The Irish Wolfhound and Great Dane are both giant dog breeds with rich histories. Irish Wolfhounds have ancient roots in Ireland, whereas Great Danes, despite their name, originated in Germany. Both breeds faced near-extinction at different points in history. The Irish Wolfhound almost disappeared in the 19th century when wolves became scarce in Ireland, but dedicated breeders worked to revive the breed.

Great Danes gained popularity in the 1800s as companion dogs. They became known as “German Mastiffs” in many countries. After World War II, they were renamed “Great Danes” in English-speaking nations. Today, you’ll find both breeds recognized by the American Kennel Club (AKC) with the AKC officially recognizing the Great Dane in 1887 and the Irish Wolfhound in 1897. Let’s explore these two dog breeds.

Great Danes and Irish Wolfhounds are massive dogs with striking features. Their size and appearance set them apart from most other breeds. Let’s look at how these gentle giants compare physically.

Great Danes stand tall at 28-34 inches for males and 28-32 inches for females. Irish Wolfhounds are even taller, with males reaching 34-35 inches and females 32-34 inches.

Weight-wise, Great Danes typically range from 110-175 pounds. Irish Wolfhounds can weigh 105-180 pounds.

Great Danes have short, smooth coats that are easy to groom. You’ll find them in various colors:

  • Fawn
  • Brindle

Irish Wolfhounds sport a rough, wiry coat that’s longer than a Great Dane‘s. Their coat colors include:

  • Gray
  • Brindle
  • Red
  • Black
  • White
  • Fawn

Both breeds shed moderately. You’ll need to brush your dog weekly to keep their coat healthy.

Temperament and Personality

Great Danes and Irish Wolfhounds have distinct personalities. Their temperaments shape how they interact with people and other animals.

Affectionate Nature

Both breeds are known as gentle giants. Both breeds are also good with children when raised together. Their size means supervision is important to prevent accidental bumps.

  • Great Danes are very loving and enjoy being close to their families.
  • Irish Wolfhounds are also affectionate but can be more reserved.

Prey Drive and Hunting Instinct

  • Great Danes have a lower prey drive. They were bred as companion dogs rather than hunters. This makes them easier to manage around small pets.
  • Irish Wolfhounds have a stronger hunting instinct. They were originally bred to hunt large game like wolves. You’ll need to be careful with small animals around them.

Socialization Needs

  • Great Danes are usually friendly with people and other dogs.
  • Irish Wolfhounds require more socialization. 
  • Both breeds benefit from puppy classes and regular outings. This helps them become well-adjusted adult dogs.
  • Proper socialization prevents anxiety and aggression in these large breeds.

Health and Lifespan

Both Great Danes and Irish Wolfhounds face health challenges due to their large size. These giant breeds have shorter lifespans compared to smaller dogs. Let’s look at their common health issues and breed-specific concerns.

Common Health Issues

Giant dog breeds often deal with joint problems. Let’s take a look at the health issues most common with these dogs.

  • Hip dysplasia is a major concern for both Great Danes and Irish Wolfhounds.
  • Heart problems are also common in large breeds.
  • Bloat, a dangerous stomach condition, is another risk.

Health Concerns by Breed

  • Cardiomyopathy, a heart muscle disease, is a serious concern for Great Danes.
  • Irish Wolfhounds often deal with bone cancer, which can shorten their lifespan. 
  • Liver shunt is another condition to watch for Irish Wolfhounds.

When it comes to lifespan, Irish Wolfhounds typically live 6 to 8 years. Great Danes have a slightly longer life expectancy of 8 to 10 years. Regular vet check-ups and proper care can help your giant dog live a healthy life.

Care and Maintenance

Great Danes and Irish Wolfhounds need specific care due to their size. You’ll need to focus on exercise, grooming, diet, and training to keep these gentle giants healthy and happy.

Exercise Needs

  • Both breeds need regular exercise to stay fit. Great Danes require 30-60 minutes of daily activity. Irish Wolfhounds need more exercise, about 1-2 hours per day.
  • These giant dogs enjoy running in large, fenced areas. Be careful not to overexert young dogs, as it can harm their developing joints.
  • Puzzle toys and indoor games can provide mental stimulation on days when outdoor exercise isn’t possible.

Engaging these intelligent breeds with durable toys can provide mental stimulation and physical exercise, reducing the likelihood of destructive behaviors.

Grooming Requirements

Great Danes have short, smooth coats that are easy to maintain. Brush them weekly to remove loose hair and keep their coat shiny. They shed moderately year-round. Irish Wolfhounds have a wire-like double coat that needs more attention. Brush them 2-3 times a week to prevent matting. They shed seasonally.

Both breeds need:

  • Regular nail trims
  • Ear cleaning
  • Teeth brushing

Bathe these dogs as needed, usually every 4-8 weeks. Use dog-specific shampoos to protect their skin.

Diet Considerations

Both Great Danes and Irish Wolfhounds require diets that support their rapid growth and maintain their large frames. Providing fresh, human-grade dog food ensures they receive balanced nutrients essential for their health and vitality. Divide their daily portions into 2-3 meals to prevent bloat.

  • Great Danes need about 6-10 cups of food per day.
  • Irish Wolfhounds may need 4-8 cups. Adjust amounts based on age, weight, and activity level.
  • Avoid overfeeding to prevent obesity, which can strain their joints. 
  • Fresh water should always be available.
  • Consider adding supplements for joint health, especially as they age.

Ensuring your pet receives a balanced diet is crucial, and including a multivitamin can fill any nutritional gaps, helping maintain their overall health and vitality.

Training and Behavior Management

Start training early for both breeds. Use positive reinforcement techniques. Consistency is key. Great Danes and Irish Wolfhounds are intelligent and eager to please. Focus on:

  • Basic obedience commands
