Use this Great Dane weight and growth chart by age in kg and lb to compare male and female puppy ranges, 6-month size, adult weight, and height context. Great Danes grow for a long time, and the safest curve is steady rather than rushed, so read every number beside body condition, movement comfort, feeding routine, and bloat-aware care.
Great Danes often gain height before adult mass, so slow steady development is the goal even when they look all legs.

Quick answers
Use these answers for the most common Great Dane weight, kg chart, growth chart, and size questions before reading the full table.
Adult range
The AKC breed profile lists adult Great Dane males around 140-175 lb (64-79 kg) and females around 110-140 lb (50-64 kg). A healthy individual can still vary by frame, but the dog should look lean and balanced, not padded.
kg chart
A Great Dane kg chart usually places many 6-month males around 29-45 kg and females around 25-39 kg. Adult males are often around 64-79 kg, while adult females are often around 50-64 kg.
6 months
Many 6-month Great Danes fall around 65-100 lb (29-45 kg) for males and 55-85 lb (25-39 kg) for females. Use repeat weigh-ins and body condition because giant puppies can look leggy, narrow, or uneven while growing.
Full grown
Great Danes often gain height first, then finish muscle and body balance later. Do not rush a puppy toward adult mass; controlled growth is kinder to developing bones and joints.
Height
Official standard context puts males at least 30 inches at the shoulder, with 32 inches or more preferred if balanced, and females at least 28 inches, with 30 inches or more preferred if balanced.
Weight by age
This Great Dane growth chart shows male and female weight by age in both kilograms and pounds, with height notes where they help explain size. Great Danes are one of the tallest dog breeds, and their growth pattern is long, broad, and uneven compared with smaller breeds, so healthy tracking depends on repeat weigh-ins, lean body condition, controlled feeding, and comfortable movement.

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 Great Dane puppies are often around 14-20 kg (30-45 lbs), while females are often around 11-16 kg (24-35 lbs). Use that checkpoint as a guide and focus on a steady trend over time.
At around 5 months, male Great Dane puppies are often around 27-39 kg (60-85 lbs), while females are often around 20-32 kg (45-70 lbs). Use that checkpoint as a guide and focus on a steady trend over time.
At around 8 months, male Great Dane puppies are often around 36-54 kg (80-120 lbs), while females are often around 32-48 kg (70-105 lbs). Use that checkpoint as a guide and focus on a steady trend over time.
Most healthy adult Great Dane dogs land around 50-79 kg (110.2-174.2 lb), though frame, sex, and routine still create normal variation.
Great Dane dogs are usually close to full height by around 18 to 24 months, but healthy adult muscle, chest depth, and overall frame can keep filling in after the fastest puppy-growth stage.
Adult male Great Dane dogs often stand around 30-32+ in at the shoulder, while females are often around 28-30+ in. Use height as a frame check alongside weight and body condition.
Maturity
Great Danes mature slowly. Many look tall before they are finished, so owners asking when Great Danes stop growing usually need two answers: height often settles first, while muscle, chest depth, weight, and coordination can keep developing into the second year.
A Dane puppy may gain height quickly and look all legs. Keep meals measured and activity controlled instead of pushing for bulk.
Height gain slows for many dogs, but chest depth, coordination, and muscle are still developing.
Many Great Danes continue filling out through the second year. The goal is lean substance, not maximum weight.
Adult care shifts toward steady body condition, joint comfort, measured meals, and bloat-aware routines.
Key takeaway
Fast early weight gain does not make a better adult. Lean, steady growth supports movement, joint comfort, and long-term health.
Growth check
Healthy Great Dane growth combines steady weight gain, a visible waist, comfortable movement, age-appropriate energy, and calm recovery after meals and activity.
Giant-breed check
For Great Danes, movement comfort and body condition often reveal more than one heavy weigh-in.
Weight factors
Great Dane weight is shaped by sex, height, frame, growth speed, feeding formula, meal rhythm, movement comfort, and health history.
AKC profile ranges place males around 140-175 lb and females around 110-140 lb, so compare your dog with the right sex and frame context.
Extra calories can make a giant puppy look impressive early, but controlled growth is safer for bones, joints, and long-term movement.
A complete diet labeled for large-size growth helps manage calories, calcium, phosphorus, and mineral balance during the long puppy stage.
A Great Dane should have rib feel and a waist. Heavy fat over the ribs, neck, spine, or tail base is not useful adult substance.
Meal size, meal speed, stress around feeding, raised bowls, and exercise timing deserve attention because GDV is an emergency risk in deep-chested giant breeds.
Feeding
Feeding profile
Choose a complete large/giant-breed growth formula for puppies and measure portions consistently. Do not add calcium or vitamin supplements unless your veterinarian directs it.
Meal rhythm
Young giant puppies often do best with multiple smaller meals. Adults commonly settle into two measured meals, but the exact rhythm should fit appetite, stool, growth, and veterinary advice.
Bloat awareness
Use slow feeders or food puzzles for dogs that inhale meals, feed in a calm place, avoid competition around food, and ask your vet about prophylactic gastropexy for high-risk dogs.
Portion tracking
A kitchen scale is more consistent than a cup. On a giant puppy, small daily overages can become meaningful weight jumps over several weeks.
Stages
Great Danes grow through distinct phases, each with different nutrition, activity, and health considerations. Understanding these stages helps you keep growth steady without adding unnecessary joint or digestive risk.
Birth - 8 weeks
Rapid early development. Puppies rely on breeder and veterinary oversight, stable nursing, careful weaning, and early records before home chart tracking begins.
2 - 6 months
Weight can rise quickly, but fast gain is not the goal. Bones and joints are forming, so avoid overfeeding, free-feeding, and unnecessary calcium or vitamin D supplements.
6 - 12 months
Height may continue rising fast while weight gain becomes less dramatic. Keep the puppy lean, use a large/giant-breed growth diet, and let your veterinarian guide meal frequency.
12 - 18 months
Height starts leveling for many Danes, but body balance and muscle are not finished. Adult-food timing should be based on skeletal maturity, condition, and veterinary guidance.
18 - 24 months
Most Danes are near adult height, while lean muscle and chest depth continue settling. Do not turn this stage into a calorie push for maximum size.
2+ years
Adult care centers on measured meals, lean condition, joint comfort, calm exercise routines, and knowing GDV warning signs.

What this means
When to re-check
Re-check a Great Dane every 2 to 4 weeks through the extended growth phase, because giant-breed trends tell a clearer story over time than week by week.
Next action
Most useful after a fresh weigh-in, then compare the result back against this breed graph and the matching size chart.
Feeding rules
Use scheduled measured meals instead of free-feeding so growth, appetite, stool, and body condition are easier to track.
Avoid intense exercise close to meals and give the dog calm time before and after eating, especially if the dog gulps food.
Choose a complete diet labeled for growth of large-size dogs so calories, calcium, phosphorus, and mineral balance fit a giant puppy.
Many giant-breed puppies need growth nutrition longer than small breeds. Ask your veterinarian before switching early or adding supplements.
Veterinary sources now list raised bowls among GDV risk factors. Use floor-level or vet-directed feeding setups and prioritize slow, calm meals.
Always provide unlimited fresh water - large breeds are more prone to dehydration, especially after activity.

Things to watch
Care
Use measured giant-breed portions and focus on steady growth rather than fast gain.
Controlled low-impact movement is more useful than intense exercise during growth.
Low coat maintenance, but large-body checks should stay routine.
Calm handling and early consistency matter because size changes quickly.
Warning signs
Because Great Danes grow so rapidly and their healthy weight range is wide, it can be difficult to know when your dog has crossed into unhealthy territory. Here are the clear red flags to watch for.
