Mastador Growth Chart (Weight Chart & Size Chart)

A Mastador is an unusual dog breed created by crossing a Bullmastiff and a Labrador Retriever. This breed has only been around for around 30 years, but it is believed to have originated in America because both the Bullmastiff and the Labrador are popular dogs in the country.

Mastadors are not little dogs by any means. This is not the dog for you if you want a lap dog that will fit in your small flat. However, if you want a huge, affectionate, and loyal dog who will serve and protect your family, these are the dogs for you.

When Do Mastador Stop Growing?

The Mastador is described as loyal, even-tempered, and affectionate. While they are rarely hostile towards humans or other pets, they are natural defenders who will defend their pack and territory if necessary. They are generally sociable and gentle, and they enjoy participating in family activities.

If they are left alone for long periods of time without human engagement, they can grow bored, restless, and destructive. Although he is normally a quiet dog, his protective nature means he will bark deeply when outsiders approach. In other words, this is not a dog who will fare well confined to a small apartment for an extended period of time.

A Mastador’s final weight will show which breed ultimately dominated your dog’s gene pool: Labrador or Bull Mastiff. As a result, the weight of this dog can range from 100 pounds (typical of the Labrador) to 160 or even 200 pounds for some males (which reflects the Bullmastiff).

Mastador Growth Chart – What To Expect

Mastador 1-2 weeks

Puppies are fully reliant on their mothers for food and care, such as keeping themselves clean, from birth to two weeks. Touch and taste sensations are present at birth. Neonatal puppies have limited mobility and can only crawl at a moderate pace.

Puppies become aware of and interact with their littermates as well as their mother between the ages of two and four weeks. By five weeks, their eyes are open and their vision is fully developed. Their powers of hearing and smell are maturing, and their baby teeth are beginning to emerge. Puppies begin to walk, bark, and wag their tails at this stage. Puppies are able to excrete without the assistance of their mothers at the conclusion of this phase.

During this stage, weaning from the mother also begins. Puppies should be introduced to solid food around the age of three weeks. In a shallow bowl, give the puppies little amounts of soft food. By the age of eight weeks, the puppies should be consuming solid food and no longer breastfeeding.


Mastador 3-12 weeks

Puppies continue to be impacted by their mother and littermates between the ages of four and six weeks. They learn to play and obtain necessary social skills from their littermates, such as restricted biting (biting to play, not to hurt). The puppies also learn the ins and outs of group structure and group ranking. During this time, puppies become significantly louder, with the development of play barking and snarling.

If the mom is violent or scared of others at this point, the puppies may be affected by her demeanor. Have a variety of people interact with your puppies to socialize them with humans – young (with supervision) and old, male and female. It’s also critical to expose your puppy to other regular activities throughout the socialization period, including car rides, crate training, vacuuming, ringing doorbells, and a range of items and sounds. Handling of the feet and body parts is very beneficial for a puppy to learn at a young age.


Mastador 4-6months

Puppies grow quickly at this time, and you may observe everyday changes. Even though pups are highly energetic, don’t over-exercise him because he can overdo it. Puppies begin to employ ranking in their group structure among themselves – that is, they begin to test where they fit in. 

Puppies may go through another panic period that lasts about a month and appears out of nowhere. Again, this is a totally normal phase of puppy development and is not cause for concern.


Mastador 10-12 months

Puppies, like other adolescents, are rambunctious, so keep training and socializing your dog during this stage. Socialization and training are required if you want your puppy to feel at ease and behave appropriately in public locations such as dog parks and beaches, or anywhere she will meet new canines and humans.


Mastador Adult 

Your dog has attained adulthood by this age, however, changes in social preferences and habits can occur up to two years of age. Ongoing training will guarantee that your dog has a polite and enjoyable interaction with all human family members, making having an animal in the family a daily delight.

How To Weigh Your Mastador Puppy?

If you want to maintain track of your Mastador’s weight, you must first learn how to weigh him properly.

To begin, you should be able to weigh your Mastador at home if he is a puppy or if you are just large enough to hold him. This can be accomplished with a standard bathroom scale.

To begin, weigh yourself and record the result. Then, while standing on the scale, pick up your dog and hold him. The difference in weights represents your dog’s weight.

If your dog is too huge to carry, you can either invest in a dog scale, which can cost upwards of $100, or contact your veterinarian. The majority of veterinarian offices will enable you to use their scale.

Unless there is a health problem, you can weigh an adult Mastador once every six months. Once a week is sufficient for a puppy to ensure he is growing normally.

What Is A Mastador’s Neck Size?

To determine the neck size of your dog, use a soft and flexible tape measure to determine the neck size of your dog where her collar naturally falls. Then, put two fingers between your dog’s neck and the tape measure to ensure that the dog collar fits snugly but comfortably. Mastador’s average neck circumference is between 18 and 24 inches.

However, forecasting a dog’s adult size without a crystal ball might be difficult. After all, it is influenced by a slew of variables, including:

Breed. Unsurprisingly, breeds account for the greatest variation in adult height and weight among dogs. There’s a reason why you seldom see 50 lb. Breeders must achieve specific standards for their litters to be recognized as purebred, whether they are Chihuahuas or miniature Mastiffs.

Status as a neuter/spay. According to research, neutering or spaying a dog before the age of nine months appears to slightly boost its adult size, whilst neutering after that age appears to significantly lower it. This is most likely due to the hormonal response to the operation.

Sex. Adult male canines are slightly larger than their female counterparts across breeds.

Factors That Affect Mastador Puppy Growth 

Diet & Nutrition

The Mastador, like all dogs, requires a well-balanced diet to keep healthy and happy. These pups will thrive on high-quality dry dog food. Naturally, not just any chow will suffice for a gentle giant like this one. As a general rule, these designer dogs perform best when based on a formula for large, athletic breeds. Furthermore, the kibble you select should be appropriate given their age. A huge breed puppy growing quickly will need to eat a certain sort of diet that an adult or senior Mastador would not.

The Mastador, as a large, energetic dog, will require roughly 2-1/2 to 3 cups of high quality dry food each day. Because they frequently mimic the “Labrador” and eat everything in sight, it’s critical to ensure that, while your dog is adequately fed, the amount is limited to ensure his weight stays optimal.

If you are concerned about establishing or changing your dog’s diet, it is always a good idea to consult with a veterinarian first. While dog food manufacturers and pet bloggers offer helpful feeding advice, these are only guidelines and should not be taken as gospel. A vet is the only person equipped to identify your dog’s exact dietary needs, so always seek their advice before making any significant adjustments to what goes into your puppy’s food dish.

Physical Activity & Health

While most hybrids are fortunate not to inherit their parents’ health difficulties, the Mastador can be prone to large dog illnesses such as hip dysplasia and cardiac problems later in life. Furthermore, if the ears of this floppy-eared dog are not cleaned on a regular basis, they can develop infections and stinky odors. As usual, it’s critical to keep up with frequent vet exams to ensure that any potential health issues are discovered and treated as soon as feasible.

Because this is a huge, robust dog, owners must plan daily walks and energetic playtimes. He may be an indoor or outdoor dog, but while he enjoys a nice stroll or frolic in the snow, he does not fare well in cold weather for long periods of time and should not be considered if you wish to have an outdoor dog. Those who intend to let him out in the yard should be aware that Mastadors are superb jumpers and may easily scale a fence. As a result, larger fences of six to eight feet will be required if you do not intend to supervise.

Common Questions about Mastador

How Long Are Mastadors Pregnant?

Since conception in dogs lasts roughly 63 days, this can vary by several days. Despite the fact that this may appear to be a simple answer, conception is often difficult to pin down. It’s possible for sperm and eggs to remain fertile for up to 48 hours after fertilization, thus the act of mating isn’t a precise assessment of pregnancy. This makes it difficult to estimate the length of the pregnancy without the help of a vet.

The gestational period can be pinpointed much more precisely using hormone assays. To keep track of reproductive hormone levels, many breeders utilize vaginal smear exams and blood tests. They can use this information to figure out when is the best time to breed their buck, how long she will be pregnant, and when she might give birth.

How Many Puppies Do Mastadors Have?

A Mastador will live for an average of 10-15 years, with a litter size of 6-10 puppies.


What Is The Life Expectancy Of Mastadors?

Your Mastador should survive for about 10-15 years. While most hybrids are fortunate not to inherit their parents’ health difficulties, the Mastador can be prone to large dog illnesses such as hip dysplasia and cardiac problems later in life.

How Much Does It Cost To Own AMastador?

Mastadors are a distinct breed that is still quite uncommon. As a result, you may expect to spend a premium for a Mastador puppy. Prices range between $900 to $2,000. However, various factors, like the lineage and health of the parents, the overall health of the puppies, and the reputation of a breeder, might influence the actual price you spend.

If you want to possess a Mastador, don’t settle for the first one you come across, even if it’s cheap. Take the time to do your research and save up the money if necessary to ensure you’re purchasing a puppy from a respectable breeder.

How To Help Your Mastador Lose Weight If He Is Overweight 

As with humans, exercise is critical for your overweight dog’s health. Increased movement helps your dog burn off excess energy (and calories consumed). Avoid panic! Exercising your pet does not have to include marathons or lengthy hikes. Regular walks and the opportunity to run and play safely off-leash. 

Even creating a stimulating indoor environment that encourages your dog to exercise on a regular basis can help. Bear in mind that different breeds require varying amounts of exercise, so visit your veterinarian, breeder, or your dog’s breed standard for recommendations on recommended activity levels.

Distinguish Begging from Hunger

Distinguish Begging from Hunger
Distinguish Begging from Hunger

Begging is not necessarily motivated by a desire for more food; it is also used to gain attention. (And, by rewarding the behavior, you reinforce and encourage it to continue.) If your dog begs, do not automatically assume he is hungry. Trust your instincts and keep track of the date and time of your last meal. 

If your dog is prone to begging and you are prone to succumb to those puppy dog eyes, choose a high-protein meal with a fiber blend to help control your dog’s hunger and voluntary food consumption. This manner, you may feed your dog with the assurance that he will feel fuller and content for a longer period of time.

Restriction on treats and table scraps

Even when our dogs are not begging, many of us provide an excessive amount of treats and table scraps. Dogs are not required to share our food! Consider treats and scraps for your pet in the same way that you would candy for children to help you keep them in check. If you’re going to utilize snacks for training, choose low-calorie, low-fat ones and keep the portions small. 

As an alternative, keep in mind that clickers are excellent for reinforcement… and they have no calories! After all, a few extra pounds can make a significant impact in the lives of dogs, which are significantly smaller than humans. (Even the colossal breeds!) Therefore, focus on a balanced diet and resist the temptation to “reward” them with extra.

Customize Your Dog’s Diet

Not all weight-loss foods are created equal, which is why it’s critical to match your dog’s nutrition plan to their unique needs. Choose a brand that caters to your dog’s unique needs, whether they be weight control, dietary sensitivities, or illnesses.

These gentle giants will be an excellent companion and watchdog for your family for many years.
