The Bull Mastiff has been a popular breed in the US and Europe with families that want a low energy guardian for years now though you won’t find them ranking very high in popularity contents. Much of this is thanks to their size and short lifespans. These not-so-high achieving canines are favorites in homes that don't want a flashy high energy canine, but just want a loyal guardian. They are an all-around capable breed but their lazy nature means they aren’t about to hop off the couch and go for a run or learn an agility course anytime soon.
The breed popularity has remained steady in various club rankings for quite a while now. Today, the Bull Mastiff is ranked 51st out of 196 breeds by The American Kennel Club, and part of the working group. Keep in mind that while they are an exceptional breed, they are best for experienced canine leaders that are calm and consistent with boundaries. Bull Mastiffs need 2 to 3 good long but low impact walks each day to exercise them properly and even a couple more when they are young, so be prepared for that commitment. They can do well alone for long periods of time but can turn destructive if they are bored of sleeping, so make sure you watch my other videos on these gorgeous dogs before bringing one into your home.
Now let's get into the size of these heavily muscled dogs because make no mistake, even the smallest are still pretty big. The AKC standards dictate that male Bull Mastiff stand between 25 to 27 inches tall at the withers, while females can be slightly smaller and range from 24 to 26 inches tall. The KC standards dictate that male Bull Mastiff ideally stand at the same 25 to 27 inch range at the withers, and females standing slightly smaller and at 24 to 26 inches tall as well.
The AKC standards dictate that a Bull Mastiff weight should be proportional to their height with males weighing between 110 to 130 pounds and females weighing between 100 to 120 pounds. The KC standards are very similar and dictate that a Bull Mastiff weight should be proportional to their height with males weighing between 110 to 130 pounds and females slightly smaller weighing between 100 to 110 pounds. This variation between UK and US standards is common, and many breeds are somewhat larger in the US than their UK cousins but their ranges overlap here. They are a square and powerfully muscled breed, so they need plenty of low-impact exercises every day along with a high quality diet to stay in shape and avoid becoming obese. I suggest the raw diet and have a course that goes over everything you need to know when considering and transitioning to a raw diet for your canines health and longevity.
The most common health tests relate to hip and elbow dysplasia, which are quite common in Bull Mastiffs, and many other large breed dogs. You may also want to screen for heart defects though they can be hard to test accurately for depending on the potential condition and severity. Because of their size, you'll find that any health issues they do have (and even routine vet visits) can cost more, so quality pet insurance would be a wise investment to consider as well.
They are an overall healthy breed for their short 10 year average lifespan. When going through a breeder you’ll want to get copies of their hip, elbow, ophthalmologist, and thyroid evaluations along with a cardiac exam. They also may have a slightly higher chance of developing cancer or other heart problems so it’s important to be on the lookout for these and feed the highest quality diet possible.
You can expect to pay $1000-$3000 for a well-bred Bull Mastiff from a quality breeder, but you'll find them outside of that range as well, depending on your location, the pedigree, and their registration status. Keep in mind that you'll likely need to invest in training, high-quality food, pet insurance, heartworm medication, and other things that tend to be more expensive given their size. Getting your new Bull Mastiff will be the lowest cost, so be prepared for the ongoing expenses.
