History & Origin
The Irish Terrier originated in Ireland, where it was developed centuries ago as a versatile farm and hunting terrier capable of controlling vermin, guarding property, and assisting with small-game hunting. The breed is considered one of Ireland’s oldest terrier breeds and became highly valued for its courage, intelligence, and adaptability in rural communities throughout the country.
Irish farmers relied on the Irish Terrier to hunt rats, foxes, and other pests while also serving as a watchdog and loyal family companion. Unlike some terriers bred primarily for underground hunting, the Irish Terrier developed into a more versatile all-purpose working dog capable of handling a variety of farm tasks. Its athletic build, weather-resistant wiry coat, and strong prey drive helped it perform effectively in Ireland’s rugged countryside and changing climate.
The breed became especially admired for its fearless nature and willingness to protect both people and property. During World War I, Irish Terriers served as messenger dogs and sentries because of their bravery and ability to work reliably under difficult battlefield conditions. Their courage during wartime helped strengthen the breed’s reputation internationally.
Over time, the Irish Terrier also became appreciated as a devoted family companion known for loyalty, spirited personality, and deep attachment to its owners. Despite its fiery terrier nature, the breed developed a reputation for affection and companionship within the home.
Modern Irish Terriers still retain many characteristics shaped by centuries of farm and hunting work. Their intelligence, confidence, athleticism, and strong protective instincts reflect generations of selective breeding for versatility and resilience. Beneath the breed’s striking red coat and lively expression remains a courageous and highly spirited Irish working terrier deeply connected to Ireland’s rural history and traditions.

Grooming & Coat Care
The Irish Terrier has moderate grooming requirements due to its dense wiry coat and active outdoor lifestyle.
The harsh double coat should be brushed several times per week using slicker brushes, stripping combs, and grooming tools designed for wire-coated breeds to remove loose hair and prevent matting.
Many Irish Terriers benefit from regular hand-stripping or professional grooming to maintain proper coat texture and preserve the breed’s traditional harsh coat appearance.
The breed sheds relatively lightly compared to many other dogs, although dead hair must still be removed regularly through brushing or stripping.
Bathing is generally needed only periodically because the wiry coat naturally resists dirt relatively well. Overbathing should be avoided because it may soften the coat texture and reduce weather resistance.
Routine grooming should also include nail trimming, dental care, ear cleaning, and inspection of the skin and coat for irritation or debris.
The beard and facial furnishings may occasionally collect dirt or food particles and should be cleaned regularly to maintain hygiene and comfort.
Because the breed is highly active outdoors, owners should regularly inspect paw pads, nails, and skin following strenuous exercise or rough-terrain activity.
The weather-resistant coat provides good protection during outdoor activity while still allowing comfortable movement and flexibility.
Regular grooming sessions also provide valuable opportunities to monitor skin health, coat quality, and overall physical condition throughout life.

🐾 Lisa’s Picks for Irish Terriers
As someone who has worked with dogs for over 50 years—including more than 20 years helping with housebreaking and everyday care—I’m often asked for product recommendations. I’ve found that a few simple items can make a big difference in a dog’s comfort and daily routine.
If you have an Irish Terrier or are planning to bring one into your home, these products and tips can help support your journey together.
🛏️ 1. Dog Beds
👉 My Tip: Waterproof Bed Protection (My Personal Favorite Trick)
One thing I personally do is use twin-size waterproof mattress covers over larger dog beds. They’re easy to wash, protect the bed beneath, and save money long-term—especially helpful for puppies, seniors, or heavy shedders. You can find different colors and patterns that fit your decor.
For tiny dog beds, you can use waterproof pillow covers that fit over the beds to protect them and save money long-term.
I use the same idea around the house, too. Washable, waterproof couch covers are a simple way to protect furniture from dirt, shedding, and accidents—especially helpful with puppies, seniors, or dogs that love the couch.
* Orthopedic Foam Dog Beds:
A high-quality orthopedic bed is one of the best investments you can make for your dog. I recommend these for every breed, once they are out of the chewing stage, especially as they age. They provide joint support, improve comfort, and help dogs truly rest.
* Tough Dog Beds for Dogs That Chew:
If your dog tends to chew or destroy their bedding, a standard plush bed may not last long. In these cases, I recommend tough, chew-resistant dog beds made with reinforced materials.
These are designed to hold up better against digging, scratching, and chewing, and can save you from constantly replacing beds. While no bed is completely indestructible, choosing a more durable option can make a big difference.
* Puppies need Simple Washable Bedding:
For young puppies that are still learning house training, I often suggest starting with simple, washable blankets instead of an expensive dog bed.
Thick towels, fleece throws, or washable pads work very well during this stage. They’re easy to clean, quick to replace, and help protect your main dog beds until your puppy is more reliable. Once house training is more consistent, you can transition to a more permanent, supportive bed.
✂️ 2. Proper Grooming Tools for the Irish Terrier Coat
Irish Terriers have a dense, wiry coat with a softer undercoat, so using the right grooming tools makes a big difference.
A gentle slicker brush works well for regular brushing to remove loose hair and keep the coat tidy, while a metal comb helps with detail work around the beard, legs, and furnishings where tangles may develop. Occasional hand-stripping is often recommended to help maintain the coat’s proper harsh texture and rich color, although clipping may be used for easier maintenance in pet homes.
Regular grooming helps keep the coat healthy, neat, and true to the breed’s classic terrier appearance.
Regular brushing:
- Helps remove loose hair
- Maintains coat texture
- Keeps the coat healthy
🦴 3. Treats (Great for All Dogs)
- Jerky Treats for Dogs: Almost all dogs love soft, easy-to-break NATURAL jerky treats. They’re perfect for rewarding good behavior without overfeeding. Soft jerky treats provide protein and are easy to chew.
- Tiny Treats for Small Dogs
For small dogs, I recommend using very tiny, NATURAL training treats that are soft and easy to chew. This lets you reward often without overfeeding.
- Stronger Chew Treats for Larger Dogs
Dogs that enjoy a more robust chewing experience will benefit from stronger chew treats. Some larger dogs may still go through them quickly, while others will take more time—so it often depends on the individual dog.
👉 My Tip: Check Ingredient Labels
I always recommend checking the ingredient label when choosing treats at the store. Dogs don’t need added sugar or artificial ingredients, and some treats can upset their stomach or cause diarrhea. Look for all-natural ingredient labels, and single ingredient or few ingredient labels are preferred.
It’s important to note that even among the same breed, some dogs enjoy chewing more than others, and many have preferences for certain types of chews. If you notice bleeding gums during chewing, it’s a good idea to have your dog examined by a veterinarian to rule out any dental issues.
🧠 4. Enrichment Toys for Mental Stimulation
Irish Terriers are active, so giving them something to do is important.
An enrichment toy can help:
- Prevent boredom
- Reduce unwanted behaviors
- Keep their mind engaged
When choosing an enrichment toy, think about your dog’s personality and needs. Some dogs love puzzle toys and mental challenges, while others are happier with something they can chew or carry around.
🐕 5. Safe, Comfortable Harness, Collar & Leash
From my experience, choosing the right walking gear can make a big difference in both safety and control. Some harnesses and collars are designed to help prevent dogs from slipping out, which is especially important for strong or easily startled dogs, and those are the types I personally recommend for safety.
Harness: A quality, comfortable properly fitted harness can make walks more comfortable and easier to manage—especially for dogs that tend to pull or get excited outdoors. If you have a dog that tries to wiggle out of their harness, search for an “escape proof” harness that has an extra strap towards the back.
Collar: I use and prefer safety martingale collars, as they can help prevent dogs from backing out of their collar while still being more gentle than traditional collars when used correctly.
Leash: Choose a lightweight leash for small dogs and a sturdier, heavier leash for larger dogs to ensure good control. Nylon leashes are strong and long-lasting. Some leashes also include a comfortable padded handle.
👉 My Tip: Avoid Retractable Leashes
I don’t recommend retractable leashes, as they can break and tangle easily and create safety issues and tripping hazards.
💡 Lisa’s Tip:
You don’t need a lot of products to care for a dog well… just the right ones. Focus on comfort, consistency, and routine, and you’ll make life easier for both you and your dog.
