If you’ve just brought home a Polish Lowland Sheepdog puppy, the calculator below estimates its adult size from its current weight — personalized to your dog, not just a breed average.
Estimates combine your puppy’s current trajectory with typical growth curves for this breed and size class. Individual dogs vary — nutrition, genetics and neuter timing all matter. For health concerns, ask your vet.
The Polish Lowland Sheepdog is a medium-sized breed. Adult males typically weigh 30–50 lb (13.6–22.7 kg) and females 30–50 lb (13.6–22.7 kg). Most Polish Lowland Sheepdogs 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 Polish Lowland Sheepdogs stop growing?
Most Polish Lowland Sheepdogs 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 Polish Lowland Sheepdog puppy weigh at 4 months?
A typical 4-month-old Polish Lowland Sheepdog weighs roughly 14–23 lb, about 46% of its adult weight. Use the calculator above with your puppy’s exact weight for a personalized estimate — individual dogs vary.
