The results of a questionnaire provided data about owners' perceptions of the cause of death of over 3000 British dogs. The mean age at death (all breeds, all causes) was 11 years one month, but in dogs dying of natural causes it was 12 years eight months. Only 8 per cent of dogs lived beyond 15, and 64 per cent of dogs died of disease or were euthanased as a result of disease. Nearly 16 per cent of deaths were attributed to cancer, twice as many as to heart disease. Neutered females lived… 
Average Life Expectancy, the Most Common Cause of Death and Illness of Giant Dog Breeds
The average lifespan in giant breed dogs was found to be 7.60 years and the most common cause of spontaneous death among giant breeds was gastric dilatation and torsion, especially in selected Mastiff type breeds of dogs.
Heart disease as a cause of death in insured Swedish dogs younger than 10 years of age.
Breed, age, and sex affect cardiac mortality in certain breeds of dogs, but no effects of month and geographic location were identified, which can assist clinicians in establishing diagnoses and breeders in defining priorities for preventative measures.
Do Female Dogs Age Differently Than Male Dogs?
This analysis suggests that the majority of apparent sex differences in the wider canine populations may be due to the effects of neutering, and suggests limited sex effects on either longevity or causes of death in the companion dog.
Exceptional longevity in pet dogs is accompanied by cancer resistance and delayed onset of major diseases.
The reduction in cancer mortality in oldest-old pet dogs mimics that seen in human centenarians and provides strong rationale for using this animal model to study comparative mechanisms of cancer resistance in the extreme aged.
Exploring mechanisms of sex differences in longevity: lifetime ovary exposure and exceptional longevity in dogs
Pet dogs are studied to show that lifetime ovary exposure, a factor not previously evaluated in women, is associated with exceptional longevity and introduce a conceptual framework for designing additional studies in pet dogs to define the ovary‐sensitive biological processes that promote healthy human longevity.
Mortality in over 350,000 Insured Swedish Dogs from 1995–2000: II. Breed-Specific Age and Survival Patterns and Relative Risk for Causes of Death
The age patterns for total and diagnostic mortality and for general causes of death (trauma, tumour, locomotor, heart and neurological) are presented for numerous breeds and decision-making at the population and individual level about health promotion efforts and treatment and prognosis of disease events are supported.
Mortality in over 350,000 Insured Swedish dogs from 1995–2000: I. Breed-, Gender-, Age- and Cause-specific Rates
This study presents data on over 350,000 insured Swedish dogs up to 10 years of age contributing to over one million dog-years at risk (DYAR) during 1995–2000, with detailed statistics on mortality that can be used in breed-specific strategies as well as for general health promotion programs.
Causes of death or reasons for euthanasia in military working dogs: 927 cases (1993-1996).
Although sexually intact male dogs were more numerous in the study population, castrated male dogs typically lived longer than spayed females or sexually intact males and were at increased risk for death attributable to neoplasia, behavior, and respiratory tract disease.


Variation in age at death of dogs of different sexes and breeds.

A retrospective study of necropsy data for 2,002 dogs showed that the mean age at death of neutered dogs of both sexes exceeded that of intact dogs, but the differences were not significant. A wide
Mortality in insured Swedish dogs: rates and causes of death in various breeds
Trauma, tumours and problems related to the locomotor system together accounted for more than 40 per cent of all deaths or euthanasias and provide baseline mortality data for further population-based studies on health and disease.
Comparative longevity of pet dogs and humans: implications for gerontology research.
The effect of breed and body weight on longevity in the pet dog was analyzed, and a method was developed to standardize the chronological age of dogs in terms of physiological time, using human year
[Life expectancy and cause of death in dogs. I. The situation in mixed breeds and various dog breeds].
The present study on life expectancy and cause of death is based upon data from 9,248 dogs, and dogs of mixed breeding tended not to differ from purebreds either in their life expectancy or in their cause ofdeath.
Cellular proliferative capacity and life span in small and large dogs.
It appears that within the domestic dogs the large body size is accompanied by shorter life span and, in the two largest breeds, decreased cellular growth potential.
Epidemiological studies on the expectation of life for dogs computed from animal cemetery records.
If the probability of dying for cats at early ages decreases, the fundamental pattern of dying curve for cats seems to be a similar figure of dogs.
Epidemiological study of blood pressure in domestic dogs.
The hypothesis that dogs, though classic model animals for hypertension, are resistant to its development found support from the modest increase in mean pressure values observed among dogs with renal disease, notably those with substantial reduction of glomerular filtration rate.
Reasons for the euthanasia of dogs and cats

As part of a survey of companion animal veterinary practices in England the records of 863 euthanased dogs and cats were studied, with a total of 478 were dogs and 385 cats.
Longevity, Genes, and Aging
Because of its complexity, the aging process takes us into the realm of integrative biology, and thus, biogerontology should prove instrumental in deciphering the functional and regulatory circuitry of the sequenced genome.
Oxidative Stress, Caloric Restriction, and Aging
Support for this hypothesis includes the following observations: (i) Overexpression of antioxidative enzymes retards the age-related accrual of oxidative damage and extends the maximum life-span of transgenic Drosophila melanogaster and (ii) Variations in longevity among different species inversely correlate with the rates of mitochondrial generation of the superoxide anion radical and hydrogen peroxide.
