About the Irish Terrier
The Irish Terrier is one of the oldest terrier breeds, developed in Ireland, with County Cork often credited, as an all-purpose farm dog for vermin control, guarding and even wildfowl retrieving. It earned lasting fame in the First World War as a messenger and sentry dog in the trenches, praised by handlers for its courage. Today it is far less common than its character deserves.
Irish Terriers were bred as all-round farm and guard dogs, and the breed standard's own description of heedless, reckless pluck sums them up well. They are fearless, spirited and fiercely loyal to their families, though that boldness means they're rarely a passive presence in the home. They want to be involved in whatever is going on.
With people they are typically warm and good-humoured, often described as comical and affectionate once past puppyhood. Their instincts for chasing, digging and guarding, and a tendency to be assertive with other dogs, mean early socialisation, consistent boundaries and regular structured exercise all matter. Early training also heads off food-guarding habits.
Common health conditions
Things Irish Terrier owners commonly watch for. Guidance, not veterinary advice.
Cystinuria
Irish Terriers carry a higher-than-average risk of this inherited stone-forming condition. Keep fresh water always available and discuss diet composition with your vet.
Digital hyperkeratosis (footpad thickening)
A hereditary hardening and cracking of the paw pads seen in the breed. Check the paws regularly, and ask breeders about DNA screening.
Hip dysplasia
Less common than in larger breeds but still reported. Keep a lean body condition through accurate portioning to reduce strain on the joints.
Skin allergies and irritation
Wiry-coated terriers can be prone to atopic skin issues. Feed a balanced fatty acid profile to support coat and skin alongside veterinary advice.
Feeding a Irish Terrier
Irish Terriers are small-to-medium, high-energy dogs, and a complete diet built for active breeds usually suits them well. It's easy to misjudge portions by eye, so weigh food against the pack guidelines. Adjust so the waist stays visible and the ribs stay easy to feel, as the breed gains weight quickly once exercise drops.
The breed's predisposition to cystinuria, an inherited condition that raises the risk of bladder and kidney stones, makes hydration worth extra attention. Keep fresh water constantly available, feed regular mealtimes rather than free-feeding, and discuss diet composition with a vet for any dog that has shown urinary symptoms. Two measured meals a day suit this breed better than one.

Common owner questions
How much should I feed an Irish Terrier?
Portion to the dog in front of you rather than a fixed amount. Most adults do well on two measured meals a day of a complete food for active breeds. Check body condition regularly and adjust for exercise and training treats, and our Food Finder can narrow down suitable options.
Are Irish Terriers prone to any particular health problems?
The main breed-specific concerns are cystinuria, which raises the risk of bladder and kidney stones, and digital hyperkeratosis affecting the footpads. Fresh water always available and a lean body condition both help, but take any suspected symptoms to a vet.
Do Irish Terriers get on with children and other dogs?
They're typically devoted and affectionate with their own family, including sensible older children, but the breed can be quick to resent interference from other dogs. Early socialisation and supervised introductions matter more here than with laid-back breeds.
How much grooming does an Irish Terrier need?
The harsh, wiry coat needs hand-stripping a couple of times a year to keep its texture and colour, plus a brush-through most weeks. Many owners use a professional groomer, since clipping alone softens the coat and its weatherproof qualities.
