Puppy Growth Chart Examples
These tables show how this site's five calculator curves translate an example adult weight into age-by-age values. They are model illustrationsânot targets that every healthy puppy should match.
Read the chart in the right direction
The calculator estimates adult weight from a puppy's measurement. The tables below do the reverse: they start with an assumed adult weight and multiply it by each curve fraction. Use them to understand the model, not to diagnose growth.
Why size groups have different timelines
Dogs do not all mature on the same schedule. Published studies have found meaningful differences in growth patterns among adult-size groups. That makes one ruleâsuch as doubling every dog's 16-week weightâtoo simplistic for a general calculator.
Our site uses separate toy, small, medium, large, and giant curves and interpolates smoothly between listed ages. The exact fractions are modeling assumptions documented on the methodology page. They are not copied clinical percentiles.
Toy example: 10 lb adult weight
If the adult dog eventually weighs 10 lb, this is the approximate path assumed by the site's toy curve. A real dog's measurements may be above, below, or cross this example over time.
| Age | Estimated Weight (lbs) |
|---|---|
| 8 Weeks | ~ 4 lbs |
| 12 Weeks | ~ 6 lbs |
| 16 Weeks | ~ 7 lbs |
| 24 Weeks | ~ 9 lbs |
| 36 Weeks | ~ 10 lbs |
| 52 Weeks (1 Year) | ~ 10 lbs |
Small example: 20 lb adult weight
If the adult dog eventually weighs 20 lb, this is the approximate path assumed by the site's small curve. A real dog's measurements may be above, below, or cross this example over time.
| Age | Estimated Weight (lbs) |
|---|---|
| 8 Weeks | ~ 6 lbs |
| 12 Weeks | ~ 9 lbs |
| 16 Weeks | ~ 12 lbs |
| 24 Weeks | ~ 16 lbs |
| 36 Weeks | ~ 18 lbs |
| 52 Weeks (1 Year) | ~ 20 lbs |
Medium example: 50 lb adult weight
If the adult dog eventually weighs 50 lb, this is the approximate path assumed by the site's medium curve. A real dog's measurements may be above, below, or cross this example over time.
| Age | Estimated Weight (lbs) |
|---|---|
| 8 Weeks | ~ 12 lbs |
| 12 Weeks | ~ 17 lbs |
| 16 Weeks | ~ 23 lbs |
| 24 Weeks | ~ 33 lbs |
| 36 Weeks | ~ 41 lbs |
| 52 Weeks (1 Year) | ~ 47 lbs |
| 65 Weeks (1 Year+) | ~ 50 lbs |
Large example: 80 lb adult weight
If the adult dog eventually weighs 80 lb, this is the approximate path assumed by the site's large curve. A real dog's measurements may be above, below, or cross this example over time.
| Age | Estimated Weight (lbs) |
|---|---|
| 8 Weeks | ~ 16 lbs |
| 12 Weeks | ~ 22 lbs |
| 16 Weeks | ~ 30 lbs |
| 24 Weeks | ~ 44 lbs |
| 36 Weeks | ~ 56 lbs |
| 52 Weeks (1 Year) | ~ 67 lbs |
| 65 Weeks (1 Year+) | ~ 74 lbs |
| 78 Weeks (1 Year+) | ~ 80 lbs |
Giant example: 130 lb adult weight
If the adult dog eventually weighs 130 lb, this is the approximate path assumed by the site's giant curve. A real dog's measurements may be above, below, or cross this example over time.
| Age | Estimated Weight (lbs) |
|---|---|
| 8 Weeks | ~ 21 lbs |
| 12 Weeks | ~ 30 lbs |
| 16 Weeks | ~ 40 lbs |
| 24 Weeks | ~ 59 lbs |
| 36 Weeks | ~ 75 lbs |
| 52 Weeks (1 Year) | ~ 94 lbs |
| 78 Weeks (1 Year+) | ~ 112 lbs |
| 104 Weeks (1 Year+) | ~ 130 lbs |
How to use repeated measurements
Use the same scale under similar conditions and record the date, age, unit, and any relevant context. Compare the longer-term direction rather than expecting a perfectly smooth weekly line. Our guide to weighing and tracking a puppy consistently provides a practical process.
Unexpected weight loss, failure to gain, a major body-condition change, poor appetite, persistent digestive signs, or lethargy calls for a licensed veterinarian. A model chart cannot determine the cause.
