The Rottweiler, and What the Published Record Shows
This page is not veterinary advice. Paw Multiverse is not a veterinary practice. We cannot examine, diagnose or treat your animal. There are no doses here, no portion sizes, no feeding amounts and no treatment steps, on purpose. If your pet has eaten something you are worried about, or has changed in a way you cannot explain, ring your vet or your nearest emergency clinic and let them decide. Full disclaimer.
This page exists because two of our cost pages said out loud that it did not. It is built on two documents and nothing else: the Royal Kennel Club breed standard, and the VetCompass study of Rottweilers in UK first opinion practice.
Those two documents disagree with each other about something important, and that disagreement is the most useful thing on this page.
What the breed standard asks for
The Royal Kennel Club standard, last updated 1 April 2025, describes an “above average size, stalwart dog”, with a “correctly proportioned, compact and powerful form, permitting great strength, manoeuvrability and endurance”.
On character it says the “appearance displays boldness and courage”, that the dog is “self-assured and fearless”, and that a “calm gaze should indicate good humour”. On temperament it is explicit: “good natured, not nervous, aggressive or vicious; courageous, biddable, with natural guarding instincts”.
On size it gives a height range at the shoulder for dogs and for bitches, and says height should be considered in relation to overall appearance. Source: Royal Kennel Club, Rottweiler breed standard, last updated 1 April 2025 (read 5 Aug 2026).
Read that temperament clause again, because the next section is about a number that sits directly against it.
What Rottweilers are actually brought to the vet for
VetCompass looked at 5,321 Rottweilers, 1.17 per cent of a study population of 455,557 dogs attending 304 clinics. The four most commonly recorded specific disorders were:
- aggression, 7.46 per cent (95% CI 6.40 to 8.64)
- overweight or obesity, 7.06 per cent (95% CI 6.02 to 8.21)
- otitis externa, 6.14 per cent (95% CI 5.18 to 7.23)
- degenerative joint disease, 4.69 per cent (95% CI 3.84 to 5.66)
Source: O’Neill et al., Rottweilers under primary veterinary care in the UK: demography, mortality and disorders, Companion Animal Health and Genetics (read 5 Aug 2026). The confidence intervals are printed because a prevalence without one is a rumour.
The aggression finding, read carefully
The most commonly recorded disorder in this breed, in the study, is aggression. The breed standard says the dog should not be aggressive. Both statements are accurate and they are not measuring the same thing.
What the study counted is a clinical record made by a veterinary professional during a consultation. That happens when aggression is presented as a problem, or is observed in the consulting room, or is written down as a handling note. It is not a survey of temperament and it is not a rate of bites. A breed that is large, strong and guarding by design will have aggression recorded more readily than a small breed doing the same thing, because the consequence of it is larger.
The study also found a sex difference: “male Rottweilers had higher prevalence than females for aggression (9.36% versus 5.47%, P = 0.001)”.
So the honest reading is neither that the standard is wrong nor that the breed is dangerous. It is that this is the breed where the gap between the written temperament and the recorded clinical reality is widest, and that anybody taking one on should know the number exists and know exactly what it counts.
This site gives no training advice, no behaviour programme and no handling instruction, here or anywhere. Behaviour in a large guarding breed is a matter for a qualified behaviourist working with your vet, and it is one of the few areas where getting it from a website is actively worse than getting nothing.
Longevity, and how the study says they die
Median longevity overall was 9.0 years (IQR 7.2 to 10.5, range 0.0 to 17.0). The sexes differ: females had a median of 9.5 years (IQR 7.8 to 11.0), males 8.7 years (IQR 6.8 to 10.1). Source: O’Neill et al., Rottweilers under primary veterinary care in the UK: demography, mortality and disorders, Companion Animal Health and Genetics (read 5 Aug 2026).
The interquartile range is the part worth sitting with. Half the dogs in this dataset died between 7.2 and 10.5 years. A prospective owner planning around a decade is planning around the middle of the distribution, not around a promise.
The most common causes of death were neoplasia at 33.0 per cent, inability to stand at 16.0 per cent, and mass-associated disorder at 7.1 per cent.
Put those together with the disorder list and a shape appears. Neoplasia is the single largest cause of death by a wide margin, and inability to stand is the second, which sits alongside degenerative joint disease in the disorder table. This is a breed where the expensive and difficult years are the last two or three, and where the thing that ends it is more often a mass than a joint.
Rottweiler, as the VetCompass study records it
==============================================
study population 5,321 of 455,557 dogs, 304 clinics
median longevity 9.0 years (IQR 7.2 to 10.5)
females 9.5 years (IQR 7.8 to 11.0)
males 8.7 years (IQR 6.8 to 10.1)
most recorded aggression 7.46%
overweight/obesity 7.06%
otitis externa 6.14%
degenerative joint 4.69%
causes of death neoplasia 33.0%
inability to stand 16.0%
mass associated 7.1% Bodyweight, and a figure we will not turn into a target
The study reports a median male adult bodyweight of 48.5 kg (IQR 43.0 to 54.0) and a median female of 41.5 kg (IQR 37.0 to 46.4). Source: O’Neill et al., Rottweilers under primary veterinary care in the UK: demography, mortality and disorders, Companion Animal Health and Genetics (read 5 Aug 2026).
Those are descriptions of a population of dogs that were brought to a vet. They are not a target, they are not a healthy weight, and they are not something to weigh your dog against. Overweight and obesity is the second most commonly recorded disorder in this same breed, in this same dataset, which means the median is measured across a population that includes a lot of overweight dogs.
This site publishes no weight target and no body condition score for any animal. If you want to know whether your dog is the right weight, the person to ask has their hands on the dog.
What we could not source
Written down rather than left as a gap. All attempted on 5 August 2026.
- No entry for the Rottweiler in the Teng et al. life tables for UK companion dogs, so this page carries no life expectancy at age zero for the breed and no comparison against other breeds on that measure.
- No UK insurance claims dataset broken down by breed, and no published figure for the proportion of UK dogs that are insured.
- No published health screening scheme results specific to UK Rottweilers that we could reach.
- No published study of Rottweiler behaviour outside the clinical record, so the aggression figure above stands alone and is not corroborated or contradicted by anything we could find.
- The Association of British Insurers page on types of pet insurance cover loads but its list did not render in any fetch. The wording obtained on 4 August 2026 is quoted on our pet insurance guide.
