Puppy Weight Growth Chart by Breed (0–24 Months)
A Golden Retriever puppy weighs about 10–15 lbs at 8 weeks and will reach roughly 65 lbs by 12 months. A Chihuahua puppy starts at half a pound and tops out around 5 lbs. Both are growing exactly as they should — just on completely different clocks. Knowing what's normal for your puppy's breed helps you spot problems early, before they turn into expensive vet visits.
Growth rate is determined almost entirely by adult size. According to Royal Canin and WALTHAM research, toy breeds reach adult weight by 8–12 months, while giant breeds keep growing for 18–24 months. That single fact drives everything: how much to feed, when to switch to adult food, and when to stop worrying — or start.
This chart gives you month-by-month weight ranges for popular breeds across all five size categories, plus a simple formula to estimate your puppy's adult weight. No app download, no math worksheet — just tables you can screenshot and stick on the fridge.

How Fast Do Puppies Grow? The 4 Growth Timelines
Here's the fundamental rule of puppy growth: the bigger the adult dog, the longer growth takes. A toy breed sprints through puppyhood in under a year. A giant breed is still filling out its frame on its second birthday. This isn't a minor difference — it changes how you feed, train, and monitor your puppy at every stage.
| Size Category | Adult Weight Range | Growth Duration | Growth Rate | When Skeletal Maturity |
|---|---|---|---|---|
| Toy | Under 9 lbs (<4 kg) | 0–12 months | Fast — reach 50% adult weight by 11 weeks | 8–10 months |
| Small | 9–22 lbs (4–10 kg) | 0–12 months | Fast — reach 50% adult weight by 14 weeks | 10–12 months |
| Medium | 22–55 lbs (10–25 kg) | 0–18 months | Moderate — reach 50% adult weight by 16 weeks | 12–16 months |
| Large | 55–90 lbs (25–40 kg) | 0–24 months | Slow — reach 50% adult weight by 20 weeks | 16–20 months |
| Giant | 90+ lbs (40+ kg) | 0–24 months | Very slow — reach 50% adult weight by 23 weeks | 18–24 months |
The key insight: Toy breeds grow up fast — a Chihuahua is essentially a full-grown adult by 10 months. But a Great Dane keeps growing until 24 months. The bigger the breed, the longer growth takes — and the more important it is NOT to rush it. Skeletal maturity is the milestone that matters; a dog may look "done" growing months before the growth plates in its bones actually close.

Puppy Weight Chart — Toy Breeds (Under 10 lbs Adult)
Toy puppies are measured in ounces, not pounds — and they grow at a remarkable pace relative to their size. Most toy breeds hit half their adult weight by 11 weeks and are essentially done growing by their first birthday. Because the numbers are so small, a kitchen scale or pet scale is far more useful than a bathroom scale for tracking.
| Age | Chihuahua (1.5–3 kg) | Pomeranian (1.5–3.2 kg) | Yorkshire Terrier (2–3.5 kg) | Maltese (1.8–3 kg) | Toy Poodle (2–3 kg) |
|---|---|---|---|---|---|
| 8 weeks | 0.5–0.8 lbs | 0.6–1.0 lbs | 0.7–1.1 lbs | 0.6–1.0 lbs | 0.6–0.9 lbs |
| 3 months | 1.0–1.8 lbs | 1.3–2.2 lbs | 1.5–2.5 lbs | 1.3–2.0 lbs | 1.2–1.8 lbs |
| 4 months | 1.5–2.5 lbs | 2.0–3.5 lbs | 2.2–3.5 lbs | 2.0–3.0 lbs | 1.8–2.8 lbs |
| 6 months | 2.0–3.5 lbs | 2.5–5.0 lbs | 3.0–5.0 lbs | 2.5–4.5 lbs | 2.5–4.5 lbs |
| 9 months | 3.0–5.5 lbs | 3.0–7.0 lbs | 4.0–7.0 lbs | 3.5–6.0 lbs | 4.0–6.0 lbs |
| 12 months (adult) | 3.3–6.6 lbs | 3.0–7.0 lbs | 4.4–7.7 lbs | 4.0–6.6 lbs | 4.0–6.0 lbs |
How to use this table:
- Toy breeds reach adult weight by 10–12 months.
- After 6 months, growth slows significantly — most of the remaining gain is subtle.
- Small variations are normal — focus on the trend, not exact numbers. A puppy that tracks steadily along its own curve is healthier than one that hits an "average" number after a growth spurt and a stall.
- If your puppy's weight crosses more than 2 category bands, consult your vet.
See the Chihuahua weight & calorie guide → for breed-specific feeding amounts and ideal body condition targets.
Puppy Weight Chart — Small Breeds (10–25 lbs Adult)
Small breeds follow nearly the same clock as toys — most reach adult weight by 10–12 months — but they carry more structural variety. A long-backed Dachshund and a compact French Bulldog grow into very different bodies, and both need watching for different reasons.
| Age | Beagle (9–11 kg) | French Bulldog (8–14 kg) | Corgi (12–15 kg) | Dachshund (7–14 kg) | Cavalier King Charles (5–8 kg) |
|---|---|---|---|---|---|
| 8 weeks | 3–5 lbs | 4–6 lbs | 4–6 lbs | 3–5 lbs | 3–5 lbs |
| 3 months | 7–10 lbs | 8–13 lbs | 8–12 lbs | 6–10 lbs | 7–10 lbs |
| 4 months | 10–14 lbs | 11–18 lbs | 11–16 lbs | 8–14 lbs | 9–14 lbs |
| 6 months | 14–20 lbs | 15–25 lbs | 16–24 lbs | 11–20 lbs | 13–18 lbs |
| 9 months | 18–24 lbs | 16–28 lbs | 20–30 lbs | 14–28 lbs | 15–18 lbs |
| 12 months (adult) | 20–24 lbs | 16–28 lbs | 25–30 lbs | 16–32 lbs | 13–18 lbs |
How to use this table:
- Small breeds reach adult weight by 10–12 months.
- French Bulldogs and Dachshunds are prone to obesity — monitor body condition closely, because extra weight stresses a Frenchie's airway and a Dachshund's spine.
- Corgis can continue filling out (gaining muscle) up to 18 months even after skeletal growth stops — don't mistake healthy muscle gain for fat, and don't mistake fat for "still growing."
See the Beagle weight & calorie guide → and the French Bulldog weight & calorie guide → for exact daily calorie targets as your puppy moves through each growth stage.
Puppy Weight Chart — Medium Breeds (25–55 lbs Adult)
Medium breeds are the middle children of the growth world — fast enough that you'll see weekly changes, slow enough that nutrition mistakes have time to compound. Most reach skeletal maturity between 12 and 16 months and settle at adult weight by 12–18 months.
| Age | Border Collie (14–20 kg) | Australian Shepherd (18–29 kg) | Bulldog (18–23 kg) | Cocker Spaniel (12–15 kg) | Standard Schnauzer (14–20 kg) |
|---|---|---|---|---|---|
| 8 weeks | 5–8 lbs | 6–10 lbs | 8–12 lbs | 5–8 lbs | 6–9 lbs |
| 3 months | 10–16 lbs | 13–22 lbs | 15–25 lbs | 10–16 lbs | 12–18 lbs |
| 4 months | 15–24 lbs | 20–33 lbs | 22–38 lbs | 14–22 lbs | 17–26 lbs |
| 6 months | 22–35 lbs | 30–50 lbs | 35–48 lbs | 20–30 lbs | 25–38 lbs |
| 9 months | 28–42 lbs | 38–58 lbs | 40–50 lbs | 24–34 lbs | 30–42 lbs |
| 12 months | 31–44 lbs | 40–64 lbs | 40–50 lbs | 26–34 lbs | 33–44 lbs |
| 18 months (adult) | 31–44 lbs | 40–65 lbs | 40–50 lbs | 26–34 lbs | 30–45 lbs |
How to use this table:
- Medium breeds reach adult weight by 12–18 months.
- Border Collies and Australian Shepherds continue developing muscle mass past 12 months — a lean, athletic 14-month-old may still be "filling out" legitimately.
- Bulldogs grow slowly and are done growing by 12 months despite their medium build.
- After 12 months, weight should stabilize. Increases after this point are likely fat, not growth — adjust portions before it becomes a pattern.
See the Border Collie weight & calorie guide → for activity-adjusted calorie needs.
Puppy Weight Chart — Large & Giant Breeds (55+ lbs Adult)
This is where growth management becomes a health issue, not just a curiosity. Large and giant breed puppies grow for up to 24 months, and the rate of that growth directly affects their lifetime joint health. A Great Dane can gain 100+ lbs in its first year — how it gains that weight matters enormously.
| Age | Golden Retriever (25–34 kg) | Labrador (25–36 kg) | German Shepherd (22–40 kg) | Great Dane (45–80 kg) | Kangal (40–70 kg) |
|---|---|---|---|---|---|
| 8 weeks | 10–15 lbs | 10–15 lbs | 12–18 lbs | 15–22 lbs | 15–25 lbs |
| 3 months | 20–30 lbs | 22–33 lbs | 25–40 lbs | 35–55 lbs | 35–55 lbs |
| 4 months | 30–42 lbs | 33–48 lbs | 38–55 lbs | 55–80 lbs | 55–85 lbs |
| 6 months | 40–55 lbs | 45–60 lbs | 50–66 lbs | 75–105 lbs | 75–115 lbs |
| 9 months | 50–65 lbs | 55–72 lbs | 60–80 lbs | 95–130 lbs | 100–145 lbs |
| 12 months | 55–70 lbs | 60–78 lbs | 66–88 lbs | 110–155 lbs | 120–160 lbs |
| 18 months | 60–75 lbs | 65–80 lbs | 70–95 lbs | 120–170 lbs | 130–175 lbs |
| 24 months (adult) | 55–75 lbs | 55–80 lbs | 50–90 lbs | 110–175 lbs | 90–150 lbs |
How to use this table:
- Large breeds reach adult weight by 18–24 months. Don't rush it.
- Giant breeds grow the fastest in absolute terms but slowest relative to adult size — a Great Dane at 6 months looks enormous but is only about two-thirds done.
- Critical: Large/giant breed puppies should NOT be fed to grow as fast as possible. Overfeeding causes developmental orthopedic diseases (hip dysplasia, osteochondrosis). Feed a large-breed puppy formula with controlled calcium/phosphorus.
- Great Danes reach their maximum height by 12 months but continue filling out — gaining chest depth and muscle — until 24 months.
- Kangals and other livestock guardian breeds mature slowly, mentally and physically. Expect adolescent behavior well into the second year.
See the Golden Retriever weight & calorie guide →, the Labrador weight & calorie guide →, and the Kangal weight & calorie guide → for stage-by-stage feeding plans built around safe growth rates.
How to Predict Your Puppy's Adult Weight
The tables above show you the destination. This formula helps you predict it before you get there — useful for choosing the right crate size, budgeting for food, or simply settling the "how big will she get?" debate at the dog park.
The Puppy Weight Predictor Formula
| Size Category | Formula | Example |
|---|---|---|
| Toy / Small | Weight at 12 weeks × 2 | 3 lbs at 12 weeks → ~6 lbs adult |
| Medium | Weight at 16 weeks × 2.5 | 20 lbs at 16 weeks → ~50 lbs adult |
| Large | Weight at 6 months × 1.33 | 45 lbs at 6 months → ~60 lbs adult |
| Giant | Weight at 6 months × 1.5 | 80 lbs at 6 months → ~120 lbs adult |
Alternative simple method: Double the weight at 14–16 weeks for small breeds; double at 5–6 months for large breeds. Less precise, but easy to do in your head.
Important caveats:
- Mixed breeds: Estimate based on the larger parent breed's growth pattern. If you don't know the parents, use the size category your puppy's current trajectory points to.
- Neutering/spaying slightly increases adult weight (by ~5–10%) if done before maturity, because sex hormones play a role in growth plate closure.
- Nutrition plays a role — overfeeding can push a puppy above its genetic potential, and that's extra fat, not extra dog.
- These formulas are estimates — actual adult weight may vary ±10%. Genetics, litter size, and early nutrition all shift the outcome.
The formula works best as a range, not a promise. Plot your puppy's weight monthly, compare it to the breed table above, and the trend line will tell you more than any single calculation.
Puppy Growth Milestones by Month
Weight is only one dimension of growth. Teeth, behavior, and calorie needs all change on their own schedule — and knowing what's coming next makes each phase far easier to manage.
| Age | Physical Milestone | Behavioral Milestone | Nutrition Note |
|---|---|---|---|
| 8 weeks | Fully weaned; can eat solid food | Ready for new home; bonding period | Puppy food (AAFCO "growth" labeled) 3–4 meals/day |
| 3 months | Baby teeth fully in; starting teething | Vaccination series; socialization window peak | 3 meals/day; large-breed formula if applicable |
| 4 months | Baby teeth falling out; adult teeth coming | House training progressing; teething chewing | May eat less during teething — normal |
| 6 months | Adult teeth mostly in; sexual maturity possible | "Teenage" phase — testing boundaries | Transition to 2 meals/day; monitor weight closely |
| 9 months | Near adult height (small breeds); still growing (large) | Increased independence; may ignore commands | Calorie needs peak for large breeds |
| 12 months | Small/medium breeds near adult weight | Adult behavior emerging | Small breeds: transition to adult food. Large breeds: stay on puppy food |
| 18 months | Large breeds approaching adult weight | Fully mature emotionally | Large breeds: transition to adult food |
| 24 months | Giant breeds at adult weight | Fully mature | Giant breeds: transition to adult food at 18–24 months |
Two practical takeaways: the 6-month "teenage" phase is when most owners accidentally overfeed (the puppy looks grown but still has puppy energy needs), and the switch to adult food should follow skeletal maturity — not the calendar date of the first birthday.
Growth Problems: When to Worry
Most growth variation is normal. These four patterns are not.
- Growing too fast (large/giant breeds): Overfeeding leads to developmental orthopedic diseases. Large-breed puppies should grow at a STEADY rate, not as fast as possible. Warning signs: swollen joints, limping, reluctance to exercise.
- Growing too slow: May indicate parasites, malnutrition, portosystemic shunt (liver), or other congenital issues. If your puppy consistently falls below the low end of the range for 3+ weeks, see your vet.
- Uneven growth: Front legs growing faster than back (common in large breeds) — usually normalizes on its own. But persistent lameness warrants x-rays.
- Sudden weight loss: Parasites (giardia, worms), infection, or dietary change stress. Vet visit if lasting more than 24 hours.
⚠️ Large breed puppy rule: Never free-feed a large or giant breed puppy. Measure every meal. A puppy that grows too fast is at significantly higher risk of hip dysplasia and osteochondrosis. Slow and steady wins.
A weekly weigh-in habit catches all four problems early. Same scale, same time of day, before a meal — log the number and compare it against the breed tables above. Bring that log to every puppy vet visit; it turns a vague concern into actionable data.

Frequently Asked Questions
How big will my puppy get?
You can estimate your puppy's adult weight using size-specific formulas. For toy and small breeds, double the weight at 12 weeks. For medium breeds, multiply the weight at 16 weeks by 2.5. For large breeds, multiply the weight at 6 months by 1.33. For giant breeds, multiply the weight at 6 months by 1.5. For example, a Golden Retriever puppy weighing 45 lbs at 6 months will likely reach about 60 lbs as an adult. These are estimates and can vary ±10%.
When do puppies stop growing?
It depends on breed size. Toy breeds (Chihuahua, Pomeranian) stop growing by 8–10 months. Small breeds (Beagle, French Bulldog) stop by 10–12 months. Medium breeds (Border Collie, Bulldog) stop by 12–18 months. Large breeds (Golden Retriever, German Shepherd) stop by 18–24 months. Giant breeds (Great Dane, Mastiff, Kangal) can continue growing until 24 months. Note: stop growing means skeletal maturity — dogs may continue gaining muscle mass after this.
How much should a puppy weigh at 3 months?
It varies by breed. A 3-month-old Chihuahua weighs 1–2 lbs. A 3-month-old Beagle weighs 7–10 lbs. A 3-month-old Golden Retriever weighs 20–30 lbs. A 3-month-old Great Dane weighs 35–55 lbs. Use a breed-specific growth chart to track your puppy's weight against expected ranges. If your puppy consistently falls below or above the range for 3+ weeks, consult your veterinarian.
Should I be concerned if my puppy is growing too fast?
Yes, especially for large and giant breeds. Growing too fast increases the risk of developmental orthopedic diseases like hip dysplasia and osteochondrosis. Large breed puppies should be fed a large-breed puppy formula with controlled calcium and phosphorus levels. Never free-feed a large breed puppy — measure every meal. A puppy that gains weight too quickly is more likely to develop joint problems than one that grows at a steady, moderate pace.
How do I know if my puppy is at a healthy weight?
Use the Body Condition Score (BCS) system. A healthy-weight puppy should have: visible ribs when you run your hands along their sides (but not visible from a distance); a visible waist when viewed from above; and a tucked-up abdomen when viewed from the side. Puppies should look lean — it's normal and healthy to see some rib definition. A round, pudgy puppy is overweight and at risk for joint problems, especially in large breeds. Use our free BCS Assessment tool to check.
