Beagle Growth Chart
Beagles are sturdy scent hounds with a food-driven appetite and steady growth through the first year. Most reach adult weight between 12 and 15 months. Regular weigh-ins help distinguish healthy growth from excess weight on a compact frame.

Beagle Growth Stages
Understanding the typical growth stages helps you know what to expect as your Beagle puppy grows.
Neonatal
0–2 weeksPuppies are born with eyes and ears closed, relying entirely on their mother. Rapid weight gain occurs during this period.
Socialization
3–12 weeksEyes and ears open. Puppies begin to explore, play, and learn social behaviors. This is a critical period for development.
Juvenile
3–6 monthsRapid growth continues. Puppies become more independent, start teething, and develop coordination.
Adolescent
6–12 monthsGrowth rate begins to slow. Puppies reach sexual maturity and may test boundaries. Muscle mass develops.
Young Adult
12–15 monthsGrowth is nearly complete. Your puppy is filling out and approaching adult proportions.

Beagle FAQ
How much will my Beagle puppy weigh as an adult?
As a medium breed, Beagles usually reach an estimated adult range of 20–30 lb overall. Sex matters: males typically finish around 20–30 lb and females around 20–30 lb. Track weekly weigh-ins to see whether your puppy trends toward the lower or upper end.
At what age is a Beagle fully grown?
Beagles are medium dogs that typically reach most of their adult weight between 12 and 15 months. Beagles gain steadily through the first year and typically settle by 12–15 months. Slight muscle or coat fill may continue briefly after height stabilizes, so weekly weigh-ins give a clearer picture than a single reading.
How accurate is a Beagle puppy weight chart?
Chart accuracy for Beagles depends on individual build. Differences in 13-inch versus 15-inch height varieties can shift results, since food-driven appetites can blur growth versus excess weight. Weekly weigh-ins on the same scale and time of day typically improve estimate quality over time.
