Use this Beagle weight chart in kg and lb by age to compare male and female puppy ranges, 13-inch vs 15-inch size context, adult weight, and healthy body condition. Beagles grow into compact scent hounds, and their happiest adult weight usually comes from measured food, daily sniff work, and honest tracking of treats, scavenging, and food access.
A Beagle can be active and still gain weight, so the scale, ribs, waist, and food access all have to tell the same story.

Quick answers
Use these answers for the most common Beagle weight chart, kg, male/female, size, and healthy-weight questions before reading the full table.
Adult range
AKC lists Beagles in two height varieties: 13 inches and under, and over 13 inches but not over 15 inches. The smaller variety is commonly under 20 lb, while the 13-15 inch variety is commonly 20-30 lb.
kg chart
Many adult Beagles fall around 9-14 kg, with smaller 13-inch dogs often toward the lower end and taller 15-inch dogs often toward the upper end. Male and female puppy ranges overlap, so size variety and body condition matter.
6 months
Many 6-month Beagles fall around 15-23 lb (6.8-10.4 kg), with smaller 13-inch dogs often lower and taller 15-inch dogs often higher. Use the two-to-three-week trend, not one weigh-in after a treat-heavy week.
Full grown
Many Beagles reach most of their height near the first birthday, then settle into adult muscle and condition through about 18 months. Adult weight is strongly shaped by measured meals and food security.
30 lb check
Thirty pounds can fit a taller 15-inch Beagle with good muscle, easy-to-feel ribs, and a visible waist. For a smaller Beagle, or any Beagle with a rounded waist and padded ribs, it is a body-condition warning.
Weight by age
This Beagle growth chart shows male and female weight by age in both pounds and kilograms. Beagles come in two height varieties, so a smaller 13-inch Beagle and a taller 15-inch Beagle can both be healthy at different adult weights.
Many adults fall around 20-30 lb (9.1-13.6 kg), and the healthiest goal is usually a sturdy waist, not the top number.
Because Beagles are scent-driven and often intensely food-motivated, this chart works best when you log meals, treats, stolen food, stool, and daily exercise with each weigh-in.
| Age | Typical Male Weight (lb and kg) | Typical Female Weight (lb and kg) |
|---|---|---|
| 2 months | 5-8 lb (2.3-3.6 kg) | 4-7 lb (1.8-3.2 kg) |
| 3 months | 8-12 lb (3.6-5.4 kg) | 7-11 lb (3.2-5 kg) |
| 4 months | 11-16 lb (5-7.3 kg) | 10-15 lb (4.5-6.8 kg) |
| 5 months | 14-20 lb (6.4-9.1 kg) | 13-18 lb (5.9-8.2 kg) |
| 6 months | 16-23 lb (7.3-10.4 kg) | 15-21 lb (6.8-9.5 kg) |
| 8 months | 19-27 lb (8.6-12.2 kg) | 17-25 lb (7.7-11.3 kg) |
| 10 months | 21-30 lb (9.5-13.6 kg) | 19-27 lb (8.6-12.2 kg) |
| 12 months | 22-30 lb (10-13.6 kg) | 20-28 lb (9.1-12.7 kg) |
| 18 months | 20-30 lb (9.1-13.6 kg) | 20-30 lb (9.1-13.6 kg) |
Popular checkpoints
These quick answers cover the month-old, adult-weight, and full-grown size lookups owners most often compare after opening the chart, with values shown in both kg and lb whenever that context is available.
At around 12 weeks (3 months), male Beagle puppies are often around 8-12 lb (3.6-5.4 kg), while females are often around 7-11 lb (3.2-5 kg). Use that checkpoint as a guide and focus on a steady trend over time.
At around 5 months, male Beagle puppies are often around 14-20 lb (6.4-9.1 kg), while females are often around 13-18 lb (5.9-8.2 kg). Use that checkpoint as a guide and focus on a steady trend over time.
At around 8 months, male Beagle puppies are often around 19-27 lb (8.6-12.2 kg), while females are often around 17-25 lb (7.7-11.3 kg). Use that checkpoint as a guide and focus on a steady trend over time.
Most healthy adult Beagle dogs land around 9.1-13.6 kg (20.1-30 lb), though frame, sex, and routine still create normal variation.
Beagle dogs are usually close to full height by around 12 to 15 months, but healthy adult muscle, chest depth, and overall frame can keep filling in after the fastest puppy-growth stage.
Maturity
Most Beagles reach close to adult height by the first year, then settle into adult muscle, appetite control, and hound condition over the next several months. Owners asking when Beagles stop growing should watch height, waist, rib feel, and food routine, not weight alone.
Legs, ribs, and appetite grow quickly. Measured meals matter because the nose starts finding extras early.
The body becomes more recognizable as a Beagle, and excess snacks may start to show around the waist.
Height is often close to mature, but muscle, chest, and daily condition are still changing.
Meal habits, scent work, leash exercise, and food security shape the adult trend.
Key takeaway
A healthy Beagle should feel solid and athletic, with ribs easy to find and food intake controlled by people.
Growth check
A healthy Beagle puppy looks sturdy, curious, and energetic without losing waist shape under the hound build.
Scent-hound note
For Beagles, the chart is only accurate when stolen snacks, training treats, and scavenging are counted honestly.
Weight factors
Beagle weight is shaped by size variety, appetite, scent-driven behavior, activity, ear comfort, and how tightly the home controls food access.
AKC and the National Beagle Club recognize 13-inch and 15-inch varieties. A smaller Beagle should not be pushed toward the same number as a taller 15-inch Beagle.
Many Beagles will overeat if given the chance, so portions need to be planned.
Following scent trails burns energy, but it can also lead to food finds and unsafe swallowing.
Ear irritation can reduce play and make weight creep easier to miss.
Use small rewards and subtract them from the day's food.
Persistent scratching, weight gain without more food, or stool changes deserve a vet check.

What this means
When to re-check
Re-check a Beagle every 2 to 3 weeks during growth, and sooner after a change in food access, treat use, exercise, or ear/skin comfort.
Next action

Stages
Beagle growth is a mix of medium-hound frame, huge scent interest, appetite management, and steady social development.
Birth - 8 weeks
Early records, weaning, handling, and litter health give context before the puppy comes home.
2 - 4 months
Start measured meals, safe confinement, ear handling, leash basics, and name response.
4 - 7 months
Scent drive rises quickly. Use sniff walks, recall games, and small rewards rather than open food access.
7 - 12 months
The puppy may look adult but still needs controlled portions, training, and supervision around food.
12 - 18 months
Muscle and routine settle. Watch for weight creep if exercise drops.
18+ months
Adult care centers on meal control, ear checks, skin comfort, scent work, and waist monitoring.
Feeding rules
Guessing portions rarely works well with a food-driven Beagle.
Scheduled meals make appetite, stool, and weight easier to track.
Puppy food supports growth until maturity and your vet's advice line up.
Tiny rewards keep training moving without adding a second meal.
Water matters during warm sniff walks, play, and diet transitions.
Slow transitions help you spot stool changes, itching, appetite shifts, or weight jumps.
Feeding
Beagle portions depend on age, adult size variety, food calories, activity, body condition, treats, and whether the dog is finding extra food outside the bowl.
Puppy rhythm
Regular meal times help you compare appetite, stool, and weight during fast growth.
Reward rule
Use part of the daily ration for training when scent work or recall practice needs many repetitions.
Home setup
Secure trash, counters, bags, and children's snacks because stolen food can undo careful portions.
Daily life
Good fit for
Things to watch
Care
Use measured meals, avoid free-feeding, and count every training treat because Beagles are famously food-motivated.
Give daily leash walks, sniffing routes, and scent games while avoiding unsupervised roaming after smells.
Brush the short coat weekly, check skin, and keep ear cleaning on the routine your vet recommends.
Use short reward sessions, secure food storage, and recall practice built around the Beagle's nose.
Warning signs
A Beagle should be sturdy, but sturdy is not the same as padded. Use hands-on checks often.
