Beagle Puppy Weight Calculator & Growth Chart
A sturdy hound breed with high bone density and muscular drive. Beagles have a voracious appetite that must be regulated to prevent early obesity.

Beagle Pediatric Growth Trajectory
Biological sigmoid curve showing healthy weight progression by age (weeks).
Shaded area represents healthy ±1 standard deviation AKC breed corridor.
Growth Velocity Note
Quick, even growth between weeks 8 and 20. Skeletal frames solidify around 10 months.
Veterinary Feeding Guidance:
Use a digital kitchen scale to measure daily kibble grams; Beagles rarely self-regulate food intake.
Beagle Week-by-Week Weight Milestones
Reference data for healthy Beagle puppies based on veterinary pediatric percentiles.
| Puppy Age | Expected Weight (lbs) | Expected Weight (kg) | Developmental Milestone |
|---|---|---|---|
| 8 Weeks (2 mo) | 4.5–7.5 lbs | 2.0–3.4 kg | Active sensory development |
| 12 Weeks (3 mo) | 8.5–13.5 lbs | 3.9–6.1 kg | Torso and scenting stamina growth |
| 16 Weeks (4 mo) | 12.5–18.0 lbs | 5.7–8.2 kg | ~55% adult weight |
| 24 Weeks (6 mo) | 16.0–23.0 lbs | 7.3–10.4 kg | Hound musculature emerges |
| 36 Weeks (8 mo) | 18.0–26.0 lbs | 8.2–11.8 kg | Near adult weight |
| 52 Weeks (12 mo) | 18.0–30.0 lbs | 8.2–13.6 kg | Full AKC adult benchmark |
When Do Beagle Growth Plates Close?
For the Beagle (small breed classification), epiphyseal growth plates typically close between 10–12 months. Until these cartilaginous zones calcify into solid bone, the skeletal structure is particularly vulnerable to impact trauma.
- Avoid repetitive high-impact jumping (such as off tall beds or out of SUVs).
- Postpone intense agility hurdles or forced running on concrete until growth plate fusion is complete.
- Maintain lean body condition: excess puppy fat places unnecessary biomechanical torque on immature ligaments.
Nutrition & Weight Maintenance
Caloric demand peaks between 8 and 16 weeks, during which puppies require up to twice the calories per pound of body weight compared to adult dogs.
Use a digital kitchen scale to measure daily kibble grams; Beagles rarely self-regulate food intake. Weigh your puppy bi-weekly and adjust portions according to their body condition score (BCS) rather than bag recommendations alone.
Beagle Weight & Size Questions
What is the healthy weight for an adult Beagle?
The AKC recognizes two varieties: 13-inch Beagles typically weigh under 20 lbs, while 15-inch Beagles weigh 20 to 30 lbs.
When do Beagles stop growing?
Beagles stop growing taller around 8 to 10 months, reaching their final adult weight and muscle profile around 12 to 14 months.
