Your German Shepherd puppy weighs 38 pounds at six months. The chart you found online says 53. So you spend the evening wondering whether you have a runt, a bad breeder, or a health problem.
Probably none of the above. German Shepherds vary in size more than almost any breed that has been formally studied, and the charts floating around the internet mostly hide that fact behind a single tidy number per month.
What follows is a growth chart with the variation left in, plus something more useful: an honest account of which parts of your Shepherd’s growth you can actually influence. Two of the three biggest ones never show up on the scale at all.
The short version
Male German Shepherds reach roughly 65 to 90 pounds and females 50 to 70 pounds, with most of the growth finished by 12 months and the filling out continuing to age two or three. The fastest weight gain happens between two and five months, which is also when the skeleton is most vulnerable. That overlap, not the number on the scale, is what actually matters.

Why this is a range, not a target
In 2017, researchers at the WALTHAM Centre for Pet Nutrition and the University of Liverpool built growth standard charts for dogs using body weight records from more than six million young dogs at Banfield veterinary hospitals. They used the same statistical method the World Health Organisation uses to build children’s growth charts. The German Shepherd was one of only nine breeds common enough in the database to get its own model.
Buried in that paper is a table that says something no breed chart on the internet mentions. For each breed, the researchers measured how much individual dogs varied around the population trend. German Shepherds had the widest spread of any of the nine breeds studied, in both sexes, at every age group they looked at. The variation between individual Shepherds dwarfed the population pattern.
What that means for you: a chart number for a German Shepherd carries less information than the same number would for a Beagle or a Labrador. Your dog sitting 15 pounds off the “average” at nine months is common, not alarming. The shape of the curve over time tells you far more than any single weigh-in.
There is a second reason to treat the numbers loosely. Most charts you will find claim to draw their weight ranges from the AKC breed standard. The actual Official Standard of the German Shepherd Dog contains no weight requirement at all. It specifies height, 24 to 26 inches for males and 22 to 24 inches for females, along with a preferred body proportion of 10 to 8.5. The familiar 65 to 90 pound figure comes from the AKC’s breed profile page, which is a general description rather than the judging standard.
That is not a scandal, but it is worth knowing. The weight ranges below are population descriptions, not a rule your dog is failing to meet.
German Shepherd growth chart by age
The tables below run from one month to three years. The percentage column is the part most owners find useful, because it lets you scale the chart to your own dog rather than to a breed average. If your Shepherd comes from a 70 pound line, the ranges will run high for him and the percentages will still hold.
The third column is the one no competitor publishes: how much weight a puppy typically puts on during that month. It is derived from the midpoint of each range, and it carries the argument in the rest of this article.

Female German Shepherd weight by age
| Age | Typical weight | % of adult weight | Gain that month |
|---|---|---|---|
| 1 month | 4–6 lb | 8% | n/a |
| 2 months | 9–13 lb | 18% | 6 lb |
| 3 months | 15–21 lb | 30% | 7 lb |
| 4 months | 20–28 lb | 40% | 6 lb |
| 5 months | 25–35 lb | 50% | 6 lb |
| 6 months | 29–41 lb | 58% | 5 lb |
| 7 months | 32–46 lb | 65% | 4 lb |
| 8 months | 35–49 lb | 70% | 3 lb |
| 9 months | 38–52 lb | 75% | 3 lb |
| 10 months | 39–55 lb | 78% | 2 lb |
| 11 months | 40–57 lb | 81% | 1.5 lb |
| 12 months | 42–59 lb | 84% | 2 lb |
| 18 months | 48–66 lb | 95% | 1.1 lb |
| 24 months | 49–69 lb | 98% | 0.3 lb |
| 36 months | 50–70 lb | 100% | negligible |
Where these numbers come from, and where they run out. The adult endpoints are the AKC breed profile ranges. The growth trajectory follows the pattern established for large breeds in the veterinary nutrition literature, and the monthly gain figures are calculated from the range midpoints rather than copied from anywhere. Rows past 18 months describe muscle and chest development more than skeletal growth, and the ranges there are deliberately narrow because the real change is small.
One useful reality check on the adult figures. A 2023 study in Scientific Reports weighed young adult dogs entering the Swedish hip screening programme and reported measured mean body weights for 72 breeds. For German Shepherds, drawing on 5,798 males and 6,537 females, the means were 35.7 kg for males and 29.3 kg for females. That is about 79 pounds and 65 pounds, both sitting in the upper half of the AKC ranges rather than the middle.
That same study found German Shepherd body weight drifted down slightly, about 1.7 percent, across the decade it covered. Breed averages are not fixed points.
The pattern to notice in the gain column: growth is front loaded. A male Shepherd puts on more weight between month two and month three than he does across the entire second year of his life. Puppies grow in a steep curve that flattens hard, which is exactly the opposite of the steady, linear pattern seen in kittens over their first months. That difference is why one weight rule can cover every domestic cat, and no single rule covers every dog.
German Shepherd height chart
Height is measured at the withers, the ridge between the shoulder blades, with the dog standing square. It is a more stable signal than weight because it cannot be inflated by body fat.
| Age | Typical height at the withers |
|---|---|
| 3 months | 11–14 in |
| 6 months | 16–20 in |
| 9 months | 20–23 in |
| 12 months | 22–25 in |
| 18 months | 23–26 in |
| Adult male | 24–26 in |
| Adult female | 22–24 in |
Height finishes earlier than weight. Most German Shepherds are at or near their adult height somewhere between 10 and 14 months, and a few take until 18. After that the dog gets broader rather than taller.
When do German Shepherds stop growing?
It depends which kind of growing you mean, and the distinction matters more than it sounds.
Height stops first, usually between 10 and 14 months, when the growth plates in the long bones close. Weight keeps climbing until around 18 months for most dogs. Muscle and chest development continue to roughly two years in females and two and a half in males, and some males are still broadening at three.
The growth plate timing is the practically important one. In an average sized dog, plates close around 12 months. In giant breeds they can stay open until 18 to 20 months, which is why a Great Dane’s growth chart runs on a different timetable and why the giant breeds carry a longer window of skeletal risk. German Shepherds are a large breed rather than a giant one, so they sit between those two schedules, closer to the 12 month end.
Until those plates close, the skeleton is still soft enough to be shaped by what you do. That is the whole reason the next three sections exist.
The fastest growth is the riskiest growth
Look again at the gain column. A male Shepherd is putting on seven to nine and a half pounds a month between two and five months of age. Nothing else in his life comes close to that rate.
That window is also when the skeleton is least able to tolerate a mistake. The foundational research here was done in Great Danes, where feeding excess calcium and excess energy during growth produced measurable disturbances in bone and cartilage development. Growing puppies cannot throttle how much calcium they absorb the way an adult dog can. Give a puppy a calcium rich diet and the puppy takes up more calcium, with no biological brake.
The resulting problems get grouped under developmental orthopedic disease, which covers osteochondrosis, hypertrophic osteodystrophy, panosteitis, and developmental hip and elbow dysplasia. The uncomfortable part is that skeletal changes established during growth are largely permanent. Fixing the diet at ten months does not undo what happened at four.
Feeding less does not mean feeding badly. In a five year study, restricting food intake in growing Labradors reduced the incidence of hip dysplasia and the osteoarthritis that follows it. A lean puppy that grows a little slower ends up with better joints than a chunky littermate that grew fast.
The practical version: you want a German Shepherd puppy you can feel the ribs on, growing at the lower end of the range rather than the upper end. Fast growth is not a sign that you are doing well. In this breed it is a risk factor.
Feeding, and why the answer splits by sex
Large breed puppy food exists to solve the calcium problem above. AAFCO caps calcium at 1.8 percent on a dry matter basis for foods intended for large breed growth, and requires the nutritional adequacy statement on the bag to say the food is suitable for growth of large size dogs, 70 pounds or more as an adult. If the statement instead says the food is for growth except for large size dogs, that bag is the wrong bag.
Here is where German Shepherds get interesting, and where every article on this topic gives an answer that is too simple. AAFCO draws its large breed line at 70 pounds of expected adult weight. The measured mean for male German Shepherds is about 79 pounds, comfortably above the line. The measured mean for females is about 65 pounds, below it.
So the breed straddles the threshold. “Does my German Shepherd need large breed puppy food” does not have one breed level answer. It has an answer that depends on the individual dog’s projected adult weight.
Estimate the adult weight first
Ask the breeder what the parents weigh, since that predicts adult size better than any chart. Failing that, take your puppy’s weight at four months and double it, which lands close for large breeds.
Above 70 pounds projected, use large breed puppy food
This covers most males and the larger females. Check the nutritional adequacy statement on the bag rather than trusting the words on the front, which are marketing.
Below 70 pounds projected, standard puppy food is defensible
Many smaller females fall here. Large breed formulas will not harm them either, so if you are unsure, the controlled calcium version is the safer default.
Do not add calcium supplements
A complete puppy food already contains what the dog needs. Adding calcium on top of a balanced diet is one of the few genuinely harmful things an attentive owner can do during this window.
Two related notes on feeding this breed. German Shepherds are deep chested and carry meaningful bloat risk, so how you feed matters alongside what you feed. The research on raised feeding bowls and bloat found roughly 20 percent of bloat cases in large breed dogs were attributable to the raised bowl, which makes the popular ergonomic feeder a poor default for a Shepherd. And if you are weighing a grain free diet, the reported link between those diets and dilated cardiomyopathy is worth reading before committing a growing large breed dog to one.
The decision that never shows up on the scale
Most articles about German Shepherd growth mention spaying and neutering in the context of size, usually claiming it will make the dog bigger or smaller. The evidence on that is thin. The 2017 growth standards study did find that neutering before 37 weeks was associated with a slight upward shift in growth trajectory and neutering after that with a slight downward shift, but the shifts were small and, in German Shepherds specifically, swamped by how much individual dogs varied anyway.
So the honest answer on size is that timing barely moves it. The honest answer on joints is completely different.
Researchers at UC Davis reviewed 14 and a half years of veterinary hospital records covering 1,170 German Shepherds, published in Veterinary Medicine and Science in 2016. They tracked joint disorders and cancers against the age at which each dog was neutered. The findings were stark:
| Finding | Result |
|---|---|
| Joint disorders, intact males | 7% diagnosed with one or more |
| Joint disorders, males neutered before 1 year | 21%, roughly triple |
| Joint disorders, intact females | 5% |
| Joint disorders, females spayed before 1 year | 16% |
| Mammary cancer, intact females | 4% |
| Mammary cancer, females spayed before 1 year | Under 1% |
| Urinary incontinence, intact females | Not diagnosed |
| Urinary incontinence, females spayed before 1 year | 7% |
The mechanism connects directly back to the growth chart. Sex hormones govern when growth plates close. Remove them early and the plates stay open longer, which changes how the joint assembles itself. The single joint disorder most elevated in the study was cranial cruciate ligament tear, the dog equivalent of an ACL rupture, which is both common and expensive to repair. If you want the cost side of that, we have covered what cruciate surgery runs and how insurers treat it separately.
Two caveats worth stating plainly. This was a referral hospital population, which skews toward sicker dogs, so the absolute percentages likely overstate what you would see in the general pet population. And the spay findings cut both ways, since delaying a spay raises mammary cancer risk while lowering joint risk. This is a real trade off, not a slam dunk, and it belongs in a conversation with your vet rather than being settled by an article.
What is not ambiguous is that the decision is consequential, and that it is invisible on a growth chart.
Hip dysplasia: the number everyone quotes is too low
Search for German Shepherd hip dysplasia and you will be told, repeatedly, that about 20 percent of the breed is affected. That figure comes from the Orthopedic Foundation for Animals database, where 20.4 percent of German Shepherds evaluated between 1974 and 2015 were graded dysplastic.
The problem is that submitting radiographs to the OFA is voluntary. Researchers examining this in 2005 pointed out the obvious consequence: owners and breeders can have films taken privately, see a bad result, and simply never submit it. The database therefore skews healthy.
Studies using populations that were not self selected report considerably higher numbers. A Swedish study scoring pelvic radiographs found hip dysplasia in 49 percent of the German Shepherds tested. An Italian study of nearly 19,000 purebred dogs put German Shepherds at 26.6 percent. Reviewing the range across methods, the Universities Federation for Animal Welfare puts the figure at 18 to 49 percent, and notes the breed carries significantly higher risk than Dobermanns, Labradors, and Rottweilers.
None of that means your puppy is doomed. Hip dysplasia is polygenic and heavily influenced by environment, which is precisely why the feeding and growth rate material above is worth taking seriously. Two things reliably reduce the risk: buying from parents that have been formally hip scored, and keeping the puppy lean while it grows.
How to check your Shepherd without a chart
Body condition beats body weight for the same reason the variation data above matters. A 75 pound Shepherd can be lean and well muscled or soft and overweight, and the scale cannot tell the difference. This four step check takes under a minute.
Feel the ribs
Run your palms along the ribcage with light pressure. You should feel each rib easily, with a thin layer of covering, similar to the back of your hand. If you have to press to find them, the dog is carrying too much.
Look from above
Stand over your dog. You want a visible waist behind the ribcage. A straight line from ribs to hips means excess weight.
Look from the side
The belly should tuck up from the bottom of the ribcage toward the hind legs. A belly running parallel to the ground is a warning sign.
Weigh on the same scale every two weeks
Trend beats snapshot. Two weeks apart on one scale tells you the direction of travel, which is the thing the chart cannot give you.
Frequently asked questions
How much should a 6 month old German Shepherd weigh?
Roughly 38 to 52 pounds for males and 29 to 41 pounds for females, which is about 58 percent of adult weight. Those ranges are wide on purpose. German Shepherds show more individual variation in body weight than any other breed in the largest growth study conducted, so a dog outside the range is not automatically a problem.
How much should a 3 month old German Shepherd puppy weigh?
About 20 to 27 pounds for males and 15 to 21 pounds for females, roughly 30 percent of adult weight. Three months sits inside the fastest growth window of the whole first year, so weight at this age changes quickly week to week.
At what age is a German Shepherd full grown?
There is no single answer, which is why the question causes confusion. Height finishes first, weight second, and body mass last. The practical milestone most owners want is growth plate closure, usually 10 to 14 months, because that is the point at which sustained running, jumping, and hard-surface exercise stop carrying extra risk to the developing skeleton.
How big will my German Shepherd get?
Parent size is the strongest predictor available to you, so ask the breeder for both parents’ adult weights before relying on any chart. Bloodline matters too, since working lines tend to run leaner than show lines. If you have a rescue with unknown parentage, the four month doubling estimate in the feeding section is a reasonable substitute.
Why is my German Shepherd so skinny?
Adolescent Shepherds between roughly six and fourteen months commonly look leggy and narrow, because height finishes before the chest fills in. If you can feel ribs easily but not see them sharply, and the dog is energetic with a normal appetite, that is usually normal development. Visible spine and hip bones, lethargy, or weight loss are different, and warrant a vet visit.
Do male and female German Shepherds grow at different rates?
They follow the same curve shape but at different scales, with males ending roughly 14 pounds heavier on average based on measured data from over 12,000 dogs. Males also take longer to finish filling out. The percentage of adult weight reached at each age is very similar between the sexes, which is why the percentage column is the more portable tool.
How much should I feed a German Shepherd puppy?
Start with the feeding guide on the bag for your puppy’s current weight and expected adult weight, then adjust based on body condition rather than the chart. Aim to keep the puppy lean. Restricting intake during growth reduced hip dysplasia incidence in a five year study of Labradors, and the same principle applies to any large breed.
Should I use large breed puppy food for a German Shepherd?
For most males, yes, since they typically exceed the 70 pound adult weight that defines large breed formulas. For smaller females the standard formula is defensible. If you are unsure which side of the line your dog falls on, the large breed formula is the safer default because its controlled calcium will not harm a smaller dog.
Are working line German Shepherds smaller than show lines?
Generally yes. Working lines are usually leaner and lighter, bred for stamina and agility, while show lines tend to be heavier boned. Both fall within the AKC height specification. This is one of several reasons a single average weight per month is a weak tool for this breed.
When should I spay or neuter my German Shepherd?
Later than the default six month appointment, based on the UC Davis data, but the exact timing is a conversation with your vet rather than a fixed rule. Bring the specifics they will need: your dog’s sex, whether the breeding lines have a joint disorder history, and whether managing an intact dog is realistic in your household. The point is to make it a decision rather than a scheduling default.
Is my German Shepherd overweight?
Use the four step body condition check above rather than the scale. Ribs easy to feel under light pressure, a visible waist from above, and an abdominal tuck from the side together indicate healthy condition. Excess weight matters more in this breed than most, because body weight is a known risk factor for the degenerative joint disease that follows hip dysplasia.
Do German Shepherds have a growth spurt?
The whole period from two to five months functions as one long spurt rather than a discrete event. During those months a male puppy gains seven to nine pounds monthly, more than he will gain across his entire second year. Growth then decelerates steadily rather than stopping abruptly.
The bottom line
Use the chart to check the shape of your dog’s growth, not to hit a number. German Shepherds vary more than the charts admit, and a dog sitting well off the average is usually just a dog.
The things that genuinely shape how this breed’s joints hold up are decisions rather than measurements. Keep the puppy lean through the fast growth months between two and five. Match the food to your dog’s projected adult weight instead of the breed label. Talk to your vet about waiting past twelve months to neuter. None of those show up on a scale, and all three matter more than whether your six month old weighs 44 pounds or 50.
How we researched this. Weight and height ranges are built from the AKC breed profile endpoints and the large breed growth pattern in the veterinary nutrition literature, with monthly gain figures derived from range midpoints rather than sourced from other charts. The variation findings and neutering effects on growth come from Salt et al., PLOS ONE 2017, a study of more than six million dogs. Adult weight means come from Andersson et al., Scientific Reports 2023. The neutering and joint disorder figures come from Hart et al., Veterinary Medicine and Science 2016. Hip dysplasia prevalence ranges are drawn from the UFAW genetic welfare review. This article is general information and is not a substitute for veterinary advice about your individual dog.
