A new study, titled "Longevity of companion dog breeds: those at risk from early death" published in Scientific Reports, analyzed over 580,000 British dogs from over 150 breeds and found that a bulldog may find its way to heaven earlier than a Border terrier.
The research aims to assist individuals planning to get a dog by helping them choose breeds associated with longer and healthier lives, utilizing data from over half a million dogs across the UK.

Dog Breeds With Longer and Shorter Lifespan
The recent analysis suggests that smaller dog breeds with elongated snouts, such as miniature dachshunds and shiba inus, tend to enjoy longer lifespans, while medium-sized breeds like English bulldogs and shih tzus have comparatively shorter life expectancies.
The study, utilizing data from 584,734 dogs across 155 breeds, reveals that large breeds and those with flat faces generally exhibit shorter average lifespans in contrast to their smaller and long-nosed counterparts. The research sourced data from diverse outlets, including veterinary records, pet insurance companies, and animal welfare charities.
On average, female dogs live slightly longer than their male counterparts. The overall mean lifespan across all dogs studied was 12.5 years, with small, long-nosed dogs demonstrating the highest life expectancy at 13.3 years. In contrast, medium-sized, flat-faced dogs had the lowest life expectancy, with males and females expected to live 9.1 and 9.6 years, respectively.
Certain breeds, like French bulldogs, St Bernards, and presa canarios, display notably shorter lifespans, according to Kirsten McMillan, Dogs Trust's data manager, a UK-based dog welfare charity, and one of the study's authors. While there are exceptions to these trends, the study emphasizes the need for further investigation into the multifaceted factors influencing varied lifespans among dog breeds.
These factors may include genetic predispositions, behavior, lifestyle, diet, and environmental influences. McMillan views this research as an opportunity to enhance the overall well-being of dogs, particularly for populations identified as being at risk of early mortality.
The study, grounded in a database of British dogs, acknowledges potential biases in these records and underscores the necessity for ongoing research to unravel the intricate factors shaping canine lifespans.

Experts Urge Dog Owners To Prioritize Health in Choosing Pet Companions
The popularity of flat-faced, or brachycephalic, dogs is often attributed to their adorable resemblance to human babies, according to past research. However, the distinct facial features that contribute to their cuteness also lead to significant respiratory challenges.
Dan O'Neill, who chairs the Brachycephalic Working Group, stresses the urgent "health and welfare crisis" confronting these breeds, urging potential owners to prioritize health over aesthetic preferences.
The rise of designer breeds, like labradoodles and cockapoos, signals a shift in the dog ownership landscape. Kirsten McMillan, Dogs Trust's data manager, notes this departure from traditional distinctions between mutts and purebred dogs.
While certain breeds may entail more frequent vet visits, McMillan underscores that the primary focus should be on the emotional commitment and care potential owners are willing to provide.
Highlighting the familial bond with pets, McMillan underscores that animals are family members. Prioritizing well-being over finances, the focus is on ensuring their prolonged, content, and healthy lives.
Prospective dog owners are advised to make informed decisions, considering health implications in the evolving landscape of designer breeds. The welfare of these beloved pets should be a paramount consideration in decision-making.
