How this was calculated
For a French Bulldog we use the small-breed growth curve (matures around 12 months): adult weight ≈ current weight ÷ the fraction of adult weight a small breed reaches at this age. Typical adult weight (16–28 lb) is from the AKC breed standard. The gauge shows where your prediction lands against the breed-typical adult range.

French Bulldog growth, explained
French Bulldogs are a small breed, so they follow the small-breed growth curve. AKC standard: under 28 lb (typically 16–28). A compact, fast-finishing breed — keep them trim, extra weight strains their breathing. Most reach close to their adult weight by around 12 months, then continue to firm up in muscle and chest for a while after.
To predict an adult weight we divide your puppy’s current weight by the fraction of adult weight a small breed has typically reached at that age. Typical adult weight (16–28 lb) is from the AKC breed standard. The result is an estimate with a likely range — genetics and nutrition move individual dogs up or down. If your French Bulldog looks heavier or lighter than the breed-typical band, your vet is the best person to check.
