Large breeds take longer to mature, typically reaching their adult weight around 14–18 months. They grow rapidly between 3–6 months.
A Labrador Retriever's growth rate is fastest in the first 6 months of life. For larger breeds like the Labrador Retriever, it's important not to over-feed during the growth phase, as rapid weight gain can put stress on developing joints and bones.
