When Does a Irish Wolfhound Stop Growing?

Most Irish Wolfhounds reach adult height of 30–32 inches by 15–24 months, with full body weight of 105–120 lbs achieved shortly after. Males fill out to 120 lbs while females reach 105 lbs.

Growth rate is influenced by genetics, diet quality, and spay/neuter timing. Moderate exercise needs with daily walks and access to a large yard; strenuous exercise should be limited until they are at least 18 months old..

Is My Irish Wolfhound Overweight?

Is your Irish Wolfhound at a healthy weight? The ideal range is 105–120 lbs (males 105–120, females 89–105). Check these three signs:

  • Ribs: Easily felt with light pressure; not visible but not buried under fat
  • Waistline: A clear narrowing behind the ribs when viewed from above
  • Abdominal tuck: The belly slopes upward from the ribcage to the hind legs when viewed from the side

If your dog fails any of these checks, consult your vet. Tragically short-lived for such a magnificent breed, with heart disease and cancer being the primary causes of their limited lifespan..

Feeding Recommendation

Adult Irish Wolfhounds (105–120 lbs) typically need 1.6 to 2.4 cups of high-quality dry food per day, divided into two meals. Choose a large-breed formula to support joint health and manage the risk of Dilated Cardiomyopathy. Moderate exercise needs with daily walks and access to a large yard; strenuous exercise should be limited until they are at least 18 months old.—adjust portions based on activity level. Budget $90–134/month for food costs.

Use the body condition scoring method: ribs easily felt, visible waist from above, and abdominal tuck from the side. If your Irish Wolfhound exceeds 120 lbs without exceptional muscle mass, they are likely overweight. Obesity is particularly dangerous for this breed due to their predisposition to Dilated Cardiomyopathy. Your vet can provide a precise assessment and weight loss plan.
A Irish Wolfhound puppy growing toward 105–120 lbs needs carefully measured portions. Feed 3–4 times daily until 6 months, then twice daily. With moderate energy levels (3/5), avoid overfeeding to prevent excess weight gain. Monitor body condition weekly and adjust as needed.
If your Irish Wolfhound puppy isn't gaining weight as expected (target adult weight: 105–120 lbs), consult your vet. Common causes include intestinal parasites, insufficient calorie intake, or malabsorption. The breed's predisposition to Dilated Cardiomyopathy could also be a factor worth investigating. A fecal test and blood work are typically the first diagnostic steps.
