Birth – 2 Weeks

Born with an average weight of just 1 to 2 pounds, newborn Irish Wolfhound puppies rely heavily on their mother during their first two weeks of life.

This is a crucial stage for growth and development; the tiny pups nearly double in size each week due to a high nutritional intake from mother’s milk.

However, genetics also play a considerable role in determining the puppy’s size at birth, especially its placement within the uterus.

Expectedly, there are often notable variations in sizes within the same litter with some puppies being significantly larger or smaller than their siblings.

Notably though, these early weeks do not necessarily dictate how large your Irish Wolfhound will become as an adult.

3 Weeks – 12 Weeks

In the early weeks of an Irish Wolfhound’s life, significant changes begin to occur.

Between 3 and 12 weeks old, these gentle giants experience their most rapid growth rate. This period is critical in shaping the size your puppy will eventually grow into as an adult.

The weight of a male Irish Wolfhound during this phase can range broadly from 24 pounds at three weeks to as much as 85 pounds by twelve weeks!

Female puppies are slightly lighter with weights varying between 22 and 80 pounds.

Size and color start to become more apparent now, contributing to their overall appearance.

It’s essential that proper nutrition supports this rapid increase in both size and weight.

High-quality dog foods rich in balanced nutrients help foster healthy growth while preventing issues such as hip dysplasia or canine bloat common in larger breeds like the Irish Wolfhound.

So remember, investing in good quality nutrition today can prevent costly health concerns tomorrow!

This stage also marks a crucial turning point for training your furry friend; simple commands learned now forms the foundation for further obedience training courses later on – paving way for well-adjusted dogs capable of heavy exercise needs without signs of nervousness or skittish behavior.

4 Months – 9 Months

This period marks a significant growth phase in the life of an Irish Wolfhound. Their rapid growth rate is evident during these months, with males typically weighing between 82 to 145 pounds and females ranging from 69 to 152 pounds.

This substantial weight increase signifies that your puppy has almost reached its full height by six months, particularly for males who weigh around 80 to 110 pounds and females coming in at about 79 to 107 pounds.

Your pet’s size at this stage can be managed effectively through proper nutrition and regular exercise since the Irish Wolfhound’s health depends greatly on maintaining a healthy weight considering potential health concerns such as hip dysplasia or bone cancer.

Training becomes even more crucial now as they are still maturing slower than most breeds, displaying puppy-like behavior despite their large size – underlining the need for gentle giants like these to have consistent leash training and socializing activities organized by reputable breeders or rescue organizations.

10 Months – 18 Months

During the period of 10 to 18 months, Irish Wolfhounds experience continued growth and maturation. At this stage, their height may not increase significantly, but they continue to gain weight and muscle mass.

By 10 months, male Irish Wolfhounds typically weigh around 110 to 140 pounds, while females weigh about 100 to 130 pounds.

As they approach their first year mark at around 12 months, males can weigh anywhere between 120 to 150 pounds and females may range from around105 to120 pounds.

From there until they reach full maturity at around two years old, both males and females will gradually fill out and develop their adult physique.

It’s important to provide them with a balanced diet rich in nutrients during this critical period of growth.


Once an Irish Wolfhound reaches adulthood, they are truly majestic creatures.

On average, females weigh around 132 pounds, while males can weigh up to a whopping 162 pounds. Their height ranges from 32 to 35 inches, with some variations within the breed.

It’s important to note that size variations among adult Irish Wolfhounds are quite common, with some females weighing as little as 105 pounds.

The growth and development of an Irish Wolfhound don’t stop at their first year.

While most reach their full height at around two years old, gaining another inch or two during their second year, they typically won’t reach their full weight until they’re about three to three and a half years old.

Factors That Affect Irish Wolfhound Growth

Several factors can influence the growth of an Irish Wolfhound, including genetics, gender, nutrition, physical activity, and overall health.

Genetics & Gender

Genetics and gender play significant roles in determining an Irish Wolfhound’s growth. These majestic dogs have a genetic predisposition for their size, so if both parents are large, it is likely that their puppies will be too.

However, it’s important to note that inheritance isn’t as straightforward as just looking at the parents’ size. Other factors such as grandparents and even further back in the lineage can also influence growth.

In addition to genetics, gender also affects a pup’s ultimate size. By four months old, differences between male and female Irish Wolfhounds become noticeable, with males generally being larger than females.


Proper nutrition plays a crucial role in the healthy growth of Irish Wolfhound puppies. It’s important to provide them with a balanced diet that includes the right amounts of calcium, fats, and proteins.

Good nutrition not only promotes healthy bone and muscle development but also supports their overall well-being.

For optimal growth, it’s recommended to feed Irish Wolfhound puppies specialized dog food formulas that prioritize health and quality.

Avoid overfeeding carbohydrates as they can contribute to weight gain and obesity. Instead, opt for high-fiber dog foods that help dogs feel full while controlling their weight.

Always consult with a veterinarian to ensure your puppy is receiving the right nutrients for its age and breed size.

Physical Activity & Health

Regular physical activity is crucial for the overall health and well-being of Irish Wolfhounds. These gentle giants require moderate exercise to keep their muscles toned and maintain a healthy weight.

However, it’s important not to overdo it, as excessive running or jumping can put strain on their growing joints.

As they are prone to certain health issues like hip dysplasia and bone cancer, it’s essential to provide controlled exercise that doesn’t put unnecessary stress on their bodies.

Daily walks, free play in a secure area, and mental stimulation activities such as puzzle toys or obedience training are great ways to keep them physically active while also providing mental enrichment.
