Great Dane Puppy Weight Calculator & Growth Chart
The gentle giant of the canine world. Great Danes exhibit the longest developmental curve of any domestic breed, gaining up to 3 to 5 lbs per week during peak growth stages.

Great Dane 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
Extreme velocity between 12 and 32 weeks. Epiphyseal growth plates remain open past 18 months, with full mass stabilizing at 2 years of age.
Veterinary Feeding Guidance:
Strictly use giant-breed pediatric formulations with controlled energy and restricted calcium to prevent hypertrophic osteodystrophy (HOD) and panosteitis.
Great Dane Week-by-Week Weight Milestones
Reference data for healthy Great Dane puppies based on veterinary pediatric percentiles.
| Puppy Age | Expected Weight (lbs) | Expected Weight (kg) | Developmental Milestone |
|---|---|---|---|
| 8 Weeks (2 mo) | 18–26 lbs | 8.2–11.8 kg | Heavy paw and bone foundation |
| 12 Weeks (3 mo) | 35–50 lbs | 15.9–22.7 kg | Intense limb elongation phase |
| 16 Weeks (4 mo) | 55–75 lbs | 24.9–34.0 kg | ~35-40% of adult giant weight |
| 24 Weeks (6 mo) | 80–110 lbs | 36.3–49.9 kg | Secondary growth surge |
| 36 Weeks (8 mo) | 105–140 lbs | 47.6–63.5 kg | Height stabilization |
| 52 Weeks (12 mo) | 120–165 lbs | 54.4–74.8 kg | Chest deepening through year two |
When Do Great Dane Growth Plates Close?
For the Great Dane (giant breed classification), epiphyseal growth plates typically close between 18–24 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.
Strictly use giant-breed pediatric formulations with controlled energy and restricted calcium to prevent hypertrophic osteodystrophy (HOD) and panosteitis. Weigh your puppy bi-weekly and adjust portions according to their body condition score (BCS) rather than bag recommendations alone.

Great Dane Weight & Size Questions
How much should a Great Dane puppy weigh at 4 months?
At 16 weeks (4 months), a healthy Great Dane puppy weighs between 55 and 75 lbs. Males trend toward the upper boundary of this range.
When do Great Danes stop growing?
Great Danes achieve most of their impressive vertical height by 12 to 15 months, but continue gaining chest breadth, muscle mass, and bone density until 24 months.
