What is the Average Weight of an Irish Wolfhound?

The average weight of Irish Wolfhounds has changed noticeably over time due to selective breeding and evolving breed standards. Historically, these dogs were bred for their size and strength to hunt wolves and protect livestock, often weighing less than today’s show lines. In the 19th century, efforts to revive the breed led to crossbreeding with other large dogs like Great Danes and Scottish Deerhounds, which increased their size significantly. Today, the average weight for a male Irish Wolfhound ranges from 140 to 180 pounds (63 to 82 kg), while females typically weigh between 115 and 140 pounds (52 to 63 kg). This increase reflects a shift from working utility to emphasizing size and presence in the show ring. However, breeders must balance weight with health, as excessive size can lead to joint and heart issues.

Growth Rate Of Irish Wolfhounds By Age

The graph illustrates the rapid growth trajectory of Irish Wolfhounds from birth to three years of age, highlighting the steep weight gain during their first year. Males typically grow from about 15 pounds at one month old to nearly 130 pounds by their first birthday, with females following closely behind. The most dramatic increase occurs between 3 and 9 months, where puppies can double or even triple their weight. After 12 months, growth begins to slow, though both sexes continue to gain weight and muscle mass gradually until around 24 to 36 months, when they reach full physical maturity. This extended growth period, especially in such a large breed, underscores the importance of joint-friendly nutrition, low-impact exercise, and regular vet checks to monitor for conditions like joint dysplasia or panosteitis. Understanding these developmental milestones helps owners and breeders support healthy skeletal and muscular formation during each critical stage.

Impact of Weight on Health

Weight plays a crucial role in the overall health and lifespan of Irish Wolfhounds. While these dogs are naturally large, excessive weight can lead to a host of serious health problems. One of the most common issues is hip dysplasia, a genetic condition worsened by added strain on joints due to extra weight. Similarly, heart disease, particularly dilated cardiomyopathy (DCM), becomes more likely as body mass increases, forcing the heart to work harder. Obesity can also reduce mobility, increase fatigue, and shorten a dog’s lifespan significantly. Because of their rapid growth and massive adult size, managing weight from an early age is essential—not just for physical wellness but also for ensuring comfort and quality of life in later years. Vets often recommend frequent weigh-ins, specialized diets, and joint supplements to keep large breeds like Irish Wolfhounds within a healthy range.

Top 10 Key Considerations for Nutritional Needs Based on Weight in Irish Wolfhounds

1. Caloric Intake Must Match Weight and Activity

Larger or more active Wolfhounds require more calories, but overfeeding can lead to obesity and joint issues. Use weight-based feeding guidelines and adjust as the dog grows or becomes more or less active.


2. Controlled Growth Diet for Puppies

Puppies grow extremely fast, so they need a large-breed puppy formula that supports steady, not rapid, growth to protect joints and bones. Avoid high-calorie, high-fat diets early on.


3. High-Quality Protein for Muscle Maintenance

Lean proteins like chicken, lamb, or fish are vital to support their massive muscle mass, especially as they mature and need to maintain strength without excessive weight gain.


4. Joint Support Supplements

Heavy dogs are prone to hip and joint stress. Look for foods with or add supplements containing glucosamine and chondroitin to support cartilage and joint function.


5. Avoid Excess Calcium in Puppies

Too much calcium can cause skeletal abnormalities in growing pups. Ensure calcium and phosphorus ratios are balanced—ideally 1.2:1 in large breed puppy food.

6. Monitor Body Condition Score (BCS) Regularly

Use a BCS chart to assess if your Wolfhound is underweight, ideal, or overweight. Weight alone doesn’t tell the full story—fat distribution and muscle tone matter too.


7. Frequent, Smaller Meals

Especially during growth stages or for heavier dogs, divide daily food into 2–3 meals to reduce bloating risk and aid digestion, rather than one large meal.


8. Omega-3 Fatty Acids for Inflammation and Coat Health

Diets rich in fish oils or flaxseed can reduce inflammation in heavy joints and improve skin and coat, especially as body weight puts more stress on the frame.


9. Weight-Based Feeding Adjustments Over Time

As Irish Wolfhounds reach adulthood and later, senior age, reduce calorie intake to match their slowing metabolism and avoid unnecessary weight gain.


10. Customized Veterinary Feeding Plans

Given their size and unique health profile, it’s often best to work with a vet to develop a feeding plan that evolves with your Wolfhound’s weight, age, and activity level.
