Mastiffs excel at forming deep bonds with their families and demonstrating their protective instincts. This comprehensive breed guide will help you discover more about their amiable demeanor and characteristics.

Mastiff origin

Mastiffs, or as they're sometimes known, Old English Mastiffs, boast a storied past that stretches back centuries in England. Originally bred for their prowess in hunting big game, guarding estates under the cover of night, and even serving in wars, these magnificent dogs have a rich history as formidable protectors.

Today, they're celebrated just as much for their gentle and friendly nature as they are for their impressive size. Having evolved from their ancient forebears, modern Mastiffs are approachable, docile giants known for their kind-heartedness and calm demeanor.

Appearance

Mastiffs are truly a sight to behold with their massive, muscular frames and powerful builds. Their broad skulls, pronounced muzzles, and droopy jowls give them a distinctive, regal appearance. But it’s their expressive eyes, brimming with intelligence, that often captivate onlookers.

These gentle giants wear their short coats in a variety of colors, each adding to their majestic and commanding presence. The most common include fawn, apricot, and brindle. Each of these colors may also come with a black mask around the muzzle and eyes, adding a distinctive contrast to their appearance. Occasionally, you might also see Mastiffs with a small amount of white on their chest, which adds a unique touch to their overall look.

Mastiffs come in a variety of breeds, each with unique traits and origins. The English Mastiff is perhaps the most well-known, celebrated for its immense size and gentle nature. Then there's the Neapolitan Mastiff, originally from Italy, recognized for its loose, wrinkled skin and protective instincts.

The Tibetan Mastiff stands out with its thick fur and formidable appearance, traditionally used to guard livestock in the Himalayas. Meanwhile, the Bullmastiff, a cross between an English Mastiff and an Old English Bulldog, is known for its solid build and loyal temperament, originally bred to help gamekeepers deter poachers.

Each type of Mastiff brings its own special blend of strength, courage, and affection to the families lucky enough to call them their own.

How big do Mastiffs get?

This breed typically stands between 27.5 to 30+ inches at the shoulder. The Mastiffs’ weight ranges from 120 to 230 pounds, with males often becoming larger than females.

Mastiff temperament

Mastiffs are big softies at heart with a protective streak, making them perfect additions to just about any family. They love hanging out with their human pack and are typically very devoted to their people. With their calm and regal presence, they bring a touch of grace to both quiet homes and bustling households alike.

Despite their impressive bulk, Mastiffs are the epitome of chill. They're sharp and always on the alert, but with a protective nature that's more sweet than intimidating. They're typically gentle and loving, especially when they’ve been properly socialized and trained from a young age.

Starting their training early helps them become the well-mannered and confident pets you want them to be. Stick with positive reinforcement, and you'll see your Mastiff grow into a faithful, dependable buddy who's always ready to offer a comforting nuzzle or stand guard.

Common Mastiff health issues

There are several health issues — including hereditary and congenital disorders — that are prevalent among this breed of dog:

Hip dysplasia

Hip dysplasia is a hereditary condition affecting several breeds where the hip joint doesn't develop properly, leading to arthritis and mobility issues. There are often high costs associated with hip dysplasia treatment, and pet insurance may cover this condition with exceptions.

Degenerative myelopathy

Degenerative myelopathy is a progressive neurological disorder that affects the spinal cord, primarily seen in older Mastiffs. It results in a gradual loss of coordination and mobility, eventually leading to paralysis. While there is no cure, supportive care can help manage symptoms and maintain quality of life for affected dogs.

Allergies

Mastiffs are prone to allergies, manifesting as skin irritation, itching, and ear infections. Common allergens include pollen, dust mites, and certain foods. Identifying and avoiding triggers along with appropriate veterinary care and management can help alleviate symptoms and improve the quality of life for dogs suffering from allergies.

Estimated cost to insure

The estimated cost to insure a Mastiff ranges between $40 and $80 a month, depending on age, location, gender, etc.

Mastiffs lifespan

Generally speaking, this breed lives between 6 to 10 years, depending on their health and lifestyle.

The good, the bad, the ugly

Mastiffs possess a plethora of charming traits that endear them to their families. However, it's crucial to weigh the pros and cons of the breed before welcoming a Mastiff pup into your home.

• Gentle giants: Mastiffs are known for their easygoing and docile nature, especially with children and other pets. However, their sheer size means they won't be a perfect fit for all situations.

• Slow and steady: Despite their large size, they have relatively low energy levels and are content with moderate exercise. A daily walk, sure, but it's not too unusual for them to lazily roll on their sides mid-stroll for a nap.

• Go with the flow: They can adapt well to various living environments and lifestyles, whether it’s in a suburban home or a rural setting. They're very patient and typically make great companions for children.

• Bucket and a mop: Mastiffs are notorious for their excessive drooling. They can be messy and require regular cleanup, especially after meals or drinks. Make sure you have XXL napkins on hand.

• Health hurdles: This breed is unfortunately predisposed to certain health issues — such as hip dysplasia, bloat and heart conditions — which may require ongoing medical care and can result in significant veterinary expenses. Consequently, they often have a relatively short lifespan compared to smaller breeds, which can be heartbreaking for those who grow deeply attached to our beloved pets.

So you want a Mastiff ...

Mastiffs are renowned for their affectionate nature and unwavering loyalty. While their care involves attention to potential health issues and ensuring adequate exercise and nutrition, the joy and affection they bring to a household is as big as their stature.
