What each stage means for a Irish Setter

Young adult (1–3): still learning. Keep training consistent and set the healthy weight now; for a Irish Setter that is usually within 60–70 lb.
Mature adult (3–9): yearly checkups, dental care and steady exercise. Watch the waistline as activity drops.
Senior (10+): many vets suggest checkups every six months, plus attention to joints, teeth and weight changes.

How much a Irish Setter eats

A spayed or neutered adult around 65 lb needs roughly 1,420 calories a day, about 3.7 cups of a typical 380-calorie-per-cup dry food. See the full feeding guide for a 65 lb dog.
