Key Takeaways

  • Mastiffs require experienced owners: Their size, protective instincts, and potential health issues mean they're not ideal for first-time dog owners. A large space, consistent training, and financial preparedness are essential.
  • Prioritize your Mastiff's health: Be aware of breed-specific health concerns like bloat, joint problems, and certain cancers. Regular vet checkups and a proper diet are vital.
  • Research and connect with other Mastiff owners: Finding a reputable breeder is crucial. Understanding their temperament, exercise needs, and potential challenges will help determine if a Mastiff is right for you. Communities like Sniffspot offer valuable support and advice.

Origins of the Mastiff

The Mastiff breed has a rich history that dates back to ancient times. Originally from England, these impressive dogs were used as guardians and warriors, known for their strength and bravery. They were highly valued by the Romans, who likely brought them to Britain and further developed their impressive size and protective instincts.

In medieval England, Mastiffs were used in battles and as guard dogs for estates. Their formidable presence made them effective at warding off intruders and defending their homes. They were also popular among the nobility, who admired their loyal and protective nature.

Over time, the breed evolved from a fierce warrior to a more gentle companion. Despite their imposing size, Mastiffs are known for their calm demeanor and loyalty. Today, they continue to be cherished for their protective qualities and affectionate nature, making them both impressive guardians and beloved family pets.

Ancient History and Blood Sports

The Mastiff’s history goes back thousands of years, with evidence of similar dogs existing 3,000 years ago across Europe and Asia. These weren't the gentle companions we know today. Mastiffs served as guard dogs, hunting dogs, war dogs, and even participated in blood sports like fighting other animals (bulls, bears, and even lions!). It's a stark contrast to the gentle giants we now cherish, but understanding this history provides context for the breed's evolution.

The Bandog Connection

Older texts often used "Mastiff" and "bandog" interchangeably. A bandog wasn't a specific breed, but a dog kept chained (bande) during the day and released at night for protection. This practice contributed to the Mastiff's reputation as a formidable guardian. The Bull Mastiff breed resulted from an English bandog breeding program, linking these historical practices to a modern breed.

Mastiffs vs. Livestock Guardian Dogs

While some large livestock guardian dogs like the Pyrenean, Spanish, and Tibetan Mastiffs share characteristics with Mastiffs, they are genetically and historically distinct. The "Mastiff" in their name doesn't automatically make them true Mastiffs. This is an important distinction when understanding breed classifications—shared traits don't always indicate shared ancestry.

The English Mastiff's Development

The English Mastiff we know today largely developed during the 1800s through careful breeding programs. These programs focused on refining the breed's temperament and appearance, shifting from its fighting past to its role as a loyal companion. Influential breeders and specific dogs shaped the modern English Mastiff into the gentle giant we love.

Mastiffs in America

The first Mastiff may have arrived in America on the Mayflower. These dogs quickly became known as natural guardians of family and home. Despite their size, Mastiffs are rarely aggressive, truly embodying the term "Gentle Giants." They're known for their calm nature and loving interactions with children and other animals.

Mastiff Ownership: What to Expect

As a Mastiff owner, it’s important to know the best dog breed tips and what to expect from current Mastiff owners.

Mastiff Grooming Guide

Mastiff dogs require low maintenance grooming. This means Mastiff owners should expect minimal grooming, like occasional brushing and baths. Mastiff dogs have a short coat, which is ideal for protection. Their short coat is considered moderate shed.

To keep your Mastiff’s coat healthy and up to breed standards, include brushing in their daily routine and clean their ears regularly to avoid infections. Of the coat types for common breeds in the guardian group, the grooming needs for Mastiffs are considered to be low maintenance.

Mastiff Exercise Requirements

Mastiffs require low activity each day. Though one of the most popular dog breeds, English Mastiffs are considered a very athletic, high-energy breed. English Mastiffs make great pets and thrive with around 30 minutes of walks and playtime a day. Owners of English Mastiffs report their dogs especially love tug-of-war, playing with squeaky toys, and chasing/playing with a ball or frisbee.

When large breeds like English Mastiffs don’t get sufficient exercise, they’re more likely to act out with undesirable behaviors like aloofness or stubbornness. They need consistent training, mental activity, and regular low exercise to avoid excess energy.

Feeding Your Mastiff

What should you feed your Mastiff to keep them healthy? As a low-energy breed, what you feed them is important. A reported 47% of our community feed their English Mastiff commercial dry kibble.

With low exercise, English Mastiffs should eat 4 to 6 cups of vet-recommended food to maintain a healthy weight of around 120 – 230 lbs. However, your Mastiff’s ideal weight and food depend on your pet’s sex, activity level, and age.

Preventing Bloat

Mastiffs are particularly susceptible to gastric dilatation volvulus (GDV), commonly called bloat. This serious condition can be life-threatening and requires immediate veterinary attention. Symptoms include restlessness, an enlarged abdomen, and unproductive retching (trying to vomit). If you see these signs, contact your vet immediately. Knowing the signs of bloat and acting quickly is crucial for Mastiff owners.

Feeding your Mastiff several smaller meals throughout the day, rather than one large meal, can help reduce the risk. This strategy helps prevent the stomach from twisting, a key factor in GDV (Hill's Pet). For some high-risk Mastiffs, preventative surgery might be an option to discuss with your veterinarian (Lassen Veterinary Services).

A consistent feeding routine and close attention to your Mastiff’s health are essential for preventing bloat and ensuring a long, happy life for your dog. Regular exercise also contributes to their overall well-being. A private dog park through Sniffspot can be a great way to provide a safe and enriching environment for your Mastiff to play and get the exercise they need.

Common Mastiff Health Issues

The Mastiff breed is most prone to joint problems (e.g., hip dysplasia, arthritis) and skin conditions (e.g., allergies, dermatitis). A reported 43% of our Mastiff owners reported joint problems like arthritis, elbow dysplasia, degenerative issues, and osteosarcoma. English Mastiff’s risk for these challenges increases as they age.

Similarly, 28% reported skin conditions like allergies, yeast infections, impetigo, ringworm, alopecia, and folliculitis. Lastly, 23% of Mastiff owners claim their dog struggles with ear infections caused by allergies, ear mites, or contact dermatitis — a common English Mastiff health concern. If you’re worried about any of these health issues above, talk to your English Mastiff’s vet.

Eye Conditions

Like many large breeds, Mastiffs can be prone to certain eye conditions. These include entropion (where the eyelids roll inward), cataracts (a clouding of the eye lens), and progressive retinal atrophy (PRA), a degenerative disease affecting the retina. Because these issues can significantly impact your dog’s quality of life, regular veterinary checkups are key. Early detection and management are crucial for mitigating the effects of these conditions. Learn more about Mastiff health from resources like PetMD.

Cancer in Mastiffs

Sadly, Mastiffs are also susceptible to various types of cancer. Osteosarcoma (bone cancer), lymphoma (cancer of the lymph nodes), hemangiosarcoma (cancer of the blood vessels), and mast cell tumors are among the cancers that can affect this breed. Early detection through regular vet visits and being aware of any unusual lumps or bumps is absolutely crucial for effective treatment. Resources like Lassen Veterinary Services offer further information on breed-specific health concerns.

Other Health Concerns

Beyond eye conditions and cancer, Mastiffs are at higher risk for several other health issues. These include hip dysplasia (a common joint problem in large breeds), degenerative myelopathy (a progressive disease of the spinal cord), epilepsy (a neurological disorder causing seizures), and gastric dilatation volvulus (GDV), commonly known as bloat. GDV is a life-threatening condition where the stomach twists, cutting off blood supply. Given their predisposition to these conditions, maintaining regular vet checkups is essential for your Mastiff’s well-being. PetMD is a great resource for learning more about these specific health concerns.

The Importance of Vet Checkups and Pet Insurance

Preventative veterinary care is the cornerstone of responsible Mastiff ownership. Regular checkups allow your vet to monitor your dog’s overall health, catch potential problems early, and discuss preventative measures. Because veterinary care for larger breeds can sometimes be more expensive, pet insurance is highly recommended. It can help cover the costs of unexpected illnesses or injuries, providing peace of mind and ensuring your Mastiff receives the best possible care. Lassen Veterinary Services emphasizes the importance of both regular vet visits and pet insurance for Mastiffs.

Emergency Symptoms

Knowing the signs of a medical emergency can save your Mastiff’s life. Symptoms like restlessness, a noticeably enlarged abdomen, and unproductive retching (trying to vomit without producing anything) can indicate GDV (bloat), a condition requiring immediate veterinary attention. If you observe any of these symptoms, don’t hesitate to contact your vet or an emergency animal hospital immediately. PetMD provides more information on GDV and other emergency situations in dogs.

Are Mastiffs Good Family Dogs?

Another important thing to consider when adopting an English Mastiff is whether or not they fit with your current family. How friendly are Mastiffs compared to other large-sized breeds?

With consistent training, you can hone your English Mastiff’s guardian instinct into a protective and affectionate family dog. Introducing your pet to positive reinforcement (treats, praise, rewards) and consistent daily training routines early helps them avoid undesirable behaviors like aloofness or stubbornness. Our community Mastiff owners comment on their pet’s friendliness:

  • People don’t understand how dominant they like to be, you really have to let them know you are in charge from the beginning. (RMW)
  • Takes the right training to ensure a good temperament. (Halle)
  • Big dog big mess, destroys things inside the house when not looking. (Sabrina )

Mastiffs and Children

Mastiffs are known for their gentle nature, earning them the nickname "gentle giants." Our 2024 Sniffspot Community Breed Survey revealed that Mastiff owners consider these dogs incredibly loving and excellent family pets, especially when introduced to children at a young age. One respondent affirmed, "The Mastiff is also known to be very friendly and social with children." Early socialization is key to a harmonious relationship between your Mastiff and kids. Choosing a dog name together as a family can also enhance bonding.

While generally good with children, Mastiffs' large size means they could accidentally knock over a small child. Supervise interactions, especially between younger children and your Mastiff, to prevent unintentional injuries. Teaching children how to interact respectfully with dogs is also crucial. This includes understanding dog body language and avoiding behaviors that might provoke a negative reaction, even in a gentle breed like the Mastiff.

Mastiffs and Other Pets

Our Sniffspot Community Breed Survey from 2024 shows Mastiffs are generally friendly and social with other pets. However, their protective instincts, while valuable for guarding, require careful management. Early socialization with other animals is essential to help your Mastiff build positive relationships with other household pets. This includes supervised introductions and positive reinforcement when your Mastiff behaves appropriately around other animals.

Consistent training is vital in shaping your Mastiff's protective instincts into affectionate companionship. One Sniffspot user noted, "With consistent training, you can hone your English Mastiff’s guardian instinct into a protective and affectionate family dog." Connecting with a qualified dog trainer can be especially helpful if you have multiple pets or are introducing a Mastiff into a home with existing animals. Even with training, supervision is always recommended, especially during initial interactions, to ensure everyone's safety and comfort. Providing a safe and enriching environment, perhaps with designated spaces like those you can find on Sniffspot, can further contribute to a harmonious multi-pet household.

Training Your Mastiff

Whether you’re adopting an English Mastiff puppy or an adult Mastiff, training is a significant part of owning a large-sized breed. Without proper training, your English Mastiff is more likely to display undesirable behaviors such as aloofness or stubbornness. Providing stimulating activities is a great first step, but this needs to be paired with the right training for your English Mastiff.

As a guardian breed, Mastiffs benefit from praise and positive reinforcement. Here’s what our English Mastiff community recommended based on their experience with their own dogs:

  • Positive Reinforcement (92%): This includes treats, praise, rewards, and so on for positive behavior
  • Consistent Routines (58%): A consistent training routine allows your pet to get comfortable with expectations
  • Socialization (42%): Socializing your dog with other pets, dogs, and people prepares them to interact with the world

As dogs bred for guarding and fighting, English Mastiffs are considered highly trainable by all types of dog owners.

Early Socialization and Obedience Training

Training is a significant part of owning a large-sized breed like a Mastiff. Without proper training, your English Mastiff is more likely to display undesirable behaviors such as aloofness or stubbornness. Socializing your dog with other pets, dogs, and people prepares them to interact with the world. This is especially important with a breed like the Mastiff, known for its protective instincts. Early exposure to a variety of sights, sounds, and experiences will help them develop into well-adjusted adults. Consider checking out Sniffspot's dog parks for safe and controlled socialization opportunities.

Beginning obedience training as early as possible is crucial. Focus on basic commands like sit, stay, come, and down. Working with a qualified dog trainer can be invaluable in establishing a solid foundation for training. With consistent training, you can hone your English Mastiff’s guardian instinct into a protective and affectionate family dog. Introducing your pet to positive reinforcement (treats, praise, rewards) and consistent daily training routines early helps them avoid undesirable behaviors. Remember, even gentle giants need guidance to become well-behaved members of the family.

Positive Reinforcement Techniques

Positive reinforcement is a highly effective training method for Mastiffs, with 92% of Sniffspot owners recommending it. This approach focuses on rewarding desired behaviors with treats, praise, or toys, creating a positive association with training. A consistent training routine allows your pet to get comfortable with expectations. This consistency helps your Mastiff understand what is expected of them and builds a strong bond between you and your dog. Even short, regular training sessions are more effective than sporadic, longer ones.

While positive reinforcement is key, socialization plays a vital role too, with 42% of owners emphasizing its importance. Socializing your Mastiff with other pets, dogs, and people prepares them to interact with the world. Dog parks, especially those with designated areas for large breeds, can be excellent for socialization. As dogs bred for guarding and fighting, English Mastiffs are considered highly trainable by all types of dog owners. This makes them receptive to positive reinforcement techniques and allows you to shape their behavior effectively. By combining positive reinforcement with consistent training and socialization, you can nurture your Mastiff into a confident, well-behaved companion.

Why Mastiff Owners Adore Their Dogs

We asked Sniffspot English Mastiff owners what they love the most about their Mastiff pups, and here’s what they had to say:

  • Incredibly affectionate and big enough for full-body snuggles. (Sarah )
  • Incredibly loyal and affectionate with her people, highly intelligent, and thinks her sole job is to please me. (SJ)
  • Affectionate and loyal, medium energy level, won’t get bored and eat the couch. (Anon)

Challenges of Mastiff Ownership

Similarly, English Mastiff owners shared some of the biggest challenges of living with their Mastiff:

  • They are BIG, therefore, training is a MUST! They can be very stubborn and independent. And the slobber can be a big challenge as well (Anon)
  • Challenging breed, not recommended for first-time dog owners. Lots of behavioral challenges if not socialized correctly at a young age. (LW)
  • Reactivity. Sometimes they are blinded by what’s a real threat versus not. Hence training is key with this breed. (Ashley)

Is a Mastiff Right for You?

Mastiff Dog Breed - Sniffspot User Survey - are mastiffs right for first-time dog owners?

Source: Sniffspot 2024 Community Dog Breed Survey

According to 75% of our Sniffspot community, Mastiffs are not a great first-time dog. This comes from their protective nature and large size. Mastiff owners say it best:

  • We haven’t had any challenges at all in her almost 4 years but I think size could be a challenge for some. Ours instinctively knows to be gentle around kids but has stepped on some toes accidentally and that does hurt little feet. (Laura)
  • Reactivity. Sometimes they are blinded by what’s a real threat versus not. Hence training is key with this breed. (Ashley)
  • A reactive mastiff is a terrifying prospect because that’s a human-sized dog that other owners will perceive as “going after” their dog, even if they are the ones with an off-leash dog in a designated on-leash area. (Sarah)

Space and Financial Considerations

Given their size, English Mastiffs need their space. Think large! According to our 2024 Sniffspot Community Breed Survey, 91% of Mastiff owners said a large house with a fenced yard is ideal. A fenced yard is key—you don’t want your gentle giant wandering off to explore the neighborhood on their own. While a large house is preferred, 28% of owners find that a more rural or suburban environment with open spaces also works well. If you have a smaller home but access to safe, open areas where your Mastiff can stretch their legs and roam, it can be a good fit. Check out Sniffspot's listings for ideas on dog-friendly parks and open spaces near you.

Financially, be prepared. Beyond the initial adoption or purchase costs, there are ongoing expenses to consider. Food is a major one. With their lower exercise needs, English Mastiffs typically eat 4 to 6 cups of vet-recommended food per day to maintain a healthy weight of between 120 and 230 pounds, according to our internal research. Factor in the cost of high-quality dog food, regular vet checkups, potential medications, and toys and treats.

Understanding Their Protective Instincts

Mastiffs are known for their protective instincts. It’s in their DNA! They were originally bred as guardians, so it’s natural for them to be watchful and wary of strangers. This doesn’t mean they’re aggressive, but they are serious about protecting their family. The key is to channel those instincts positively through training and socialization.

Positive reinforcement is crucial, as highlighted by our Sniffspot breed research. Praise, treats, and rewards go a long way in shaping their behavior. Consistent training from a young age helps them understand expectations and builds a strong bond between you and your dog. For tips on training, check out our resources on top dog trainers. Early socialization is also essential. Exposing your Mastiff to different people, dogs, and environments helps them become well-adjusted and confident adults. While Mastiffs can be challenging, especially for first-time owners (as noted in our research), with the right approach, you can nurture their protective nature into a loving and devoted companionship.

Tips for Mastiff Owners

Luckily, our Sniffspot community is full of experienced, trustworthy English Mastiff owners. These Mastiff breed owners share the most essential dog breed tips and advice for prospective or new dog owners:

Finding a Reputable Breeder

When considering adding a Mastiff to your family, finding a reputable breeder is crucial. A responsible breeder prioritizes the well-being of their dogs and adheres to ethical breeding practices, including health screenings and proper care. Start your search with breed-specific organizations like the Mastiff Club of America, which often have breeder referral programs and helpful resources. You can also explore online communities like Sniffspot to connect with other Mastiff owners and gather recommendations.

Transparency is essential when evaluating a breeder. They should openly answer your questions about health testing, pedigree information, and the puppies' upbringing. Don't hesitate to ask for documentation, such as health clearances and pedigree papers. Organizations like the North American Mastiff offer guidance on finding ethical breeders and avoiding scams.

Visiting the breeder's facility, if possible, is invaluable. This allows you to observe the living conditions firsthand and see how the puppies are raised. A clean, well-maintained environment and healthy, sociable dogs are positive indicators. Meeting the parents can offer insights into their temperament and potential health concerns. Resources like Happy Dog Breeds provide further information on selecting a responsible breeder.

Finally, ask for references from previous puppy buyers. Speaking with other families who have purchased puppies from the breeder offers valuable firsthand perspectives. These conversations can provide reassurance and help you make a well-informed decision. Finding the right breeder is an investment in your future Mastiff's health and happiness, so take your time and do your research.

Early Training is Key
  • Training and socializing – it never ends. Get started early and do it often. This breed needs a job and structure. It’s a lot of work if you aren’t committed to putting the time in a Cane Corso isn’t for you. (FB)
  • Make sure you’re ready to handle a dog of this size. (SJ)
Are You Ready for a Mastiff?
  • If others are considering this breed definitely consider the size of these dogs as well as training commitment up front. This breed is also a guardian protection breed, their minds are built to be skeptical of new people and loyal to you. Not a dog that is going to be happy-go-lucky around everyone. (LW)
  • They need to be with their people a lot of the time, their size alone = $$ food, vet, care, etc. be prepared financially. But be prepared for a best friend for life. Incredibly loyal and affectionate – make a great family pet with a calm demeanor. Very sweet when properly socialized. (Alana)
Picky Eaters?
  • You will sweep up more dog hair than you could ever imagine; you need to have somewhere cold for him to sleep at night; his food requirements change daily (one day wants frozen beef and the next day cooked chicken; doesn’t like the same thing two days in a row). (Karyn)
  • You need a lot of time, patience, and money (because many medications are by weight). You also have to be prepared for the heartbreak of them not living as long as other breeds. They’re not “”stubborn””; you have to understand and work with their particular motivations and breeds are not a monolith. The dogs within a breed are still individuals with preferences. (Sarah )
The Ideal Lifestyle for a Mastiff
  • You need extra time for training consistently, good for families with PROPER socialization, and make sure your dog does not think he is the alpha of the house (the owner is). (MiKayla )
  • You need to know what you’re signing up for and understand it is a lifestyle breed that needs a lot of training, exercise, and mental stimulation. They also feel very unhappy being left alone for long periods. They want to be with their family. (S. P)

Mastiff Breed Variations

Mastiffs aren't a single breed, but a whole group of breeds with shared ancestors and traits. Think of it like a big family reunion—lots of different personalities, but a common thread connects them. The term "mastiff" covers several distinct breeds, each with its own quirks and origins. If you're thinking about welcoming a mastiff into your life, understanding these variations is key.

The Mastiff family tree has roots in many different places and times. From ancient war dogs to modern-day companions, mastiffs have adapted and evolved alongside us. Their history is woven into human history, reflecting their changing roles in various societies (Wikipedia).

The English Mastiff

The English Mastiff, often called simply the Mastiff, hails from Britain. This gentle giant is likely descended from ancient breeds like the Alaunt and Pugnaces Britanniae, with some Alpine Mastiff added to the mix in the 19th century. Known for their calm temperament and unwavering loyalty, English Mastiffs are a popular choice for families. You can find resources and connect with other Mastiff owners on platforms like Sniffspot.

Other Mastiff Varieties

While some large livestock guardian dogs, like the Pyrenean, Spanish, and Tibetan Mastiffs, sometimes get lumped in with mastiffs, they're actually genetically and historically distinct (Wikipedia). This is an important distinction for potential owners. Different breeds have different temperaments and care needs. Do your research to find the best fit for your lifestyle. If you're looking for a place for your Mastiff to run and play, check out Sniffspot's dog parks for safe and enriching environments.
