Mastiff American Staffordshire Terrier Mix 101If you’re looking for a pet similar to the American Pit Bull Terrier but can’t get your hands on one, then you might like the Mastiff Staffordshire Terrier mix. This hybrid breed takes two of the biggest dogs around, the Mastiff and American Staffordshire Terrier, which results in a dog with strong jaws but makes for a great companion. In this article, we share everything you need to know about these Mastiff mix breeds and how you can care for them once you’ve decided to bring one of these big boys home.   

What is the Mastiff Staffordshire Terrier Mix? 

The Mastiff Staffordshire Terrier mix is known by many names, including Amstiff, Staffy Bull Bullmastiff, American Bandogge, and Staffordshire Bull Bullmastiffs. While they may be far from being the most popular dog breeds, these sensitive dogs are actually gentle giants that are easy to maintain in terms of grooming. They’re also excellent guard dogs that need regular exercise to keep them happy and healthy.

This can take the form of jogging or walking on a leash, but they will also be happy to play inside a fenced-in yard. These adaptable dogs can be kept inside an apartment but they’ll need moderate exercise to ensure they stay out of trouble and prevent boredom. Moreover, the Mastiff Staffordshire Terrier mix can be a great family dog provided that it is given proper training and socialization.    

History of the Mastiff Staffordshire Terrier Mix

An interesting thing about these dogs is that they share similar origins, yet they’ve become two completely different breeds. Because both parent dogs are well known in the dog world, there’s extensive information on their history and origins. 

American Staffordshire Terrier

These dogs were first created in the 19th and 20th centuries and were mainly used for entertainment purposes back when dog fighting was still legal here in the United States. While the Am Staff has been recognized by the American Kennel Club (AKC) since 1936, it isn’t recognized by the United Kennel Club, which is why it’s also categorized under the Pit Bull Terrier breed. Despite what the media wants us to think, the American Staffordshire Terrier isn’t truly aggressive, and will often become family dogs in farms where they serve as guard dogs. 

They excelled both as raiders and defenders against both wild pigs and bears; it was due to their bravery and fearlessness that made them ideal for such work. Today, these canines are still working dogs, but you’re more likely to see them as a happy-go-lucky family companion.  


These canines are believed to have descended from the Molossus dogs which were introduced to the British Isles from Phoenician trading ships around 2000 and 1500 B.C. In 55 B.C., Mastiffs helped to defend against the Roman invasion and Julius Ceasar became impressed with their large size and courage. He brought them to Rome where they fought against gladiators and lions — centuries later, they would be used in pit fighting as well as bear and bull baiting.   

Today’s Mastiffs are the descendants of these Molossus dogs along with the Lyme Hall Mastiffs; this breed first came to the spotlight when the dog of Sir Peers Legh was noticed after he was mortally wounded in battle. His Mastiff defended him hour after hour and was able to return home with a litter of puppies. These dogs were selectively bred to get desirable qualities, which resulted in a docile and large dog that was recognized by the AKC in the late 1800s.   

Mastiff Staffordshire Terrier Mix Appearance

Because these dogs are a relatively new breed, there aren’t many standards in place to keep this breed in check. However, you can expect the Mastiff Staffordshire Terrier mix to get characteristics from both parent breeds. The Amstiff looks larger than an American Staffordshire Terrier, but a few will come with the broad head of the Mastiff. 

Most males can grow between 14 to 27 inches at the shoulder and weigh around 38 to 130 pounds, while females can grow to the same height but will weigh less at around 14 to 27 inches by the shoulders. These dogs come with a short coat that’s straight along with a dense undercoat that’s available in various colors that were taken from their parents; these colors include:

  • Fawn
  • Red
  • Black
  • White
  • Blue
  • Apricot

Moreover, these dogs can come with white or black markings around the face, body, and neck. These physical attributes make these large breeds good options for guarding the family and your home.   

Mastiff Staffordshire Terrier Mix Temperament 

Even though their parents are such different breeds, there are similarities between the two, including the fact that they’re gentle giants. This means that their offspring will also inherit their protective nature, especially with children — this intelligent breed should be socialized at an early age to help them become well-rounded adults. Because they’re wary of strangers, they’re known to step in between their owners and new people if they feel there’s a threat. 

While the Mastiff can be a bit more stubborn compared to Staffordshire Terriers, both breeds will benefit from obedience classes. Your canine partners will need firmness, patience, loving, and consistent correction. If you’re the right match for this breed, you can be sure to get a loyal dog that will be part of the family in all aspects. 

Mastiff Staffordshire Terrier Mix Care

The best way for dog owners to care for these mixed-breed dogs is to understand their needs. Luckily, we’ve done the research for you and have compiled all you need to know below. 


The ideal diet for a larger dog such as the Mastiff Staffordshire Terrier mix should be formulated for big dogs with moderate energy levels. Much like with any dog your pup’s needs will change as it transitions from puppyhood to adulthood, and even into their senior years. For adults, you should give it high-quality dog food that can be commercially made or made fresh from your kitchen.

Unfortunately, some dogs will be more prone to weight problems than others, so be sure to watch your dog’s eating patterns to ensure that it doesn’t overeat. If you’re still unsure about the best food to feed your pet, speak to your veterinarian about the right options and how often you should feed your canine companion.     


The Mastiff Staffordshire Terrier mix will have coats that are a combination of their parents; they will come with sleek and short coats that will shed throughout the year, so they’re not the best choice for allergy sufferers. But because they have such short coats, they’re easy to groom and will only need weekly brushing. Moreover, their short coats won’t make them a good candidate to live in areas with extreme temperatures, and their short muzzles could lead to breathing problems. 

Your dog’s ears will also need love so check their ears for pests and debris weekly and clean them as instructed by your vet — you should also trim your dog’s nails once or twice a month. You should also help your pup get used to brushing their teeth while they’re young, this will help to keep dental issues away from your pup and will ensure that their oral health is in top shape. If this is your first time owning a dog, your vet will be able to help you care for your dog the right way, and regular veterinary check-ups can help detect health concerns early on.  


The energetic and athletic Mastiff Staffordshire Terrier mix will require much exercise but leaving them out in the yard every day isn’t the best approach. While they will run around to their heart’s content, they are people pleasers who will thrive in the presence of their family. Giving them long play sessions with their favorite humans will give them a psychological and physical boost — these dogs’ parents can snatch a national championship in various dog sports. 

They will likely be a good choice for agility, dock diving, and obedience; they’ve even been trained in search-and-rescue missions where they excel. Unfortunately, a lazy Mastiff Staffordshire Terrier mix will tend to gain weight as a result of their parents’ temperament. To combat this, make sure that your pup gets a minimum of 30 minutes to 1 hour of exercise each day along with some playtime by the yard. 


Puppy training classes, along with early socialization are key for these breeds since they come with a blend of physical strength, exuberance, and a strong will. Thankfully, their eagerness to please and high intelligence balances this out, making their training a fun and easy process. While they’ll quickly learn basic commands, keep in mind that certain behaviors such as digging and chewing may be difficult to get rid of. 

Some aggression may also develop even with dogs that are well-socialized, and they shouldn’t be left alone with other dogs under any circumstance. These dogs will respond well to positive reinforcement methods, so be sure to give them lots of praise and some treats. Just remember that too many treats can contribute to obesity, so try not to feed them human foods, and keep an eye on the amount of calories dog treats carry.  

Mastiff Staffordshire Terrier Mix Health Problems

While the Mastiff Staffordshire Terrier mix is generally a healthy breed as a result of its hybrid genes, it can be predisposed to a few genetic conditions that their parents may also face. This is why it’s important to maintain their health and go on regular vet visits. Below are just a few common health concerns that your pooch may encounter over its lifetime:

  • Hip dysplasia
  • Progressive retinal atrophy
  • Entropian eye
  • Elbow dysplasia
  • Luxating patella
  • Gastric dilation volvulus
  • Cataracts

Living with a Mastiff Staffordshire Terrier Mix 

Because both parent breeds tend to grow big and have a robust body shape, it’s important to have them socialized at a young age to ensure they become responsible around kids. As a result of their sheer size, it’s essential to supervise play sessions and to ensure safety around the home. Their protective instincts will surely play a role in the safety of children and other family members, but it’s important to train them to suppress their high prey drive, or they may start chasing small animals.

When it comes to other pets, these dogs, unfortunately, won’t get along with them, including other dogs. Even when you give them plenty of socialization, it’s not their nature to want to share the spotlight with other animals in one household. While this may not be the case with every single dog, you might get lucky once you’ve given them lots of training and socialization, so your specific pooch may be able to tolerate something that others can’t. 

Looking for a Mastiff Staffordshire Terrier Mix 

If you want to ensure the health of your little one, you’ll need to do research on the best dog breeders around your area. While this may be the more pricey route, speaking with a responsible breeder will help guarantee that the dog you take home will be free from genetic conditions and will be in top shape. However, you can also opt for adoption and look around rescue groups so you can give a pup in need a new home. 


Now that you know all you need about caring for these dogs, it’s time to look for your Mastiff Staffordshire Terrier Mix. Just make sure that you will give them regular brushing, and that you’re familiar with the health issues they might face. The right dog may just be right around the corner; as owners, it’s up to us to ensure that they get the love and care they deserve no matter whether they’re purchased or adopted.
