The Irish Terrier is a medium-sized member of the Terrier Group, standing about 16 to 18 inches tall and weighing roughly 25 to 27 pounds. Bred in Ireland and recognized in 1885, it is sometimes called the Red Daredevil, a nod to its bright red coat and fearless streak.
The breed wears a dense, wiry double coat of medium length. The broken outer jacket hugs the body and resists water, while a softer undercoat helps hold in warmth on cool, damp days.
In temperament the Irish Terrier is bold and dashing yet tenderhearted with the people it loves. Curious, alert, and loyal, it makes a watchful companion and a devoted family member, with a fiery personality that matches its coat.

Care
The routines that matter most for this breed. Open one at a time.
Nutrition
Feed your Irish Terrier a complete, balanced food matched to its life stage and activity level, and keep fresh water available at all times. Packaging on complete, balanced foods includes a feeding chart based on your dog's ideal weight, and how much to feed depends on age, size, activity, and health, so your veterinarian is the best resource for an exact amount.
Puppies need three to four meals a day. Full-grown Irish Terriers do well on two or three meals daily to hold a steady energy level.
Watch the calories, since all dogs can gain weight if they take in too many. Trim portions if your pup puts on weight, and remember that too many treats on top of regular meals add up. Some human foods are safe for dogs and some are not, so learn the difference and check with your veterinarian about your dog's weight or diet.
A complete, balanced diet supplies all the nutrients an Irish Terrier needs. Beyond that, omega-3 fatty acids can support skin and coat health and glucosamine can support joint health. Always talk with your veterinarian before starting any new supplement.
Grooming
The Irish Terrier's wiry double coat needs regular care to stay in good shape. To keep the red coat's texture and bright color, hand-strip it twice a year rather than clipping, a process that removes hair at the root instead of trimming it. Brush at least once a week to clear out dirt, debris, and loose hair.
Irish Terriers tend to be low shedders, though they are not a hypoallergenic breed. They do not typically have sensitive skin, but watch for changes such as redness, flakiness, or lumps and bumps, and keep up regular veterinary checkups.
Trim the nails regularly, since overly long nails cause discomfort and trouble walking. Clean the ears routinely with a veterinary-approved cleanser to limit wax buildup, and contact your veterinarian if you notice redness or odor. Wipe the eyes with a veterinary-approved wipe to help prevent tear stains, and reach out to your vet about changes such as discharge or cloudiness.
Exercise
The Irish Terrier is lively, playful, and outgoing, with energy to spare. Plan on at least 60 to 90 minutes of exercise every day. A securely fenced yard is ideal; without one, this breed needs several leashed walks a day to stay physically and mentally fit.
These are capable athletes that shine in dog sports. Obedience, agility, rally, earthdog, and flyball give an outlet for their energy and intelligence, and field trials, hunting, and tracking suit them too.
Irish Terriers are talented escape artists who will jump or dig to get out, especially if they spot something to chase, so keep that fence secure. Curious and alert, they may bark to flag strangers or unusual activity, but they are not excessive barkers. Plenty of physical and mental stimulation helps head off destructive behavior.
Training
The Irish Terrier is smart and eager to please, but also strong-willed and independent, the way terriers tend to be, and that streak can make training a challenge. Start positive reinforcement the day you bring your puppy home, using toys and treats as motivation, and set firm, consistent boundaries.
Early, consistent socialization and basic obedience help your dog grow into a well-mannered adult who is comfortable with family and friends. This is a quick learner that adapts well to new situations, and reinforcing those early lessons works best as a lifelong habit.
Irish Terriers love being part of family activities, and their energy meshes well with children who understand appropriate play. Supervise all interactions between children and dogs.
This breed may prefer to be the only dog in the home. Bred to hunt small animals such as rodents and foxes, Irish Terriers may view cats, small pets, and neighborhood wildlife as something to chase, so keep your dog leashed or in a fenced space outdoors to keep everyone safe.
