready.
  3. Tends to be destructive. When left alone, the Boxer Mastiff mix might get bored and decide to gnaw on anything and everything within their reach. Proper training helps eliminate this trait.

3 Reasons Why You Should Get Mastiff Boxers

  1. They’re natural guard dogs. Boxer Mastiffs have a natural inclination to guard and protect their loved ones. This trait saves you time and effort to train them regarding protection, but don’t be too relaxed. Additional guidance will still go a long way.
  2. The temperament is calm. There’s no need to worry about leaving the kids with your hybrid because both parent breeds, especially the Mastiff, has an even overall temperament. Aggression levels are low to none if appropriately raised.
  3. Their built is intimidating. Coming from a medium and large sized pair of breeds, the Mastiff Boxers turn out quite big and muscular, which deems them as intimidating and scary, especially for strangers. Their muscle built automatically sends off a warning sign without having to do anything.

The Mastiff Boxer mix is a gentle giant that is popular among households because of the great built and even temperament. More families are choosing to adopt a hybrid of the Boxer and Mastiff because of the positive reputation of being very protective and being right around children.

Although they are naturally inclined to be protective, it is best to start early socialization training because if not, your pups will eventually be wary of everyone else aside from your family. While this is a good thing in terms of protection, but it might be a pain to always have to control your hybrid because of socialization issues.

Just as any dog, you Boxer mixed with Mastiff should not be left alone because this makes them restless and agitated which results to them chewing on things big and small. If you turn a blind eye and let this habit go on, your hybrid might uncontrollably destroy more stuff in the future.

Mastiff Crossed With Boxer Puppies For Sale

Families all over the world have started to decide and adopt Boxer Mastiffs because of the built plus calm temperament. This combo is a perfect result of two great parent breeds historically recognized in Europe.

A common misconception is that mixed breeds are healthier than pure breeds, but that’s not always the case. In a research conducted by scientists at UC Davis, they proved that the health of a puppy (hybrid or pure) depends on the health history of both parents as well as the living conditions, etc.

When given a chance to purchase online or pet store, don’t do it. Both are from puppy mills which are involved in breeding, but they don’t necessarily make the health of the parent dogs a priority. These companies or institutions focus too much on the reproduction that they neglect everything — all for transactions and sales.

If you wish to purchase a well fed and well brought up hybrid, opt to contact a local breeder instead. A local breeder is ten times better because unlike online ads or pet stores, they care and love for the puppies they produce. You can even ask for the health history of both parent breeds as well as each puppy, and they’d be happy to present the documents you need. Take note of how they handle and interact with the puppies.

In line with finding a good breeder, make sure you ask to visit the kennel and check the area and space they have for producing hybrids. It is vital to take note of the living conditions they have at home because this may also contribute to the health status of your desired puppy.

Grooming Your Mastiff Mixed With Boxer

Boxer Mastiffs are easy to groom overall but generally shed in large amounts, which is why you should schedule days that you thoroughly brush their fur. Daily brushing is essential even for your short hair because it eliminates and lessens dirt accumulation as well as hair accumulation in the house.

Make sure to eliminate any “doggy smell” by bathing your hybrid but don’t overdo it because it may cause dryness and overproduction of oils. Don’t forget to clean their ears and brush their teeth as well.

Ear and teeth hygiene should be an everyday priority to avoid dirt and bacterial accumulation in the ears and cavities or tartar, which could lead to infections in the future. Chewables are okay, but they don’t entirely replace the purpose of brushing.

Boxer Crossed With Mastiff Health Problems

Boxer crossed with mastiff

A hybrid will generally manifest all good traits from the parent breeds, but it doesn’t mean there are no health concerns you should take note of and check. Some of the conditions to take note of are:

  • Hip Dysplasia: This is a genetic disease wherein there is an abnormal formation of the hip socket, which causes immense pain for the dog. If left untreated may cause crippling and painful arthritis of the joints.
  • Gastric Torsion: Also known as Gastric Dilatation-Volvulus or Gastric Dilation. Due to excessive gastric content, the stomach of the dog becomes overstretched. It may cause severe pain when moving.
  • Ectropion: This condition is more common in Mastiffs. The lower eyelids appear droopy due to an abnormality and may result in conjunctivitis or keratitis.

Always make sure to visit the vet even when your boxer mastiff mix doesn’t show any signs or symptoms to ensure that they are 100% healthy and thriving. Ask for vitamins or supplements that can significantly improve your dog’s health.

Mastiff Crossed With Boxer Food Requirements

Boxer mastiffs

Always prioritize your Boxer Mastiffs food to ensure that they live a long and healthy life. Although large, their lifespan is not as long compared to others, that’s why taking note of what you feed them is essential. If you have the extra time, plan a specific diet according to the breed’s needs.

Your hybrid will grow to be a large dog, so it’s easy to overlook the amount of food you’re going to give. Make sure you make arrangements with members of the family to ensure an adequately measured amount of food for your puppy. Treats are advisable but don’t give them too much. Choose gifts that have low calories instead, so that obesity is avoidable.

The best choice of food would be those that are rich in protein for proper muscle building and repairing. Protein can be obtained through dog food alone, or you could ask your local vet for additional snacks and supplements.

You can find protein in meat such as chicken, lamb, fish, and beef. Meat meals are concentrated forms sans the moisture but offer the same amount of protein as well. Fats are essential for eye and brain development because of the rich sources of Omega-3 Fatty acids. Chicken meat and fish oil are excellent sources.

Avoid giving your Boxmas foods rich in common allergens such as corn, soy, dairy, wheat, and potatoes. Also refrain from giving any food coloring, as these may compromise the immune system. Never give them table food because it might cause different allergic reactions ranging from skin allergies to difficulty in breathing. If continued for a long time, table food can affect your hybrid’s overall health and lead to certain heart diseases.

To give your Boxer crossed with Mastiff better nutrition, check the following high quality and nutrient-packed dog food available on the market:

  • Fromm Large Breed Puppy Gold Formula: This is a brand that ensures there are no allergens or irritants included. Specially formulated for puppies who are known to grow over fifty pounds, protein and fat levels are moderately incorporated. DHA-rich salmon oil is a bonus for brain and eye development.
  • Taste Of The Wild High Prairie Puppy Formula: To ensure your hybrid’s proper growth and muscle development, this brand focuses on the elevation of protein constituents coming from lamb, chicken, and buffalo meals. There are additional vitamins and antioxidants as well as a grain-free formula.
  • Canidae- Life Stages Large Breed Puppy: This formula is for owners who wish to keep their Boxer Mastiffs slim. Protein and fat levels are lower compared to different brands in the market but still packed with needed nutrients and vitamins to ensure proper growth and development.
  • Royal Canin Boxer Adult Dry Food: This product boasts of high-quality proteins and nutrients, as well as the incorporation of L-carnitine. This combination helps your Mastiff mixed with Boxer maintain its overall built, burn fat efficiently, and avoid obesity.
  • Orijen Puppy Large: The ingredients are fresh and high in protein. It consists of chicken and turkey, as well as fish. Ensure your dog’s protein levels with the rich and variable sources this product has to offer.

Your dog may be big or small, but you need to keep it happy and healthy all the time. Never give them the worst dry dog food that is low in nutrients and filled with by-products, and opt for best dry dog food instead. You won’t go wrong if you start with Wellness Core Dog Food, Dog For Dog Food, and Nutra Thrive dog food supplement — they all live up to their amazing reputations.

Boxer Mastiffs Exercise Requirements

Boxer crossed with mastiff

Your hybrid came from two lean and muscular breeds that have a slim built, so it’s best to help them maintain their weight and let them serve their original purpose: to watch, guard, and protect. It’s essential to invest in equipment that enhances your hybrid’s mental capacity as well as the physical aspect.

In line with the diet, also schedule a daily exercise regimen for your Boxmas. They are highly energetic and exuberant by nature, which means they require at least an hour of intense activities and exercises. This program includes running, walking, playing fetch, obedience exercises, and jogging.

Never contain your Boxer crossed with Mastiff in a small space such as apartments or condos. Fulfill their need to stay fit by choosing a home that has adequate running space if you plan to adopt a Boxmas. Another option is to take trips to the park or jog around the neighborhood. All this is for the betterment of your dog’s mental state. If left idle for too long, they can be agitated or easily distracted and tend to destroy or chew on things out of frustration.

Here are some toys to help exercise your Boxmas:

  • OxGord BazooK-9 Tennis Ball Launcher Gun: Since your hybrid is energetic and loves running, this tennis ball launcher is a perfect toy when visiting parks or playing in the backyard. Creators are confident your Boxmas won’t tire quickly with this product because it also hastens their hunting skills when searching for the ball.
  • Planet Dog Orbee-Tuff Cosmos, Luna: What sets this apart from the usual toy ball is that it glows in the dark. In your dog’s alone time, they stimulate their brains during day and night. Invest in this versatile product so that it also saves you energy from having to throw the ball.
  • Nylabone Big Chew Durable Toy Bone For Large Breeds: This is a product that ensures your dog won’t drool all over the place as well as take care of the needed oral hygiene. It prevents the potential risk for periodontal disease.
  • KONG Wubba Dog Toy: Made of nylon and has two balls inside (one chewable and one squeaky), the Wubba dog toy will be a Boxmas favorite because of its durability and appearance.
  • Playology Dual Layer Bone Dog Toy Bacon Scent: This is a good investment because the bacon scent lasts for six months. There is no need to continually throw away and replace toys when you purchase this product. Your hybrid will engage in chewing and decrease any risks of periodontal diseases as well.

Boxer Mixed With Mastiff Training

Mastiff boxers

It’s a no brainer that your Mastiff crossed with Boxer is an intelligent breed, so you have to make a proper plan to execute and train them thoroughly. It can be a challenge for most owners because of the intelligence plus energetic combo, but with patience and determination, your hybrid will follow proper orders in no time.

Boxers are easy to lead and train. This trait will save you a lot of time and effort. On the other hand, Mastiffs are also easy to prepare but take note that they’re capable of play biting.

Make sure to familiarize yourself and your pup with play biting and attacking an intruder or stranger. Training is essential not only for warding off strangers but also for your dog’s proper attitude.

Here are a few tips to help you train your hybrid:

  • Plan many exercises: You should be aware that your Boxer crossed with Mastiff is a very active and energetic breed, so it’s not enough that you impulsively think of possible exercises for the day. If you can, plan for the whole week instead. This strategy will make it easier for you on dull days, and it will be very beneficial for your dog’s mind and body.
  • Train every day: Your hybrid is an intelligent being, which means they’re capable of figuring things out and deciding on their own. It can be a challenge to keep their attention focused on the training, but with perseverance and patience, everything will eventually pay off.
  • Encourage positive reinforcement: Positive reinforcement will always be one of the best and most endorsed strategies to train a dog because it taps into the mental aspect. Your hybrid will automatically think that the specific actions you want your dog to do will earn a treat. Apply this in all tricks and strategies you wish to impart.

Mastiff Boxers And Families

Boxer mixed with mastiff

Before you allow your Boxmas to interact with family members (especially children), ensure that you’ve undergone socialization training to avoid wariness and fear. You may visit the vet and ask for tips on how to improve your hybrid’s social skills, and most likely they’ll advise you to go to the park and let them play with other dogs and let them get used to seeing strangers daily.

Another thing to remember is always to have a big space for them to move around when around children to avoid any unwanted accidents. Your hybrid is a large dog and might be prone to crashes if confined in a small space. You can renovate your backyard and put obstacles or toys, or you may visit the park and play with other dogs.

But in general, Boxer Mastiffs are very loyal, fun, active, and protective. Leaving them along with children is okay, and there’s nothing to worry about or fret. The temperament from both parent breeds ensures that there is no aggressiveness or violence along with, of course, proper training.

Older members of the family can pitch in and help training the big fellow, and this also allows more exposure to different people. This plan will avoid the unwanted one-owner type of dog in the future, as well as agitation and idleness.

As an owner, it is your responsibility to ensure a healthy diet, proper living space, frequent trips to the vet, and specific training to help your hybrid live the best years of its life. Don’t forget to attend to the needs of your dog and always remember to give them the love and companionship they deserve through love, care, and attention.
