Is My Miniature Bull Terrier Overweight?

To determine if your Miniature Bull Terrier is at a healthy weight (18–28 lbs target):

Rib test: You should be able to feel the ribs without pressing hard, with a thin layer of fat covering them
Waist check: Viewed from above, there should be a visible waist behind the ribs
Tuck-up: From the side, the abdomen should tuck up behind the rib cage

Their coat type allows for relatively easy visual assessment. If your Miniature Bull Terrier is overweight, work with your veterinarian to develop a safe weight loss plan. Even a 10% reduction can reduce the risk of Primary Lens Luxation and other conditions.
