Large breeds take longer to mature, typically reaching their adult weight around 14–18 months. They grow rapidly between 3–6 months.
A Rottweiler's growth rate is fastest in the first 6 months of life. For larger breeds like the Rottweiler, it's important not to over-feed during the growth phase, as rapid weight gain can put stress on developing joints and bones.
Factors that influence your Rottweiler's adult size include genetics (parent size), nutrition quality, spay/neuter timing, and overall health. Males typically weigh 10–20% more than females.
