How much does a Rottweiler weigh? In UK vet records, the typical adult male weighed about 48.5kg and the typical adult female about 41.5kg. Rottweiler weight isn’t given in the Royal Kennel Club’s breed standard, which sets heights instead: 63–69cm at the shoulder for males and 58–64cm for females. No UK source publishes a month-by-month weight chart for Rottweiler puppies.
We haven’t owned a Rottweiler, so this guide draws on the Royal Kennel Club’s breed standard, Royal Veterinary College (RVC) VetCompass research and PDSA rather than personal experience. Where UK sources say nothing, we’ve said so.
Before you weigh: PDSA says it’s best to use your dog’s shape as well as the scales to check they’re a healthy weight. Checking their shape regularly also shows you whether they’ve gained or lost weight.

| Weight in the breed standard | Not given | Not given | Royal Kennel Club breed standard |
| Typical adult weight | 48.5kg | 41.5kg | RVC VetCompass (UK vet records, 2013) |
| Middle half of adult dogs | 43–54kg | 37–46kg | RVC VetCompass (UK vet records, 2013) |
| Average weight for the breed | 35–60kg (males and females together) | 35–60kg (males and females together) | PDSA |

The breed standard describes the ideal Rottweiler, and the Royal Kennel Club notes that a dog might be larger or smaller than the sizes it gives. The typical weights are medians: the middle weight of adult Rottweilers, aged 18 months or more, in UK vet records from 2013.
Rottweiler weight chart in kg: what UK Rottweilers weighed
The RVC’s VetCompass study looked at the records of Rottweilers seen at UK vet practices in 2013. This chart shows how adult males and females, aged 18 months or more, were spread across weight bands. Each band runs up to, but not including, the next number.
| Adult weight | Males | Females |
|---|---|---|
| Under 30kg | About 1 in 100 | About 1 in 30 |
| 30–40kg | About 1 in 8 | About 1 in 3 |
| 40–50kg | About 4 in 10 | Almost half |
| 50–60kg | About 1 in 3 | About 1 in 10 |
| 60–70kg | About 1 in 12 | About 1 in 60 |
| 70kg or more | About 1 in 80 | About 1 in 1,000 |
Most adult males weighed between 40 and 60kg, and most adult females between 30 and 50kg. These are the weights vets recorded, overweight dogs included, so they show what UK Rottweilers weighed, not what yours should weigh. Your dog’s shape is the better guide to that, and we cover how to check it below.
How tall Rottweilers grow at the shoulder
The Royal Kennel Club’s breed standard gives a height range for each sex, measured at the shoulder: 63–69cm for males and 58–64cm for females. It adds that height should always be considered alongside the dog’s general appearance.
As with weight, these figures describe the ideal rather than a promise. Your Rottweiler may end up a little taller or shorter.
If you’re comparing Rottweilers with similar-sized breeds, our Rottweiler vs German Shepherd and Doberman vs Rottweiler guides set the breed standards side by side.
When do Rottweilers stop growing?
No UK source we found gives an age at which Rottweilers in particular stop growing. PDSA’s general guidance is that most dogs are fully grown by one year of age, but larger breeds, such as Labradors, Dobermans and Great Danes, can take as long as 18 months to 2 years to reach full size. PDSA lists the Rottweiler as a large breed, so ask your vet how long to expect your puppy to keep growing.
Until a puppy is fully grown, its joints and growth plates are still developing. PDSA warns that too much exercise during this time, especially high-impact exercise, can damage them and lead to problems such as early arthritis and hip dysplasia. Carrying extra weight also puts pressure on growing joints.
Food matters too. PDSA’s vets say that, as a general rule, large and giant breeds need puppy food until around 18 months. The right time to switch depends on your dog, so check with your vet if you’re not sure.
Growing puppies: PDSA advises avoiding long walks, hikes, running and cycling until your puppy is fully grown, and building their fitness up slowly. Play, short walks and training are better ways to keep a young Rottweiler active.
Why we don’t give a puppy weight chart
Many websites publish month-by-month Rottweiler weight charts, and their figures don’t agree. We couldn’t find one from the Royal Kennel Club, PDSA, Dogs Trust, Blue Cross or UK vet-records research, so we haven’t included one.
Instead, weigh your puppy regularly, check their shape using the steps below, and ask your vet whether they’re growing at a healthy rate.
How to check your Rottweiler is a healthy weight
PDSA recommends a body condition check, which you can do at home by looking at and feeling your dog. PDSA’s body condition score guide sets out five steps:
- Run your hands along your dog’s sides. You should be able to feel their ribs with a light touch.
- Run your hands along their back. You should be able to feel the spine and hip bones without being able to see them.
- Gently feel the base of their tail. There shouldn’t be a build-up of fat.
- Feel under their tummy. It should go in, not bulge out.
- Look at them from the side and from above. You should be able to see a waist.
Repeating these checks regularly will show you if your Rottweiler has gained or lost weight. Being overweight was one of the problems UK vets recorded most often in Rottweilers in the VetCompass study, and our Rottweiler vs German Shepherd guide covers those health findings in more detail.
Ask your vet: PDSA says your vet is the best person to ask if you’re not sure whether your dog is putting on weight. They can weigh your Rottweiler and check their shape with you.
Neutering and your Rottweiler’s weight
Neutering changes how much food a dog needs. PDSA says a neutered dog needs about 30% fewer calories, so ask your vet about portion sizes after the operation and keep checking your Rottweiler’s shape.
For large breeds, PDSA says your vet may advise waiting to neuter until the growth plates have closed. Our male vs female dogs guide covers neutering timing in more detail.
Final thoughts: what a healthy Rottweiler weight looks like
In UK vet records, adult male Rottweilers typically weighed about 48.5kg and females about 41.5kg. The right weight for your dog, though, is the one where their shape passes PDSA’s checks.
- If you want a number, use the UK vet-records figures as a rough guide, not a target.
- If you have a puppy, weigh them regularly, check their shape and ask your vet about growth, food and exercise until they’re fully grown.
- If your Rottweiler has been neutered, ask your vet about cutting their food, as PDSA says they need about 30% fewer calories.
- If you’re not sure whether your dog is a healthy weight, ask your vet.

Frequently Asked Questions
How much does an adult Rottweiler weigh?
In UK vet records, the typical adult male Rottweiler weighed about 48.5kg and the typical female about 41.5kg. PDSA gives an average range of 35–60kg for the breed. The breed standard doesn’t give a weight, so check your dog’s shape rather than aiming for a number.
Do Rottweilers count as a large breed?
Yes. The Royal Kennel Club and PDSA both class the Rottweiler as a large breed. The breed standard gives a height of 63–69cm at the shoulder for males and 58–64cm for females, and adult males in UK vet records typically weighed about 48.5kg.
What should my Rottweiler puppy weigh at 6 months?
No UK source we found gives a weight for Rottweiler puppies by age, and the charts online don’t agree. Weigh your puppy regularly, check their shape using PDSA’s body condition steps, and ask your vet whether they’re growing at a healthy rate.
Are there giant Rottweilers?
The Royal Kennel Club recognises one Rottweiler breed, and its standard gives heights, not weights. In UK vet records, about 1 in 80 adult males weighed 70kg or more. A heavier dog isn’t necessarily a healthier one, so check your Rottweiler’s shape, not just the scales.
Do female Rottweilers weigh less than males?
Usually, yes. In UK vet records, the typical adult female weighed about 41.5kg against about 48.5kg for males, a difference of around 7kg. The breed standard also gives females a lower height range: 58–64cm at the shoulder, against 63–69cm for males.
How much less should a neutered Rottweiler eat?
PDSA says a neutered dog needs about 30% fewer calories. That’s a general guide, so ask your vet how much to feed your Rottweiler after the operation, and keep checking their shape to make sure they aren’t putting on weight.
