If you are a proud owner of an English Mastiff, you might be curious about their growth stages.
As one of the largest dog breeds, it’s important to understand the different stages of growth that your Mastiff will go through.
From puppyhood to adulthood, your new friend will experience significant changes in size, weight, and appearance.
During the first few months of life, your English Mastiff puppy will experience rapid growth.
According to LoveYourDog, your puppy will gain an average of 2-4 pounds per week during their first few months.
By the time they reach six months of age, your Mastiff will likely weigh between 70-100 pounds.
As they continue to grow, it’s important to provide them with a healthy diet and plenty of exercise to support their growth and development.
As your English Mastiff enters adolescence, their growth will begin to slow down.
However, they will continue to gain weight and muscle mass as they approach adulthood.
By the time your Mastiff reaches their full size, they may weigh anywhere from 120-230 pounds, depending on their gender and genetics.
Understanding these growth stages will help you provide the best possible care for your furry friend throughout their life.
Birth to Weaning: The First Weeks
Congratulations on your new English Mastiff puppies! The first few weeks of a puppy’s life are critical for their growth and development.
In this section, we will explore what to expect during the birth to weaning stage, including understanding newborn Mastiff puppies, nutritional needs, and health care.
Understanding Newborn Mastiff Puppies
Newborn Mastiff puppies are born with their eyes and ears closed. They are completely dependent on their mother for warmth, nutrition, and care.
During this time, it is important to keep the puppies warm and dry. Make sure they are in a clean and comfortable area, away from drafts.
It is also important to monitor the puppies’ weight gain during this stage. A healthy newborn Mastiff puppy should weigh between 1.5 to 2.5 pounds.
If you notice any significant weight loss or lack of weight gain, it is crucial to consult with a veterinarian.
Nutritional Needs and Health Care
During the first few weeks of life, newborn Mastiff puppies rely on their mother’s milk for nutrition.
It is important to ensure that the mother is well-fed and hydrated to produce enough milk for her puppies.
Around three to four weeks of age, Mastiff puppies start to develop teeth and begin the weaning process.
At this point, you can introduce soft and moistened puppy food to their diet. Gradually decrease the amount of milk they receive from their mother.
It is important to monitor their health during this stage. Keep an eye on their eyes and ears for any signs of infection or inflammation.
Make sure they are up-to-date on their vaccinations and deworming.
In summary, the birth to weaning stage is a critical period for your Mastiff puppies’ growth and development.
Make sure they are well-fed, warm, and dry. Monitor their weight gain and health closely. Consult with a veterinarian if you have any concerns.
Puppy Growth: 2 to 6 Months
During the first few months of life, your puppy will go through a period of rapid growth and development.
It’s important to provide your puppy with the proper care and attention during this time to ensure they grow up healthy and happy.
Rapid Growth and Development
As mentioned, during the first few months of life, your English Mastiff puppy will experience several growth spurts.
They will gain weight quickly, so it’s important to monitor their weight to ensure they are growing at a healthy rate.
You can use a weight chart to track your puppy’s growth and make sure they are on track.
Your puppy will also experience significant bone and joint growth during this time.
It’s important to provide your puppy with plenty of exercise and activity to help strengthen their bones and joints.
However, it’s important not to over-exercise your puppy, as this can cause damage to their developing bones and joints.
Socialization and Early Training
Socialization and early training are crucial during the first few months of your puppy’s life. This is the time when they are most receptive to new experiences and learning.
It’s important to expose your puppy to different people, animals, and environments to help them become well-adjusted and confident adults.
Early training is also important during this time. You can begin teaching your puppy basic obedience commands, such as “sit” and “stay.”
Positive reinforcement training methods work best with English Mastiffs, as they respond well to praise and treats.
Providing your English Mastiff puppy with plenty of toys and mental stimulation is also important during this time.
Mastiffs are intelligent dogs and need plenty of mental stimulation to stay happy and healthy.
Overall, the first few months of your English Mastiff puppy’s life are a critical time for their growth and development.
With proper care, attention, and training, your puppy will grow up to be a happy and healthy adult.
Adolescence: 6 to 18 Months
Congratulations! Your English Mastiff has made it through puppyhood and is now entering adolescence.
This stage is marked by significant changes in your dog’s behavior, physical growth, and health.
In this section, we’ll discuss what to expect during this period and how to help your Mastiff thrive.
Behavioral Changes and Training
During adolescence, your English Mastiff will experience a surge of hormones that can cause changes in their behavior.
They may become more independent, stubborn, and even aggressive.
It’s essential to start behavioral training during this stage to ensure your Mastiff grows into a well-behaved adult.
Obedience training is a crucial aspect of behavioral training. Positive reinforcement is the most effective method for teaching your Mastiff obedience.
Use treats, praise, and toys to reward good behavior. Consistency is key, so make sure to train your Mastiff every day.
Physical Growth and Health Monitoring
Your English Mastiff will continue to grow during adolescence, but at a slower rate than during puppyhood.
By 18 months, your Mastiff will reach their adult height and weight milestones.
It’s essential to monitor your Mastiff’s growth using a growth chart to ensure they are developing correctly.
During adolescence, your Mastiff’s health is also at risk. They are susceptible to hip dysplasia, a genetic condition that affects the hip joint.
Regular visits to the veterinarian are essential to monitor your Mastiff’s health and catch any potential health issues early.
In conclusion, adolescence is a critical stage in your English Mastiff’s development.
By starting behavioral training and monitoring your Mastiff’s growth and health, you can ensure they grow into a well-behaved and healthy adult.

According to A-Z Animals, adult male Mastiffs can weigh between 160 and 230 pounds, while females are smaller, weighing between 120 and 170 pounds on average.
At this point, you should transition your dog to adult food and monitor their weight. Overfeeding is common in this breed, so make sure to avoid it.
Mental Maturity and Continued Training
While your Mastiff has reached full physical maturity, mental maturity is still developing.
It is important to continue training your dog during this stage to ensure they are well-behaved and obedient.
According to Love Your Dog, leash training and basic commands should be reinforced during this stage.
Your Mastiff is a patient breed, but it is important to be consistent with training to ensure they continue to behave well.
During this stage, your Mastiff may also become more protective of their family and home.
It is important to socialize them with other people and animals to ensure they are well-adjusted and friendly.

As your English Mastiff ages, it’s important to monitor their weight and make sure they are getting enough exercise.
Obesity and being overweight can lead to health problems such as joint pain, heart disease, and cancer.
Make sure to consult with your veterinarian to determine the appropriate amount of food and exercise for your dog’s needs.
To maintain a healthy weight, consider feeding your English Mastiff a high-quality, well-balanced diet.

However, be mindful not to overdo it, as excessive exercise can be harmful to your dog’s joints.
Monitoring Health and Aging
As your English Mastiff ages, it’s important to monitor their health and watch for signs of aging.
Regular check-ups with your veterinarian can help catch any health issues early on.
Some common health problems in senior English Mastiffs include joint pain, cancer, and bloat.
Joint pain is common in older dogs and can be managed with medication, supplements, and lifestyle changes.
Cancer is also a concern in older dogs, so it’s important to watch for any unusual lumps or bumps and have them checked by a veterinarian.
Bloat, a life-threatening condition, can also occur in older dogs, so it’s important to be aware of the symptoms and seek immediate veterinary care if necessary.
In conclusion, maintaining your English Mastiff’s physical and joint health is crucial as they age.
By monitoring their weight, providing appropriate exercise, and staying on top of their health, you can help your furry friend live a happy and healthy life in their senior years.

Genetic Factors and Growth
The growth and development of English Mastiffs are heavily influenced by genetics.
According to a growth chart for English Mastiffs, they typically reach their full height by the time they are 18 months old, but they may continue to gain weight until they are 3-4 years old.
However, it’s important to note that these are just general guidelines, and each individual dog may have a slightly different growth pattern.
Common Health Issues and Prevention
Like all giant dog breeds, English Mastiffs are prone to certain health issues.

To prevent hip dysplasia, it’s important to only get your English Mastiff from a reputable breeder who screens their dogs for this condition.
Another health concern in English Mastiffs is obesity. Due to their large size, English Mastiffs require a lot of food, but overfeeding can lead to obesity, which can cause a variety of health problems.
To prevent obesity, it’s important to feed your English Mastiff a healthy diet and make sure they get plenty of exercise.
Finally, English Mastiffs are also prone to cancer. While there is no way to completely prevent cancer, you can reduce your dog’s risk by feeding them a healthy diet, providing plenty of exercise, and taking them to the vet for regular check-ups.

To prevent this, it is important to expose them to a variety of people, animals, and environments.
This will help them become comfortable in different situations and prevent them from becoming overly attached to one person.
Socialization Milestones and Tips
