Irish Wolfhound
EYE-rish WOOLF-hownd
Courageous, Dignified, Calm, Gentle. Originally bred for hunting wolves and elk.
An adult Irish Wolfhound weighs 120-180 lbs (male) or 105-140 lbs (female), needs 1,520-3,040 calories daily, and lives 6-8 yrs. Giant breeds grow slowly and need careful nutrition management during their extended puppyhood. The breed's primary health watch is dilated cardiomyopathy. All numbers below come from AKC breed standards and NRC 2006 veterinary nutrition formulas.
Nutrition and feeding
A typical adult Irish Wolfhound needs 1,520 to 3,040 calories per day. An average male (150 lbs / 68.0 kg) needs around 2,320 kcal; a female (122 lbs / 55.6 kg) roughly 1,990 kcal. These estimates use the vet-standard RER/MER formula.

Health profile
Giant breeds have shorter lifespans than smaller dogs, and the Irish Wolfhound is no exception at 6-8 yrs. Their large frames put stress on joints, hearts, and skeletal systems. The breed's primary health concerns are dilated cardiomyopathy and osteosarcoma, which responsible breeders screen for before breeding.
Exercise and activity
Moderate; 30-60 minutes of daily walking. Despite their size, they're not high-energy dogs. Avoid intense exercise in puppies (under 18-24 months) to protect growing joints. Hound breeds follow their noses (or eyes) with single-minded determination. Off-leash exercise for a Irish Wolfhound requires a securely fenced area because recall is unreliable when a scent captures their attention. Nose work, tracking games, and long leash walks through interesting environments channel their natural instincts constructively.
Care and traits
Irish Wolfhounds have a rough, wiry, medium-length coat. Origin: Ireland.
The tallest of all dog breeds. Their tragically short lifespan (averaging 6-8 years) means you never have enough time with them. Irish Wolfhounds are gentle giants who are surprisingly well-suited to indoor living; they curl up small and are calm housemates.
Living space matters for a breed this size. They need room to move without knocking things over, and many giant breeds prefer cool environments. Heat tolerance is limited; monitor closely in warm weather. Elevated food and water bowls may improve comfort during meals.

Frequently asked questions
A healthy adult Irish Wolfhound requires between 1520 and 3040 calories daily. A 150-pound individual falls near the middle of that range. Elevated food bowls are sometimes recommended for giant breeds, though research on bloat prevention is mixed. Slow-feeder bowls are a safer bet. Active hunting hounds burn significantly more than the resting estimate. Adjust for actual activity level. Use our calorie calculator with your dog's actual weight for a personalized number.
Males typically weigh 120-180 lbs (54.4–81.6 kg). Females run lighter at 105-140 lbs (47.6–63.5 kg). Giant breeds should appear muscular and solid but never round. Because they carry so much mass, even moderate overweight significantly stresses joints and shortens lifespan. Check body condition by feeling the ribs (they should be easy to find), viewing from above (waist should narrow behind the ribs), and from the side (abdomen should tuck up behind the ribcage).
If you own a Irish Wolfhound, dilated cardiomyopathy is the condition your vet will likely screen for first. DCM causes the heart muscle to weaken and enlarge. Annual cardiac screening (echocardiogram) can catch it early. Some evidence links grain-free diets to DCM in certain breeds; discuss diet choice with your vet. Other conditions seen in the breed include osteosarcoma, bloat, liver shunt. Regular vet visits with breed-specific screening catch problems when they are most treatable.
A daily routine of 30 to 60 minutes of movement suits most Irish Wolfhounds. Good activities for this breed include scent trails, tracking games, long rural walks. Avoid high-impact exercise (jumping, stairs) during the growth phase to protect developing joints. While not as demanding as high-energy breeds, a Irish Wolfhound that gets no exercise will gain weight and may develop behavioral issues.
