What each stage means for a Bulldog

Young adult (1–3): still learning. Keep training consistent and set the healthy weight now; for a Bulldog that is usually within 40–50 lb.
Mature adult (3–6): yearly checkups, dental care and steady exercise. Watch the waistline as activity drops.
Senior (7+): many vets suggest checkups every six months, plus attention to joints, teeth and weight changes.

How much a Bulldog eats

A spayed or neutered adult around 45 lb needs roughly 1,080 calories a day, about 2.8 cups of a typical 380-calorie-per-cup dry food. See the full feeding guide for a 45 lb dog.
