The majestic Irish Wolfhound is a gentle giant that can steal anyone’s heart with its size and friendly demeanor. These dogs are known for their impressive height and weight, but when do they stop growing? Generally, Irish Wolfhounds reach their full size between the ages of 18 months to 2 years.

It can take longer for this breed to mature compared to smaller dogs, but the wait is worth it. Many owners of Irish Wolfhounds enjoy watching their pups grow into these amazing creatures, and with proper care and nutrition, they can reach their full potential. If you’re thinking of getting an Irish Wolfhound, be prepared for an adorable, fluffy puppy who will eventually turn into a magnificent companion.

How big will my Irish Wolfhound get?

As a proud owner of an Irish Wolfhound, one of the most common questions people ask is how big will my furry friend ultimately get? While it is difficult to determine the exact height and weight, as each dog is unique, Irish Wolfhounds are known to be one of the largest dog breeds out there.

On average, male Irish Wolfhounds can reach up to 32 inches in height and weigh around 120-180 pounds, while females can grow up to 30 inches and weigh in the range of 105-135 pounds. 

These gentle giants require a lot of space to roam around and ample amounts of food to keep their massive and muscular bodies fueled up, but their loyalty and affection make them worth every ounce of effort put into raising them.

Irish Wolfhounds are massive, imposing creatures that continue to grow for several years after birth. This makes it even more important to understand when your furry friend has reached their full size. To determine whether your Irish Wolfhound has finished growing or not, take note of their weight, height, and general behavior.

If their weight has plateaued, they are standing tall, and their demeanor is settled, then the chances are that they have reached their full size. However, it’s always best to consult with your vet to determine if your Irish Wolfhound is healthy and thriving as it should.

Overall, keep an eye on their physical appearance and behavior, and you’ll know exactly when your Irish Wolfhound has finished growing.

What factors can affect the growth rate of an Irish Wolfhound?

The Irish Wolfhound is a breed known for its towering height and gentle temperament. However, like any other living creature, the growth rate of an Irish Wolfhound can be impacted by various factors.

Genetics plays a significant role in determining the size and health of a Wolfhound, with ancestors’ bloodline playing a crucial part. Nutritional factors such as a high-quality diet are also vital. Insufficient or improper nutrition can cause the puppy to grow slowly or develop bone and joint issues, leading to an overall growth deficiency.

Environmental factors such as living conditions, exercise levels, and socialization can also impact the growth rate of an Irish Wolfhound. A healthy and happy environment that promotes growth and development is crucial for the breed. Understanding these critical factors can help ensure that an Irish Wolfhound grows to be the majestic and healthy breed that we all love and admire.

Can Irish Wolfhounds experience growth spurts?

As one of the tallest dog breeds in the world, Irish Wolfhounds are quite impressive with their regal appearance and gentle nature. However, many owners and potential owners wonder if these dogs experience growth spurts just as humans do during their adolescent years.

The answer is yes! Much like teenagers, Irish Wolfhounds can go through sudden and rapid growth phases, which can leave them looking slightly awkward or clumsy. 

But rest assured, these growth spurts are perfectly normal and usually happen between the ages of six and twelve months. So if you’re thinking of adding an Irish Wolfhound to your family, don’t be surprised if they shoot up seemingly overnight during their puppy years.

How much does an Irish Wolfhound grow in a week?

Irish Wolfhounds can grow up to 1-2 inches in height each week! They reach their full adult size by the time they are 18 months old. Interestingly, even though they remain large dogs throughout their life, Irish Wolfhounds continue to add muscle and bone mass well into adulthood.

So while growth slows down after 18 months of age, they will still gain weight and bulk until they reach around 8 years old. Keeping this in mind when feeding your pup is very important – it’s best to feed them a diet tailored to their size so that they get all the nutrients they need without overloading on calories or having any nutritional deficiencies!

Overall, Irish Wolfhounds have an impressive growth rate and can be quite tall when fully grown! With the right care and nutrition, they can reach their full potential and live healthy, happy lives.


As we’ve seen, the Irish Wolfhound is a majestic and awe-inspiring breed of dog, but their enormous size requires their owners to dedicate additional time and effort to their care and maintenance. On top of that, the fact that they can take up to three years or even longer to reach full maturity is something prospective owners should plan for when bringing a Wolfhound into their home. Nonetheless, when fully grown, these powerful and loyal dogs are an asset to any family and make wonderful companions. If you’re looking for a devoted canine companion who will always be by your side, then consider becoming an owner of an Irish Wolfhound today!

Hi, my name is Magnus Sierra, and I love Irish Wolfhounds!
I’ve been raising these magnificent dogs for a couple of years now and have learned a lot about them. My first Irish named Drake; I was 19 when I decided to adopt him. My vet told me that Irish Wolfhounds are affectionate, loyal, and quite gentle. So when I first adopted Drake, he certainly lived up to this description!
