Irish Setter
An in-depth look at the Irish Setter, covering its history, distinct red coat, temperament, and the split between show and field lines.
11 to 12 years is the typical life expectancy for an Irish Setter, though a 2024 UK study suggests the average may now be closer to 12.9 years. This number varies significantly depending on whether the dog comes from show lines or working field lines, as the latter tend to be smaller and leaner.
Appearance and physical standards
The breed is defined by a coat that is moderately long, silky, and exclusively red or chestnut in colour, with an abundant undercoat in winter. Males typically stand 24 to 28 inches tall and weigh between 65 and 75 pounds, while females are slightly smaller at 21.5 to 24.5 inches and 55 to 65 pounds. The FCI Breed Standard allows for slightly different measurements, with males up to 26.5 inches and females up to 24.5 inches. Their deep chests and small waists are characteristic, and the coat requires frequent brushing to prevent matting, with feathering present on the tail, ears, chest, legs, and body.
Temperament and daily needs
Irish Setters are demonstrably affectionate, gentle, and highly active dogs that require long daily walks and off-lead running in wide, open spaces. Their energy levels are high enough that they are widely used as therapy dogs in schools and hospitals, where they help create a calming environment for patients and students. Without sufficient physical exercise and mental stimulation, this breed can become restless, as their history as tireless, wide-ranging hunters demands a job to do.
History and the split between lines
The breed's history traces back to early references in Caius's De Canibus Britannicis from 1570, though the solid red colour seen today is the result of selective breeding practices that took centuries to solidify. The modern breed standard was first drawn up by the Irish Red Setter Club in Dublin in 1886, establishing a 100-point scale that remains largely unchanged. A significant divergence occurred in the late 19th and 20th centuries when show enthusiasts preferred the solid red coat, while field trialers sought to maintain hunting abilities, leading to the creation of the distinct Working Red Setter.
Show dogs versus working Red Setters
Show-bred Irish Setters are generally larger, heavier, and possess a more silky coat with longer feathering, whereas the modern Working Red Setter is smaller, weighing around 45 pounds compared to the show dog's 70 pounds. The working variety often displays a lighter russet or fawn colour and may have patches of white on the face and chest, traits that were more common in the breed's earlier iterations. This split was formalized in 1975 when the American Kennel Club denied reciprocal registration with the Field Dog Stud Book, effectively separating the two lines for competitive purposes.
Health and genetic considerations
While the breed generally enjoys a robust lifespan, Irish Setters are predisposed to specific genetic conditions that owners must monitor. Gluten intolerance is a naturally occurring genetic disorder affecting the small intestine, causing malnutrition and diarrhea if the dog consumes gluten, though a gluten-free diet can prevent these effects. The breed is also prone to atopic dermatitis, a skin condition that requires management. Prospective owners should be aware that while the breed is generally healthy, these specific vulnerabilities require proactive care and dietary awareness.
