"Diverse Life Expectancies Among Dog Breeds"
A study of almost 600,000 British dogs from over 150 breeds revealed "spectacular" variations in lifespans, with small breeds generally living longer than larger ones. The Lancashire Heeler and Tibetan Spaniel were among the longest-lived, while the Caucasian Shepherd had the shortest lifespan. Contrary to previous findings, purebred dogs were found to live slightly longer than crossbred dogs on average. The study aims to help dog owners and welfare groups make informed decisions and improve the lives of canine companions, highlighting specific populations that need attention.
