His parents are very different from one another, but together, they have created a designer doggy who is well-balanced, polite, fun, and sweet. He gets along with other dogs, and he is suited to families with young children, and very adaptable.

But, he isn’t suited to everyone. You will need a large home with access to a private yard if you want to make this boy happy. Size doesn’t always matter, but it will for this guy. He also needs a strong-willed owner who can show him the ropes. And to ensure that he understands that he is the pet dog and not the boss.

The Mastidoodle is considered a Designer Dog and was likely introduced back in the 1980’s when this practice first began. These dogs are the result of mixing and matching different pure-breeds to produce puppies that carried the desired traits of both parent breeds – typically a healthier, smaller, hypo-allergenic or gentler form of a popular breed.

The Mastidoodle comes from two different purebred dogs and as a result, isn’t eligible to join the American Kennel Club (AKC). However, both parent breeds are long-time members; the Mastiff joined the AKC’s “working” group back in 1885 followed shortly after by the Poodle who joined the AKCs “non-sporting” group in 1887.

Diet and Nutrition

  • The Mastidoodle is a large dog with an equally large appetite. He will consume between four and five cups of food every day, depending on his age, size, and activity levels. His monthly food bill is not going to be cheap, that’s for sure.
  • Like his Mastiff parent, he is likely to be a greedy pup, and he will eat anything and everything in sight. If you don’t want him to eat you out of house and home, or you want to avoid expensive vet bills, you need to keep food under lock and key. This guy doesn’t care if it’s toxic. If it fits in his mouth, he is going to swallow it.
  • You should feed him a diet that is specifically designed for large breed puppies. This is particularly important during puppyhood. This is because they contain the optimum nutrients that large and giant dogs need, and they help to control his rapid bone growth. In turn, this could decrease his chances of developing bone diseases such as hip dysplasia.

How easy are Mastidoodle to train?

  • The Mastidoodle will need to be socialized well as a pup if you want him to grow into a polite and confident puppy. As you already know, his Mastiff genes might make him a little overprotective, but his Poodle influence should calm this down. But with ample socialization and obedience training as a pup, this shouldn’t be an issue.
  • Mix him with as many other dogs and animals as you possibly can when he is young, and this will teach him that most dogs are friends and not foe. Also, mix him with unfamiliar humans, as well as new sights and sounds, and this will increase his confidence too.
  • He can be a stubborn dog, and so you need to be persistent with your training. Never give in to a Mastidoodle, because as soon as you do, he’ll remember that he can win you over. Keep training sessions fun and engaging. And with a treat in your hand, he will do as you say, most of the time.


When fully grown, the Mastisdoodle’s weight will reflect whichever of his parent breeds is more prominent. As a result, he could weigh as little as 55 pounds or as much as 100 pounds if he leans more toward the Mastiff.

How would you describe the temperament of Mastidoodle?

The Mastidoodle is a sweet-natured, gentle giant of a dog that once socialized gets along well with kids, other animals and new faces. This smart boy can become easily bored and distracted making him a handful to train and destructive when left on his own for long periods. A family where a member works from home, puzzle toys and interactive playtime can help alleviate this. His protective nature makes him quick to bark to warn owners of a stranger turning him into an ideal non-aggressive watchdog.

How healthy are Mastidoodle?

  • Mixed breeds are a good choice if you’re looking to avoid common hereditary diseases that often run in purebred lines.  However, all breeds have the possibility to develop some health problems.
  • Some major concerns with the Poodle Mastiff Mix include entropion, elbow dysplasia, and canine hip dysplasia.  While not as prominent, some other possible health problems that may develop include progressive retinal atrophy, cataracts, hypothyroidism, and Addison’s disease.
  • Due to the cost of treating these common health concerns, we highly encourage all dog owners invest in pet insurance. We recommend getting a free online quote from Healthy Paws Pet Insurance.

How long will Mastidoodle live?

Your Mastidoodle is a relatively healthy dog that will typically live between 9 and 12 years which is typical for most large dogs.

How active are Mastidoodle?

  • The Mastidoodle is an energetic dog for his size. You need to set aside at least an hour every day for his exercise routine. His exercise doesn’t need to be too intense, and it shouldn’t be either to protect his heavily laden joints. But a long and brisk walk around your local park or neighborhood will suffice for most of the week.
  • Because he is an intelligent and active dog, you should mix up his activities to keep him interested. A simple change of scenery or a frequent visit to a local doggy park to meet new friends will benefit him. And it will top up his socialization skills too.
  • Being a doodle mix, he will be fond of the water, so you should try to include this in his exercise routine. He will love you for it, trust us. Just remember to pack plenty of large towels to dry him down, especially if you don’t want to ruin your vehicle upholstery.

Recognized Clubs

Also known as the Mastipoo, Mastiffpoo and Mastiffdoodle, the Mastidoodle is not recognized by the American Kennel Club (AKC) however he is a member of the Designer Breed Registry (DBR and the International Designer Canine Registry (IDCR).


The Mastidoodle will typically have the shorter, denser and curly coat of the Poodle which means he will be a low- to moderate-shedder and require moderate maintenance including brushing 1 to 2 times per week to keep his coat looking its best. Because of his Poodle DNA, his curly and often corded coat will require regular trips to the groomers and as a floppy eared dog he will be prone to ear infections, so owners should plan to inspect and clean his ears weekly.


The cute little Mastidoodle puppy will quickly grow into a large pooch that can be a handful if he hasn’t been properly socialized. Start training this pup while he is still young, ensure he is comfortable with new faces and other animals and that he understands you are his pack leader. Because he may be prone to joint issues later in life, leash training and exercise should be careful to not over-tax tiny limbs.
