Irish Setter Growth Chart
The Irish Setter is an elegant, athletic red gun dog bred for ranging across open fields. Puppies grow tall quickly and look lanky for months before muscle and coat fill in, reaching full maturity around 14 to 18 months. Expect a lean, leggy phase in the middle months — that is normal for the breed.

breeds.irish-setter Growth Stages
Understanding the typical growth stages helps you know what to expect as your breeds.irish-setter puppy grows.
Neonatal
0–2 weeksPuppies are born with eyes and ears closed, relying entirely on their mother. Rapid weight gain occurs during this period.
Socialization
3–12 weeksEyes and ears open. Puppies begin to explore, play, and learn social behaviors. This is a critical period for development.
Juvenile
3–8 monthsRapid growth continues. Puppies become more independent, start teething, and develop coordination.
Adolescent
8–14 monthsGrowth rate begins to slow. Puppies reach sexual maturity and may test boundaries. Muscle mass develops.
Young Adult
14–18 monthsGrowth is nearly complete. Your puppy is filling out and approaching adult proportions.
Adult
18+ monthsYour puppy has reached their full adult size. Weight should remain relatively stable with proper nutrition.
breeds.irish-setter FAQ
How much will my Irish Setter puppy weigh as an adult?
Irish Setters typically reach 60 to 70 pounds as adults, with males usually a touch heavier and taller than females. Field-bred lines often run leaner and lighter than show lines. A lanky teenager that looks light for its height usually fills out by the second year.
At what age is a Irish Setter fully grown?
Most Irish Setters reach adult weight around 14 to 18 months. Height comes early and weight follows later, so a 10-month-old may look nearly done while still gaining muscle and coat. Females often finish a little sooner than males.
How accurate is a Irish Setter puppy weight chart?
Fairly accurate, with bloodline as the main variable: field lines bred for hunting tend to be lighter and racier than bench lines. Irish Setters also vary in how long they stay lanky, so two puppies the same age can look quite different yet both be on track. Consistent weekly gains matter more than matching any single number.
How much should a Irish Setter puppy weigh at 12 weeks?
Check the 12-week row in the weight-by-age table above for the estimated male and female ranges. If your puppy falls well outside that band, re-check the scale, the lb/kg setting, and the age entry first — a single off reading is more common than a truly unusual puppy.
Do male and female Irish Setters grow differently?
Males are usually slightly taller and heavier, often landing toward the top of the 60 to 70 pound range, while females trend a bit lighter. Females also tend to mature a little earlier. The difference is modest and both follow the same overall curve.
