Medium Breed Puppy Growth Charts
Medium breeds cover the most popular family dogs, from spaniels to collies. They grow fast in the first half-year, then spend months filling out — the scale may stall while the body keeps changing.
Most medium breeds approach adult weight around 14 months, though muscle and coat keep maturing into the second year.

Medium puppy growth FAQ
How much should a medium breed puppy weigh?
Adult medium breeds typically weigh between 25 and 50 lb. Your puppy’s age, current weight, and parents’ size help narrow where they may land.
When do medium breed puppies stop growing?
Most medium puppies reach adult weight around 14 months. Large-framed individuals within this group can take a little longer.
Why did my medium puppy’s growth slow down?
Growth naturally tapers after 6–8 months as the skeleton nears full size. A flattening curve is expected; a sudden stall or drop deserves a vet check.
