Irish Terrier Puppy Feeding Schedule

Age-by-age feeding guide for Irish Terrier puppies — from 8 weeks to adulthood

Terrier
medium breed
Adult weight: 25-27 lbs
Switch to adult: 12 months

A Irish Terrier puppy grows from a tiny bundle to a 25-27 lb adult dog in roughly one year, making their first 12 months the most nutritionally demanding period of their life. During this time, your puppy needs the right balance of protein for muscle development, fat for energy and brain growth, and carefully controlled minerals for bone formation. Getting the feeding amounts right at each stage ensures healthy development without the problems that come from under- or overfeeding.
