What each stage means for a Pembroke Welsh Corgi

Young adult (1–3): still learning. Keep training consistent and set the healthy weight now; for a Pembroke Welsh Corgi that is usually within 25–30 lb.
Mature adult (3–8): yearly checkups, dental care and steady exercise. Watch the waistline as activity drops.
Senior (9+): many vets suggest checkups every six months, plus attention to joints, teeth and weight changes.
