By now, most people are aware that smaller dogs generally live longer than their larger counterparts, but by how much exactly?
A 2013 report by Banfield Pet Hospital revealed that most dogs that weighed less than 19 pounds had an average lifespan of approximately 11.3 years, while medium to large dogs in the 20- to 90-pounds range lived approximately 10.8 years, and even larger dogs more than 90 pounds usually only lived until the eight-year mark.
There are several differentiating factors when you compare a Chihuahua lifespan to, say, a pitbull lifespan, but even amongst small dogs, there’s a wide range of life expectancies. So, if you’re looking for a furry companion that will be around for a long time, make sure to narrow your search to one of the following longest living dog breeds.
