How this was calculated
For a Labrador Retriever we use the large-breed growth curve (matures around 16 months): adult weight ≈ current weight ÷ the fraction of adult weight a large breed reaches at this age. Typical adult weight (55–80 lb) is from the AKC breed standard. The gauge shows where your prediction lands against the breed-typical adult range.

Labrador Retriever growth, explained
Labrador Retrievers are a large breed, so they follow the large-breed growth curve. AKC: males 65–80 lb, females 55–70 lb. Labs pile on weight easily — keep them lean for their joints. Most reach close to their adult weight by around 16 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 large breed has typically reached at that age. Typical adult weight (55–80 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 Labrador Retriever looks heavier or lighter than the breed-typical band, your vet is the best person to check.
