Uses the common size-based chart: the first year equals about 15 human years, the second adds about 9, and each year after that adds 4 (small), 5 (medium), 6 (large) or 7 (giant). It is an estimate, not a medical measure.

What each stage means for a Lhasa Apso

Young adult (1–3): still learning. Keep training consistent and set the healthy weight now; for a Lhasa Apso that is usually within 12–18 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 Lhasa Apso eats

A spayed or neutered adult around 15 lb needs roughly 470 calories a day, about 1.2 cups of a typical 380-calorie-per-cup dry food. See the full feeding guide for a 15 lb dog.
