How French Bulldogs grow
Compact, comical and happy in a small apartment. As a small breed, a French Bulldog is roughly half grown at about 16 weeks and reaches adult size at around 9 to 12 months. The AKC standard caps Frenchies at 28 lb. A Frenchie heading well past that is usually carrying extra fat, which makes breathing harder for this flat-faced breed.
Small and medium puppies have fast metabolisms. Split their food into 3 or 4 meals a day until about 4 months old, then move to 2 or 3 meals.
Is my French Bulldog puppy underweight or overweight?
The scale only tells half the story. Check your puppy's body condition: you should be able to feel the ribs easily under a thin layer of fat, and see a waist when you look down from above. A puppy that tracks low on the chart but has good energy and body condition is usually just going to be a smaller adult. Talk to your vet if your puppy stops gaining for more than two weeks, loses weight, or has persistent diarrhea.
