Monitoring the development of your Mastiff is crucial for their well-being. Regularly recording their weight and height and comparing these measurements to the breed’s standards can provide insights into their health. 

Puppy Growth Timeline

Developing a Mastiff puppy is a steady journey that requires time, patience, and regular training.

The puppy depends entirely on its mother for sustenance for two weeks. This period is vital for the puppy as it starts to hone its senses and motor abilities.

Around one month of age, the puppy begins to socialize with its littermates and is introduced to wet food. This is an essential time for the puppy to learn social skills and develop a healthy relationship with food.

At two months, the puppy is separated from its mother and begins obedience training. This is when the puppy will learn basic commands and start to bond with its owner.

From three to ten months of age, the puppy will experience monthly growth milestones. It is crucial during this time to continue training and socialization to establish good behavior and prevent any bad habits from forming.

When the puppy is one year old, it is time to celebrate its first birthday! The puppy will continue to grow and develop but at a slower rate.

It is essential to continue training and socialization throughout the dog’s life to ensure a well-behaved and happy Mastiff.

What Happens After a Year?

Mastiffs are known for their unique growth pattern, characterized by rapid growth during the first year of life. When a Mastiff reaches one year old, it will have grown substantially. 

However, despite this impressive growth rate, Mastiffs are not fully grown at one year old.

Mastiffs typically grow until they reach about five years of age. While their growth rate slows after their first year, they continue gaining weight and size. 

During this growth phase, keeping an eye on a Mastiff’s development is crucial to ensure they’re growing healthily and not becoming overweight. 

Proper nutrition and exercise are vital for Mastiffs as they grow. Feeding them too much or too little can result in health issues like joint problems and obesity. 

Collaborating with a veterinarian to create a personalized nutrition and exercise regimen for your Mastiff is essential.

Full-Grown English Mastiff

There are general size guidelines for a fully grown English Mastiff. The American Kennel Club (AKC) suggests that male Mastiffs should be at least 30 inches tall at the shoulder, whereas females should measure at least 27.5 inches. However, these figures are merely guidelines and individual Mastiffs might vary.

Weight is another crucial aspect when determining the size of a mature Mastiff. Males usually weigh between 160 and 230 pounds, while females range from 120 to 170. 

It’s essential to remember that these are average figures, and some Mastiffs might be below or above these typical ranges.

It’s also worth noting that the AKC has specific standards for Mastiff height. According to these standards, a male Mastiff should be between 30 and 36 inches tall at the shoulder, while a female should be between 27.5 and 32 inches tall. 

However, it’s important to remember that these are just guidelines, and individual Mastiffs may fall outside these ranges.
