A Wheaten puppy rarely resembles the adult. The FCI standard says puppies are born reddish, greyish and only sometimes pure wheaten, usually with a black mask. The final coat emerges after several colour and texture changes, usually between 18 months and two and a half years.

The smallholder’s terrier
Wheaten terriers helped Irish smallholders kill vermin and work on farms, also hunting badgers and otters for many years. The standard considers the Wheaten probably the oldest of four Irish terriers, citing soft-coated dogs from at least 200 years ago. Official Irish Kennel Club recognition came only in 1937. Closest relatives in the encyclopedia include the Kerry Blue Terrier, Irish Terrier and Irish Glen of Imaal Terrier.
Warm-hearted but no shrinking violet
Spirited and determined, good-natured and deeply devoted to their person, highly intelligent and ready to defend without aggression: the standard’s description. Many Wheatens greet people exuberantly, so teach calm greetings early and kindly.
Silky hair without undercoat
The coat has no undercoat, permitted only on the ears. It mats quickly without thorough combing down to the skin several times weekly. Trimmed dogs have short body, neck and skull hair, retaining long hair above eyes and on chin. Untrimmed hair must not exceed 12.7 cm or stand off like a Poodle’s. The standard describes docking to two-thirds but explicitly permits a natural tail. In Germany, docking is generally prohibited under Section 6 of the German Animal Welfare Act.
Exercise with thought
A powerful medium-sized dog wants daily movement, sniffing and thinking. Retrieving games, tracking or calmly paced agility suit well.
Protein loss through gut and kidneys
With a median of 13.7 years, Wheatens lived longer than crossbreeds in McMillan and colleagues’ analysis. However, familial protein loss through the gut (PLE) or kidneys (PLN) is documented. Littman and colleagues analysed 222 affected dogs: PLE became apparent at a mean 4.7 years, PLN at 6.3. Typical signs were vomiting, diarrhoea, weight loss and fluid in abdomen or chest, with poor prognosis. Regular blood and urine checks from middle age detect changes early. Swiss cancer-registry tumour rates were 1,724 per 100,000 dog-years versus 581 for crossbreeds, mostly benign (Dhein et al. 2024).
Who a Wheaten suits
People wanting an affectionate, playful medium-sized dog, treating grooming as a regular appointment and accepting preventive examinations.
Who should look elsewhere
Anyone wanting low maintenance with little time, unwilling to train against jumping on visitors or needing a tight veterinary budget.
Find out whether a Wheaten fits your life with the breed quiz; our book “Which Dog REALLY Suits You?” (book in German) offers detailed help. For early puppyhood, there is the free Puppy Starter Pack. The wheaten colour works well on a magazine-cover canvas or as a poster in a wooden frame.
