Irish Terrier
A fiery red working terrier, devoted and affectionate with its family but famously combative with other dogs. Bold, spirited and brave, needing firm, consistent handling.

Irish Terrier scorecard
Overview
The Irish Terrier is a spirited, fiery-coated working terrier, instantly recognisable by its rich red, wiry coat, long head and bold, dashing carriage. Devoted and affectionate with its own family, it is famous for its courage and its readiness to take on any challenge, earning it the old nickname "daredevil".
A medium-sized dog of around 46–48 cm and roughly 11–12 kg, it is racy and athletic rather than stocky. It makes a loyal and entertaining companion for an experienced, active owner, but its strong character and tendency to be combative with other dogs mean it needs firm, consistent handling.
Good to know — a Irish Terrier is best with a garden and manageable for committed beginners. Every dog is an individual, so meet a few and chat to a good breeder or rescue before deciding.

History & origins
The Irish Terrier is one of the oldest terrier breeds, with type established in Ireland during the 19th century, where it was an all-purpose farm dog used for ratting, hunting vermin and guarding. It was among the first terrier breeds recognised by the Kennel Club, with classes appearing in the late 1870s.
The breed earned particular renown during the First World War, when Irish Terriers served as messenger and sentry dogs and were praised for their courage and reliability under fire. Today it is recognised by the UK Kennel Club in the Terrier group and by the FCI, and although no longer common, it retains a devoted following.
Temperament & family fit
Irish Terriers are bold, lively and intensely loyal to their families, often forming a particularly strong attachment to one or two people. They are affectionate and playful at home, typically good with the children of their own household, and they have a reputation for bravery that borders on recklessness.
The flip side of this courage is a famous dislike of other dogs: the breed can be quarrelsome and is often best as the only dog in the home, particularly with dogs of the same sex. A strong prey drive means small pets are also at risk. Early, thorough socialisation helps, but the underlying terrier feistiness should be expected rather than trained away entirely.
- Families with children of all ages
- Owners ready for consistent training
- Homes with a secure garden
Training & intelligence
Intelligent and quick-witted, the Irish Terrier learns readily but has an independent, sometimes stubborn streak that calls for firm, fair and consistent training. It is not the ideal choice for a complete novice unless that owner is prepared to be patient and assertive.
Reward-based methods work well, but the dog needs a handler who sets clear boundaries and maintains them. Recall and impulse control deserve particular attention given the breed's prey drive and willingness to scrap. Mental engagement and a sense of purpose keep this clever terrier out of mischief.
- Start socialisation & handling early
- Reward-based methods only — no harsh corrections
- Channel energy into training games & enrichment
Exercise needs
A healthy adult Irish Terrier typically needs 90 minutes to 2 hours a day (roughly 90–120 minutes), split across walks, play and a little training. Higher-energy dogs also need their brains tired — sniffy walks, training games and puzzle feeding go a long way. Puppies, seniors and dogs with health conditions need adjusted amounts — check with your vet.
Grooming & coat
The harsh, wiry double coat is low-shedding and benefits from regular brushing to keep it tidy. To maintain the correct texture and colour, the coat is traditionally hand-stripped a couple of times a year rather than clipped; clipping softens the coat and dulls the colour. Otherwise grooming is straightforward, with routine nail trimming, ear checks and dental care.
- Brush several times a week
- Bathe every few weeks or as needed
- Check ears, nails and teeth weekly
Feeding a Irish Terrier
Feed a complete, good-quality diet suited to the dog's age and active lifestyle, divided into two meals daily. Irish Terriers are not prone to obesity if well exercised, but portions should still be matched to body condition. Provide constant access to fresh water and avoid heavy exercise immediately around mealtimes.
A medium breed
An adult Irish Terrier typically weighs 11–12 kg, so a healthy Irish Terrier eats a moderate amount compared with other breeds. Every feeding guide on a bag is written per kilo of body weight, not per breed — start there, then adjust to the dog in front of you.
Life stage
A medium breed is usually done growing at ~12 months, which is roughly when a puppy food has finished its job. With a typical lifespan of 12–15 years, there is a long adult stretch in the middle; switch to a senior food when your vet thinks it is worth it rather than on a birthday.
A high-energy dog eats like one
Irish Terriers sit at the top end for energy, and a dog working through an hour and a half of real exercise a day burns through the feeding guide faster than a dog on a short stroll. Feed to the dog's condition, not to the middle of the range on the bag.
How much should a Irish Terrier weigh?
Adult 11–12 kgfully grown at ~12 months
| Age | Stage | Typical weight | Of adult size |
|---|---|---|---|
| 8 weeks | Just home | 1.7–1.8 kg | 15% |
| 3 months | Young puppy | 2.8–3 kg | 25% |
| 6 months | Growing fast | 5.5–6 kg | 50% |
| ~12 months | Fully grown | 11–12 kg | 100% |
A guide, from the same rule of thumb our puppy growth predictor uses — each age is that share of the way to maturity for a medium breed. Puppies grow fastest early, so a real puppy usually sits a little above the middle rows. Weigh yours and ask your vet if the number worries you.

The Irish Terrier is generally a tough, healthy and long-lived breed, with relatively few widespread inherited problems compared with many pedigree dogs. Its working heritage and robust constitution contribute to its reputation for hardiness.
Nonetheless, responsible breeders screen for the conditions known in the breed, and prospective owners should buy from health-conscious breeders following UK Kennel Club guidance. Maintaining a healthy weight, good dental care and routine veterinary checks supports a typical lifespan of around 12–15 years.
Common health conditions to be aware of
- Hyperkeratosis (corny feet) — a hereditary condition causing thickened, hardened footpads, recognised in the breed; DNA testing is available.
- Hip dysplasia — a developmental joint condition; breeding stock should be hip-scored.
- Hypothyroidism — an underactive thyroid that can affect coat, weight and energy, manageable with medication.
- Cystinuria — a hereditary condition that can cause urinary stones in some terriers.
- Cataracts — occasionally reported; periodic eye checks of breeding dogs are sensible.
These reflect typical, size- and coat-related risks for dogs like the Irish Terrier; individual breeds carry their own predispositions. Always buy from health-tested parents and speak to your vet — this isn't a diagnosis.
Protect against surprise bills

Bringing home a Irish Terrier puppy
Puppies need controlled exercise (a rough guide is five minutes per month of age, twice a day) to protect growing joints, little-and-often meals of a complete puppy food, early socialisation, and a calm routine for toilet training and sleep. Book first vaccinations, microchipping and a vet check early.
New puppy checklist →Caring for a senior Irish Terrier
As they age, watch weight, joints and teeth, switch to a senior diet if your vet advises, keep exercise gentle but regular, and consider orthopaedic bedding and ramps. Twice-yearly vet checks help catch issues early.

Frequently asked questions
What is the Irish Terrier's temperament like?
Irish Terriers are bold, lively and intensely loyal, often forming a particularly strong attachment to one or two people. They are affectionate and playful at home and typically good with the children of their own household. Famous for courage that borders on recklessness, they earned the old nickname "daredevil", and they make entertaining companions for active owners.
Are Irish Terriers good with other dogs?
Often not. The breed has a famous dislike of other dogs and can be quarrelsome, so it is frequently best as the only dog in the home, particularly with dogs of the same sex. A strong prey drive also puts small pets at risk. Early, thorough socialisation helps, but this terrier feistiness should be expected and managed rather than trained away entirely.
Are Irish Terriers suitable for first-time owners?
Not ideally. They are intelligent and learn readily, but have an independent, sometimes stubborn streak that calls for firm, fair and consistent handling. A novice can succeed only if prepared to be patient and assertive and to set clear boundaries. Recall and impulse control deserve particular attention given the breed's prey drive and willingness to scrap.
How should an Irish Terrier's coat be groomed?
The harsh, wiry double coat is low-shedding and needs regular brushing to stay tidy. To maintain the correct texture and rich colour, it is traditionally hand-stripped a couple of times a year rather than clipped, as clipping softens the coat and dulls the colour. Otherwise grooming is straightforward, with routine nail trimming, ear checks and dental care.
How much exercise does an Irish Terrier need?
This energetic, athletic breed needs a good hour or more of daily exercise, including brisk walks, play and the chance to use both body and mind. A securely fenced garden is valuable, as Irish Terriers are agile and can be determined escapers. A well-exercised Irish Terrier is far easier to live with than a bored one.
How big are Irish Terriers?
They are medium-sized terriers, standing around 46–48 cm and weighing roughly 11–12 kg. The build is racy and athletic rather than stocky, topped by the breed's distinctive rich red, wiry coat, long head and bold, dashing carriage.
Are Irish Terriers a healthy breed, and how long do they live?
The Irish Terrier is generally tough, healthy and long-lived, with relatively few widespread inherited problems compared with many pedigree dogs, thanks to its working heritage and robust constitution. Even so, responsible breeders screen for conditions known in the breed. Good weight management, dental care and routine checks support a typical lifespan of around 12–15 years.
Are Irish Terriers good with children?
Good with children. As a general guide, Irish Terriers tend to be patient and tolerant. Whatever the breed, always supervise dogs and young children and teach kids to interact gently.
How much exercise does an Irish Terrier need?
As a healthy adult, a typical Irish Terrier needs 90 minutes to 2 hours of exercise a day (90–120 minutes), split across walks plus play. Higher-energy dogs also need mental stimulation — sniffing, training games and puzzle feeders — to stay settled. Puppies, seniors and dogs with health conditions need less — ask your vet.
Do Irish Terriers shed a lot?
Low shedding. Coat upkeep is regular brushing — brush regularly to keep the coat in good condition.
Are Irish Terriers easy to train and good for first-time owners?
Manageable for committed beginners. Irish Terriers are best for owners ready to commit to consistent training and plenty of activity. Reward-based training and early socialisation help any dog.
Do Irish Terriers bark a lot?
Moderate barker. They are usually fairly easy-going about barking, though any dog will bark if bored or under-exercised.
Are Irish Terriers good with other dogs?
Can be selective with other dogs. Early, positive socialisation with other dogs from a young age makes a big difference.
Do Irish Terriers suit flats or smaller homes?
Best with a garden. A Irish Terrier is happiest with access to a secure garden and regular outdoor exercise.
