Adult weight and size by breed, based on the cited sources, plus a personalised estimate for your puppy.
The calculation runs in your browser: we do not send or store any data about your dog.
How this page works
By breed: we show the male and female weight and height ranges using the source stated for each breed, the age at which growth usually ends, and which Robust crate fits that range. Each row states its source and the type of value shown. It may be an official range, an “ideal” or “desirable” weight the standard gives as a reference, or a typical range when no official body publishes a weight range.
By age and weight: enter your puppy's age and current weight to receive an adult-weight estimate based on data derived from the published growth curves (50th percentile of the WALTHAM™ Puppy Growth Charts, by size and sex). It is a guideline, not a veterinary prediction: the curves were created to monitor growth, not to predict adult weight from a single weigh-in. That is why the result includes a confidence level. You can repeat the calculation with new weigh-ins to update the guideline as your puppy grows.
How to read the result
The range shows where your dog's adult weight is likely to fall. The estimate is usually most reliable between four and ten months. Uncertainty increases in very young puppies, in mixed breeds with no information about the parents, and in giant breeds. For giant breeds there is no validated standard curve, so we use a guideline adaptation based on the published curves of five giant breeds. The percentage shows roughly what share of its estimated adult weight it has reached. This information does not replace veterinary advice. Book a check-up if your puppy loses weight, fails to gain weight for several weeks or gains weight unusually quickly.
Table: adult weight and size of the 63 breeds
Males and females separately. The source is shown in every row (FCI, AKC, Royal Kennel Club, RSCE or typical range). ~ = approximate value: check the source shown for each row to see whether the value is ideal, desirable, average or typical. The “Growth ends” column is general veterinary guidance by size; those ages are not part of the standards.

Two terms worth knowing
Height at the withers is the distance from the ground to the withers, the highest point of the dog's back, where the neck meets the body. It is the official measure of a dog's size: when a standard says “62 cm”, it always means the withers, not the top of the head.
A breed standard is the official document that describes what the breed should be like: size, weight, proportions, coat and temperament. Standards are published by the FCI (Fédération Cynologique Internationale) and the major national kennel clubs, and they are the primary source for the ranges on this page.
When to see the vet
The calculator only offers guidance; your vet should assess any concerns and oversee the follow-up. Book an appointment if your puppy loses weight, goes several weeks without gaining weight, gains weight at a rate out of proportion to its size, or if it experiences persistent diarrhoea or vomiting, becomes lethargic, or has a very low or very high body condition score. And in large and giant breeds, growth rate and feeding deserve professional monitoring: growing too fast is also a problem.
Where these figures come from (and which part is our own work)
· Weights and heights by breed: official FCI standards (fci.be) and, where the FCI standard only gives the height, the official AKC or Royal Kennel Club (UK) breed page. Data for the Ratonero Bodeguero Andaluz come from the 2022 RSCE standard. Each row of the table states its source; weights with no published official reference are shown as typical ranges.
· Growth curves: the 50th percentile of the official WALTHAM™ Puppy Growth Charts (based on Salt et al. 2017, PLOS ONE). The underlying study used age and weight data from more than six million young dogs; the resulting charts cover five adult-size categories and are split by sex. Those charts were published to monitor growth; turning them into an adult-weight estimate is Robust's own guideline adaptation, not a clinically validated method — which is why we show a confidence level instead of promising precision. For puppies aged two months and for the giant category we use the equation published by Hawthorne et al. (2004, Journal of Nutrition).
· Differences between males and females: Andersson et al. 2023 (Scientific Reports): in 114,568 dogs across 72 breeds, males were significantly heavier in 54 of those breeds.
· Age at completion of growth: general veterinary guidance by size (not part of the standards).

Frequently asked questions
When does a dog stop growing?
It depends on size: small breeds finish growing in height between 8 and 12 months, medium breeds at around 12 months, large breeds between 12 and 18, and giant breeds can continue until 18–24 months. Dogs usually reach their adult weight slightly later than their adult height, while full muscle development takes longer still.
Do big paws mean a puppy will grow into a big dog?
Not necessarily. Paw size can be a clue, but there is no reliable formula based on paws alone. A puppy's current age and weight, together with its breed or the size of its parents, are better guides.
What if my puppy is a mixed breed?
Use the age-and-weight calculator, which does not require you to know the breed. If you know the parents, their size (both of them, not just one) is the best clue; if not, you can repeat the calculation with new weigh-ins to update the estimate. In mixed breeds with no information about the parents, the result should be interpreted with extra caution.
Do males weigh more than females?
In most breeds, yes: in a study of more than 114,000 dogs across 72 breeds, males were heavier in 54. That is why this page always gives the two ranges separately and the calculator asks for the sex.
Is the estimate always right?
No. No calculator can guarantee an exact figure. This is a guideline based on published growth curves, not a veterinary prediction: each puppy's genetics, diet and health can affect the result. Regular weigh-ins at your veterinary practice provide the most reliable guide.
Which crate size should I buy while my dog is still a puppy?
For medium, large and giant breeds, it makes sense to choose a crate that will suit the dog at its adult size from the start; that avoids having to buy a second one. During the first months, the interior space can be partitioned to help with toilet training. A dedicated puppy divider for Robust crates will be available from January 2027.
In short
- There is no exact figure: the breed gives the range (males and females separately) and each dog's individual traits may mean that its adult weight falls outside that interval.
- Small breeds finish growing at around 8–12 months; giants can continue until age two.
- Age, weight and sex can provide a useful estimate of adult weight, including for mixed-breed dogs, although with greater uncertainty.
- For medium, large and giant breeds: choose a crate that will suit the dog at its adult size from the start and temporarily partition the interior during the first months. A dedicated puppy divider will be available from January 2027.
- Regular weigh-ins at your veterinary practice provide the most reliable guide.
