ABSTRACT
The aim of the present study was to develop the first life tables for the dog population of the Autonomous City of Buenos Aires by constructing life expectancy tables. Data on canines received for final disposal at the Luis Pasteur Zoonosis Institute of the Autonomous City of Buenos Aires from January 2018 to December 2021 were used to prepare the life tables. Of the 11,429 dogs that died in that period, the overall life expectancy at birth was 11.88 years (95% CI = 11.37-12.39). There was no difference in life expectancy at birth by sex or by pure versus cross breeds. According to neuter status, life expectancy at birth in neutered (13.98 years) was significantly higher than in entire (11.46 years) (p-value = 0.00001). Life tables varied according to the breed studied, with the Pekingese having the highest life expectancy at birth 16.42 years (95% CI: 15.87-16.98), and the Pit bull having the lowest life expectancy at birth 10.13 years (95% CI: 9.58-10.68). The current study provides useful information for veterinary professionals and pet owners and is a valuable tool for planning and developing effective health policies.
