Longevity Based on Breed, Size, and Gender
A recent study conducted by scientists in the UK delved into how a dog’s breed, size, sex, and face shape impact their lifespan. The findings showed that flat-faced dogs, large dogs, and male dogs typically have shorter life expectancies.
Longest Living Breeds:
Lancashire Heelers – 15.4 years
Tibetan Spaniels – 15.2 years
Shiba Inus – 14.6 years
Shortest Living Breeds:
Caucasian Shepherd – 5.4 years
Presa Canario – 7.7 years
Cane Corso – 8.1 years
Key Factors Influencing Lifespan
The study, published in the journal Scientific Reports, analyzed data from over half a million dogs to identify trends in longevity. It was discovered that body size, sex, and face shape play significant roles in a dog’s life expectancy.
Impacts of Size and Shape:
– Large dogs have a 20% higher risk of early death compared to small dogs.
– Dogs with flat faces are 40% more likely to experience early death due to breathing issues and heart disease.
Artificial Breeding Practices and Lifespan
The research also highlighted how artificial breeding practices have influenced dog lifespans. Inbreeding, trait selection, and population isolation have led to a reduction in genetic diversity, resulting in various health concerns among dogs.
This study aims to help prospective pet owners make informed decisions about choosing dog breeds and provide current dog owners with valuable insights to ensure their furry companions lead long, healthy lives.
