What is a North American Mastiff?
The North American Mastiff is a giant beast with an equally big heart. This incredible and imposing pooch was designed to be a healthier version of the original Mastiff, the English Mastiff.
The American Mastiff dog breed is fairly new, but you’ll still find many breeders offering these pups for sale. That’s because their superior health, low drooling, and impressive physiques have made them very popular among pet owners in a short time.
Combine that with their calm temperament and excellent guarding ability, and you have a canine that’ll protect you and your property with his life. So, let us tell you all about this wonderful breed; this is American Mastiff dogs 101.
North American Mastiff history
Mastiffs descend from ancient warrior dogs. When they weren’t helping, they served as guardians. After they arrived in the USA, but strict adherence to breed standards led to inbreeding, and their health deteriorated over time.
The North American Mastiff is pretty new on the canine scene. This pooch was developed in the 1980s by Ohio breeder Fredericka Wagner. Wagner bred English Mastiffs with Kangal Shepherds to produce the North American Mastiff — an equally massive canine with better health and improved life quality. After a while, she ended external crossing and began using her own stock to reproduce them.
Is the North American Mastiff recognized by AKC and UKC?
The North American Mastiff is a recent breed and hasn’t yet received AKC or UKC recognition.
Nonetheless, several canine clubs consider them purebred, including the Continental Kennel Club. There have been some hindrances in getting the North American Mastiff AKC recognition, but fans of this breed are optimistic that they’ll be able to get their pup AKC-registered in the coming years.
American Mastiff vs English Mastiff
Although they’re both similarly heavy-boned and giant canines, the American Mastiff varies in several ways from the original English Mastiff. Some prominent differences are:
Weight: Although the North American Mastiff can grow taller, the English Mastiff is more massive. English Mastiffs are among the heaviest canines in the world.
Build: Although both canines are thick, the English Mastiff has a bulkier appearance. Compared to them, the North American Mastiff seems slimmer.
Facial features: English Mastiffs have a very wrinkly appearance and loose lips, whereas North American Mastiffs have tighter skin and lips.
Drooling: English Mastiffs are notorious for their high drooling, but North American Mastiffs drool far less due to their tighter lips.
AKC recognition: North American Mastiffs haven’t received AKC recognition yet, whereas the English gained AKC recognition in 1885.
Breed history: The English Mastiff has been around for centuries, whereas the North American Mastiff is only a few decades old.
Health: The primary reason for breeding North American Mastiffs was eliminating the English Mastiff’s health issues. North American Mastiffs have better health than their English counterparts.
Are North American Mastiffs the same as Panja American Mastiffs?
Many people confuse the North American Mastiff with the Panja American Mastiff. Although these two canines look alike and have similar names, they’re separate breeds.
The North American Mastiff is purebred with links to English Mastiffs and Kangal Shepherds. In contrast, Panja American Mastiff is a mixture of several dog breeds, including Pitbulls, Mastiffs, Bandogs, and Rottweilers.
The North American Mastiff is a relatively new breed raised to be gentle companions. On the other hand, the Panja American Mastiff had its reputation severely tarnished.
North American Mastiff as working dogs
The North American Mastiff’s parentage traces to two excellent working breeds: English Mastiffs and Kangal Shepherds. The North American Mastiff is a similarly obedient and intelligent breed that excels as a protector and watchdog. Whether it’s thieves, trespassers, or wild animals, your North American Mastiff will have no problem dealing with them.
North American Mastiff physical appearance
The North American Mastiff inherits most of his physical attributes from the English Mastiff; however, keen eyes canine enthusiasts can notice distinctions between them and their English relatives.
These giant canines are somewhat leaner than other Mastiffs, but they tower above most dogs. They have slightly thinner and longer snouts than Mastiffs. Their necks are muscular, their bodies are evenly proportioned, and they have an overall beefy look.
North American Mastiff coat colors
North American Mastiffs come in similar colors as regular Mastiffs. Standard American Mastiff colors include:
The fawn, apricot, brown, and black American Mastiff colors are common, whereas brindle and merle are harder to come by. Let’s discuss these two colors.
American Mastiff brindle
Brindle is a coat pattern rather than a color. It usually has vertical stripes of light color over a dark base coat. You can also say that brindle is an inverted version of tiger stripes.
North American Mastiff merle
Merle is a semi-dominant gene that causes a pooch to have random patches of a dark color over a light coat. Since the gene is semi-dominant, the patches are solid at some places and diluted at others. A merle North American Mastiff is likely crossbred as merle isn’t a natural color for them.
North American Mastiff size
Mastiffs are enormous, and the North American Mastiff is among the largest canines in the world. Everything about them is massive and intimidating: from their large heads to huge jaws to towering height.

North American Mastiff height and weight

North American Mastiff temperament and personality
The Mastiff personality is a stark contrast to how they look. These canines are calm, affectionate, and level-headed despite seeming like ferocious beasts. They aren’t very energetic and prefer lounging around the house. However, they can sense threats quickly and immediately come to their owner’s protection.
The American Mastiff temperament is in many ways similar to English Mastiffs. They’re gentle, protective, tolerant, quiet, and courageous. They don’t bark much, and with their imposing size, they hardly need to. They can act stubborn and be difficult to train, which is why they’re best suited to experienced owners.
Do North American Mastiff get along with other pets?
The North American Mastiff is instinctively protective of their owner’s property, which includes other animals. That’s because their ancestors were used for guarding livestock. These massive canines may not mingle with other pets a lot, but they’re not a threat to them either. Still, their huge bodies mean they can inadvertently hurt smaller animals.
North American Mastiff training
Training is perhaps the most challenging aspect of owning a North American Mastiff. These pups are strong-willed and get bored easily. They are fully aware of their size and can sometimes challenge your authority.
However, they’re also sensitive, and excessive strictness will have negative results. Training them requires a firm hand. You need to be authoritative and patient. Don’t get angry when training your pup.
North American Mastiff exercise requirement
The North American Mastiff’s big, heavy body isn’t built for speed or agility. Stick to gentle walks in parks. The North American Mastiff isn’t always keen on exercising and would rather lay around all day. This can cause them to gain weight, leading to a host of health issues.
Make sure your North American Mastiff gets half an hour of light exercise daily.
North American Mastiff grooming and cleaning
Grooming your North American Mastiff isn’t challenging; they’re good with just one brushing session per week. However, their large bodies mean you have a lot of areas to cover.
Coat: Bathing your North American Mastiff once every two months is enough.

Nails: Check their nails regularly and keep them clipped short.
Ears: You should also check their ears for unhealthy earwax buildup.
Teeth: Brush their teeth regularly to keep cavities at bay.
Is the North American Mastiff hypoallergenic?
No, the North American Mastiff is not hypoallergenic. Although the North American Mastiff sheds minimally, their loose fur carries dander. Dander is dead bits of skin that trigger allergies in people.
However, regular grooming at home and in-between grooming appointments can take care of that. These pooches drool less than other Mastiffs, which is also a plus.
North American Mastiff food and diet
The North American Mastiff needs high-quality dog food to fulfill the needs of his massive body. Go for a protein-rich diet with lots of vitamins, minerals, and other micronutrients. Avoid fatty foods and snacks as they can trouble your pup’s tummy.
North American Mastiff common health issues
1. Joint dysplasia
Hip and elbow joint deformation can cause the bones to rub against the bone, leading to wear and tear. Joint dysplasia is a hereditary condition and can end with a complete loss of mobility.
2. Pulmonic Stenosis
Pulmonic stenosis is when the pup’s heart cannot pump blood adequately to the lungs. Unfortunately, it’s a common congenital issue among Mastiffs.
Bloat is well-known among large dogs. Eating too fast can cause the pooch to swallow excess air. This air combines with stomach gas to inflate your pup’s tummy. It then twists, which cuts off its blood supply.
4. Skin issues
Mastiffs have sensitive skins, and the North American Mastiff isn’t any different. Skin issues like allergies, mange, hives, and dermatitis often plague the breed.
Hypothyroidism is when the body’s thyroxin levels fall too low. It can lead to hair loss, weakness, weight gain, and indigestion, among other things.
6. Bone cancer
Cancer, especially bone cancer isn’t easy to detect, but family history can give you a good idea. Always check the medical record of the parents when adopting a puppy.
7. Heart diseases
Cardiac issues like mitral valve disease, subaortic stenosis, and cardiomyopathy can significantly reduce your North American Mastiff’s lifespan.
Cataracts cause the dog’s eye to form a cloudy layer over the lens, obstructing his vision. Although it isn’t painful, it can lead to blindness. Cataracts require surgical removal.

Progressive Retinal Atrophy or PRA is another eye problem that can cause deteriorated vision, often leading to complete blindness.
10. Bone deformities
These heavyset canines can suffer from several bone and joint issues, especially later in their lives. Bone deformities may be congenital, or they can be caused by obesity.
Ectropion is when the dog’s eyelid folds outwards. This exposes the sensitive inner skin and causes irritation.
Entropion is similar to ectropion, except the eyelid turns inwards instead of outwards. The folded eyelash rubs against the eyes, damaging the lens.
