The German Pinscher is a medium-sized breed. Adult males typically weigh 25–45 lb (11.3–20.4 kg) and females 25–45 lb (11.3–20.4 kg). Most German Pinschers reach about half their adult weight around 4.3 months, hit 90% by roughly 9.1 months, and are fully grown near 13 months. A useful rule of thumb for medium breeds: they roughly double their four-month weight.
When do German Pinschers stop growing?
Most German Pinschers reach their full adult height and weight by about 13 months. Growth is fastest before 4.3 months, then slows steadily — by 9.1 months your puppy will be about 90% of its final size.
How much should a German Pinscher puppy weigh at 4 months?
