Beagle growth chart
The AKC standard gives 13 inches & under: up to 9.1 kg, 13-15 inches: 9.1 to 13.6 kg, and up to 33 cm at the shoulder. That places the Beagle in the medium size category, so its growth follows that curve, scaled to this breed’s own published weight rather than to a category average.
What the breed standard says
| Measure | Metric | As the source states it |
|---|---|---|
| Weight, 13 inches & under | up to 9.1 kg | under 20 pounds (13 inches & under), 20-30 pounds (13-15 inches) |
| Weight, 13-15 inches | 9.1 to 13.6 kg | under 20 pounds (13 inches & under), 20-30 pounds (13-15 inches) |
| Height | up to 33 cm | 13 inches & under, 13-15 inches |
| Height | 33 to 38.1 cm | 13 inches & under, 13-15 inches |
| Life expectancy | 10 to 15 years | 10-15 years |
| AKC popularity | Ranks 7 of 210 | AKC breed registration statistics |

Beagle weight by age
Percentages are the medium category curve. Weights are those percentages applied to this breed’s published adult range, so the middle column is a Beagle at the centre of its standard.
| Age | Percent grown | Expected weight | Range across the standard |
|---|---|---|---|
| 12 weeks (2.8 months) | 36% | 4.1 kg (9 lb) | 3.3 to 4.9 kg |
| 16 weeks (3.7 months) | 45% | 5.2 kg (11 lb) | 4.1 to 6.2 kg |
| 20 weeks (4.6 months) | 57% | 6.5 kg (14 lb) | 5.2 to 7.7 kg |
| 26 weeks (6.0 months) | 71% | 8 kg (18 lb) | 6.4 to 9.6 kg |
| 34 weeks (7.8 months) | 82% | 9.3 kg (21 lb) | 7.5 to 11.2 kg |
| 43 weeks (9.9 months) | 88% | 10 kg (22 lb) | 8 to 12 kg |
| 52 weeks (12.0 months) | 90% | 10.3 kg (23 lb) | 8.2 to 12.3 kg |
| 78 weeks (1.5 years) | 96% | 10.9 kg (24 lb) | 8.7 to 13.1 kg |
| 104 weeks (2.0 years) | 100% | 11.3 kg (25 lb) | 9.1 to 13.6 kg |
When a Beagle finishes growing
- Half adult weight at around 5 months.
- 90% of adult weight at around 12 months.
- Essentially finished by around 24 months.
- Senior from about 8 years, following AAHA life stage guidance, which sets senior status by proportion of expected lifespan rather than a fixed birthday.
Height finishes before weight. A Beagle that has stopped getting taller will still be filling out through the chest and shoulders for months afterwards, which is why an apparently full-grown dog can carry on gaining.
Feeding a Beagle puppy
At six months a male at the middle of the standard weighs about 8 kg and needs roughly 668 kcal a day. A grown one at 11.3 kg needs about 866 kcal. Both come from Merck’s resting energy formula with the growth multiplier applied.
Across a whole first year that adds up to a real number, and the puppy cost calculator works it out month by month for this size of dog.
Work out actual portions with the feeding calculator above, or the daily figure alone with the how many calories does my puppy need. Both need the energy density from your bag, because two foods of the same weight can differ by hundreds of calories.
How much to trust this chart
- The curve is the size category, not the breed. Salt et al. grouped dogs by adult bodyweight because that is what predicts growth. There is no Beagle dimension in the source data, and any page claiming a breed-specific curve from it is claiming more than it has.
- The weights are the breed, though. They are the category percentages applied to the AKC published range, so the table ends where this breed actually ends. Our guide to whether breed growth charts are really breed specific works through what that does and does not buy you.
- A breed standard is a target, not a census. Plenty of healthy dogs sit outside it. Steady progress along one line beats hitting any particular number.
- Mixes are a different question. If your puppy is part Beagle, the mixed breed puppy growth calculator will do better than this page.
Frequently asked questions
How big will my Beagle get?
The AKC standard gives 13 inches & under: up to 9.1 kg, 13-15 inches: 9.1 to 13.6 kg. The source states it as under 20 pounds (13 inches & under), 20-30 pounds (13-15 inches).
Height runs up to 33 cm at the shoulder.
Those are the breed standard, not a prediction for your dog. A Beagle at the top of the range and one at the bottom are both entirely normal, and the how big will my puppy get calculator will narrow it down from your puppy's current weight.
When does a Beagle stop growing?
Around 24 months for practical purposes, with the curve passing 90% of adult weight at about 12 months.
That is the medium category curve rather than a measurement on this breed specifically. Bigger dogs finish later: filling out in the chest and shoulders carries on for months after height has stopped, so a dog that looks finished may still be gaining.
What should a Beagle puppy weigh at 6 months?
About 8 kg (18 lb) for a male at the middle of the breed standard. That is 71% of adult weight.
The full table above gives the rest of the first two years. Treat the figures as the centre of a range, not a target: a puppy tracking steadily along its own line matters far more than hitting a number on a given week.
How much should a Beagle eat?
At six months, roughly 668 kcal a day, using the Merck resting energy formula with the growth multiplier. A grown one at 11.3 kg needs about 866 kcal.
Turn that into portions with the puppy feeding calculator, which needs the energy density printed on your bag, because two foods at the same weight can differ by hundreds of calories.
Is this chart specific to the Beagle?
Half of it is, and it is worth knowing which half. The percentages come from the medium size category in Salt et al. 2017, which has no breed dimension in it at all. Any breed in this category shares that curve.
The weights are this breed's, scaled to the AKC published adult range. That is a more modest claim than a breed-specific curve, and it is the one the data actually supports.
