Irish Terrier Dog Breed: The Red Devil That Served in World War I
The Irish Terrier is a courageous, red-coated dog with a working history that includes carrying messages across battlefields during World War I. Often associated with the nickname “Red Devil,” this lively breed has earned its reputation for boldness, determination, and an unmistakable terrier personality.
But what is an Irish Terrier really like at home? These medium-sized dogs can be affectionate, entertaining companions, although their independence and occasional friction with other dogs deserve serious consideration.
Understanding their temperament, exercise needs, grooming routine, and potential health problems will help you decide whether this Irish breed belongs in your household.

History and Origin of the Irish Terrier
The Irish Terrier is one of Ireland’s oldest native terrier breeds. Its early ancestors were working dogs valued for their ability to hunt vermin, guard property, and assist with everyday farm tasks.
Early Irish Terriers appeared in several coat colors, including black and tan, gray, and brindle. The solid red coat became the breed’s defining feature through selective breeding during the nineteenth century.
The breed entered the show ring in the late nineteenth century and gained recognition as a distinct pedigree breed. The American Kennel Club formally recognized the Irish Terrier in 1885.
Why Is the Irish Terrier Called the Red Devil?
The nickname “Red Devil” reflects the breed’s fiery appearance and fearless reputation. The American Kennel Club also describes the Irish Terrier as the “Daredevil” of the Emerald Isle.
That reputation has a practical explanation. Irish Terriers were developed to tackle demanding work without backing down easily, even when facing animals larger than themselves.
During World War I, the breed served as a messenger and sentry dog. These dogs carried communications across dangerous ground and helped military personnel maintain contact when other methods were unreliable.
Their wartime service strengthened a reputation for courage that had existed long before the conflict.
However, the nickname can give the wrong impression to someone unfamiliar with the breed. Irish Terriers are not automatically aggressive toward people. Their boldness is more closely associated with their working instincts, independence, and willingness to confront challenges.
For a closer look at the breed’s historical background, the American Kennel Club’s Irish Terrier profile provides additional information.
Physical Characteristics of the Irish Terrier
The Irish Terrier has an athletic, streamlined build that reflects its history as a working dog. Its body combines strength with agility, allowing it to move quickly without appearing heavy or cumbersome.
Size and Weight
Adult males typically stand around 19 inches at the shoulder, while females stand approximately 18 inches.
A typical adult weighs about 24–27 pounds, although individual dogs may fall outside this range.
The breed should look athletic and balanced. Excess weight can make exercise harder and place additional strain on the joints, so maintaining an appropriate body condition matters throughout adulthood.
Coat and Color
The Irish Terrier’s coat is one of its most recognizable features.
It has a harsh, wiry outer layer and a softer undercoat that provides insulation. This combination helps protect the dog from damp and cool conditions.
Accepted colors include red, red-wheaten, and yellow-red shades. Small amounts of white on the chest may be acceptable under the British breed standard.
Regular coat care helps preserve the coat’s texture and appearance. Clipping can alter the texture of a wiry coat, so owners should learn about hand-stripping before deciding on a grooming routine.
Facial Features and Overall Appearance
The breed typically has a long head, small V-shaped ears, and dark eyes. Its facial hair gives it a distinctive terrier expression without creating the heavy furnishings associated with some other wire-coated breeds.
Its appearance is striking, but prospective owners should pay at least as much attention to temperament and health as they do to coat color.
Irish Terrier Temperament and Personality
The Irish Terrier is energetic, confident, and strongly attached to its family. Many are playful companions that enjoy participating in everyday household activities.
Their working background also means they can be independent. An Irish Terrier may understand a command perfectly well and still need a convincing reason to respond.
Are Irish Terriers Good Family Dogs?
They can be excellent family companions when their needs are understood and their behavior is managed consistently.
Irish Terriers are generally known for their affectionate nature toward people. They can form close bonds with their owners and enjoy active play, training sessions, and outdoor adventures.
However, individual temperament matters more than a breed description alone.
Families should consider whether they can provide enough exercise, supervision, and consistent training. Children also need to learn how to interact respectfully with dogs, and an adult should supervise interactions with young children.
An Irish Terrier that receives suitable exercise and guidance may settle comfortably at home after an active day. One that becomes bored or frustrated may find its own entertainment, and that is not always the kind of entertainment an owner appreciates.
Do Irish Terriers Get Along With Other Dogs?
This is one of the most important considerations when choosing the breed.
Irish Terriers can be quick to react to interference or challenges from unfamiliar dogs. Their confident nature may lead them into confrontations they could have avoided.
Early socialization helps puppies learn to encounter other dogs calmly. Reward-based training also gives owners practical ways to redirect attention and reinforce appropriate behavior.
Keep these precautions in mind:
- Introduce unfamiliar dogs gradually in controlled settings.
- Use a secure leash in public spaces where encounters could become difficult.
- Avoid forcing interactions when either dog appears uncomfortable.
- Choose off-leash areas carefully, considering the dog’s history and recall reliability.
- Seek help from a qualified, reward-based trainer if reactivity or aggression develops.
Living with another dog may be possible, but compatibility should be assessed individually. Two dogs should never be expected to get along simply because they share a household.
Are Irish Terriers Easy to Train?
Irish Terriers are intelligent and capable learners, but their independent streak can make training challenging.
Short sessions with clear rewards tend to work better than repeated commands or harsh corrections. Food rewards, toys, praise, and opportunities to explore can all help maintain engagement.
Start with the basics:
- Teach a reliable response to the dog’s name.
- Practice recall in secure, low-distraction areas before increasing difficulty.
- Reward calm behavior around unfamiliar dogs.
- Teach loose-leash walking and polite greetings.
- Introduce handling for grooming, nail care, and veterinary examinations.
Give it time. Consistency matters more than expecting perfect behavior after a few sessions.

Irish Terrier Care Guide
Irish Terriers need a balanced routine that includes appropriate nutrition, daily activity, coat maintenance, and preventive veterinary care.
Diet and Nutrition
Feed your Irish Terrier a complete and balanced dog food appropriate for its life stage, body condition, and activity level.
Puppies have different nutritional requirements from adults, while senior dogs may need adjustments based on their health and activity. Your veterinarian can help you choose a suitable diet if your dog has specific nutritional needs.
A few everyday habits make feeding easier to manage:
- Follow the food manufacturer’s feeding guidance as a starting point.
- Divide the daily ration into suitable meals, commonly two meals for adults.
- Measure portions rather than estimating them by eye.
- Include treats in the overall daily calorie allowance.
- Keep fresh drinking water available at all times.
- Check body condition regularly and adjust portions when necessary.
The ideal amount of food depends on the individual dog. A highly active terrier may need more energy than a less active dog of the same weight.
Exercise Requirements
Plan for approximately one hour of daily exercise as a starting point for a healthy adult Irish Terrier.
Some individuals will need more activity, particularly if they enjoy running, scent games, or structured training. Puppies require age-appropriate activity that avoids excessive repetitive impact while their bodies develop.
A useful daily routine might include:
- Morning: A brisk walk with opportunities to sniff and explore.
- Afternoon: A short training session or an interactive game that exercises the dog’s mind.
- Evening: Another walk, playtime, or an activity suited to the dog’s fitness and behavior.
Mental stimulation deserves attention alongside physical exercise. Food puzzles, scent games, and reward-based training can help an intelligent terrier stay occupied.
Because some Irish Terriers react strongly to unfamiliar dogs, choose exercise locations carefully. A quiet walking route or secure private garden may be more suitable than a crowded dog park.
Grooming Needs
The Irish Terrier has a relatively low-maintenance coat in terms of everyday brushing, but preserving its proper texture requires more than an occasional bath.
Brush the coat a couple of times per week to remove loose hair and debris. Check the beard, legs, and other areas where dirt can collect.
Hand-stripping removes dead outer-coat hairs and helps maintain the coat’s characteristic wiry texture. Many owners arrange professional stripping two or three times a year, although the appropriate schedule depends on the coat and grooming goals.
Regular clipping may soften the coat’s texture over time. If you want to maintain the traditional appearance, ask a groomer experienced with wire-coated terriers to demonstrate the correct technique.
Routine grooming should also include nail checks, ear inspections, and dental care.
Introduce these activities gradually, rewarding calm cooperation. Starting when a dog is young usually makes the process easier.
Irish Terrier Health Problems
Irish Terriers are generally robust dogs, but no breed is free from inherited health concerns.
Two conditions deserve particular attention when researching a puppy or reviewing an adult dog’s medical history.
Hereditary Footpad Hyperkeratosis
Hyperkeratosis affects the development of the skin on the footpads. The pads may become unusually thick, hard, and cracked.
Affected dogs can experience discomfort, and damaged pads may interfere with normal walking.
A genetic test is available for hereditary footpad hyperkeratosis. Prospective owners should ask breeders about testing and the health history of the puppy’s relatives.
If your Irish Terrier develops painful cracks, thickened pads, or difficulty walking, arrange a veterinary examination rather than attempting to diagnose the condition at home.
Cystinuria and Bladder Stones
Cystinuria is an inherited condition that affects how the body handles certain amino acids. In affected dogs, this can lead to cystine crystals and bladder stones.
Possible warning signs include difficulty urinating, frequent attempts to urinate, blood in the urine, or signs of discomfort.
Difficulty passing urine or an inability to urinate requires urgent veterinary attention. A urinary blockage can become life-threatening.
There is no single universal screening approach suitable for every dog, so discuss the parents’ medical history and any recommended testing with the breeder and your veterinarian.
General Preventive Care
Responsible care involves more than monitoring breed-specific conditions.
Keep up with routine veterinary examinations, vaccinations, parasite prevention, dental care, and weight management. Your veterinarian can also recommend age-appropriate screening based on your dog’s family history and individual health.

Irish Terrier Puppies: Buying or Adopting Responsibly
If you are searching for an Irish Terrier puppy, take your time choosing a breeder. Availability and price alone tell you very little about the quality of a dog’s early care.
Ask about the parents’ temperaments, health history, and any recommended genetic testing. A responsible breeder should be willing to explain how puppies are raised and what support is available after they leave.
Before committing, consider these questions:
- Can I meet the puppy’s mother and see where the puppies are raised?
- What veterinary examinations, vaccinations, and preventive treatments have been provided?
- Have the parents undergone appropriate health screening?
- How have the puppies been introduced to people and ordinary household experiences?
- What documentation will accompany the puppy?
- Will the breeder offer guidance if questions arise after the puppy comes home?
Be cautious of sellers who refuse reasonable questions or pressure you to pay immediately.
How Much Does an Irish Terrier Cost?
The price of an Irish Terrier varies by country, breeder, pedigree, health testing, and local availability. There is no single figure that accurately represents every market.
Remember to budget for more than the initial purchase. Food, grooming, training, routine veterinary care, preventive treatments, equipment, and unexpected medical expenses all contribute to the lifetime cost of ownership.
Adoption may also be worth considering. Contact reputable rescue organizations and shelters, and ask whether an Irish Terrier or a suitable terrier cross is available.
The most important decision is finding a dog whose needs and temperament fit your household, regardless of whether you buy or adopt.
Is the Irish Terrier the Right Companion for You?
The Irish Terrier can be a rewarding companion for an active person or family that enjoys spending time outdoors and is prepared to provide consistent training.
This breed may suit you if you:
- Want an energetic dog that enjoys walks and interactive play.
- Appreciate an independent, spirited personality.
- Can commit to regular training and mental enrichment.
- Are comfortable managing introductions to unfamiliar dogs.
- Can maintain a consistent grooming routine.
You may want to consider another breed if you need a dog that is naturally relaxed around every unfamiliar dog or requires very little daily activity.
The Irish Terrier’s courage and determination are part of its appeal, but they also come with responsibilities. Choose based on the dog’s everyday needs, not just its remarkable history or distinctive red coat.
