How this was calculated
For a Australian Cattle Dog we use the medium-breed growth curve (matures around 14 months): adult weight ≈ current weight ÷ the fraction of adult weight a medium breed reaches at this age. Typical adult weight (35–50 lb) is from the AKC breed standard. The gauge shows where your prediction lands against the breed-typical adult range.

About our figures →Australian Cattle Dog growth, explained
Australian Cattle Dogs are a medium breed, so they follow the medium-breed growth curve. AKC: about 35–50 lb. A working dog — lean and athletic, not heavy. Most reach close to their adult weight by around 14 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 medium breed has typically reached at that age. Typical adult weight (35–50 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 Australian Cattle Dog looks heavier or lighter than the breed-typical band, your vet is the best person to check.
