How this was calculated

For a Bernese Mountain Dog we use the giant-breed growth curve (matures around 22 months): adult weight ≈ current weight ÷ the fraction of adult weight a giant breed reaches at this age. Typical adult weight (70–115 lb) is from the AKC breed standard. The gauge shows where your prediction lands against the breed-typical adult range.

Bernese Mountain Dog growth, explained

Bernese Mountain Dogs are a giant breed, so they follow the giant-breed growth curve. AKC: males 80–115 lb, females 70–95 lb. Big and slow-maturing — let them grow gradually. Most reach close to their adult weight by around 22 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 giant breed has typically reached at that age. Typical adult weight (70–115 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 Bernese Mountain Dog looks heavier or lighter than the breed-typical band, your vet is the best person to check.
