When you bring a dog into your life, you hope to enjoy as many years together as possible. While no one can predict exactly how long a dog will live, some breeds are known for their impressive lifespans. In this blog, we’ll look at the longest living dog breeds, why smaller dogs tend to live longer, and how you can support a long, healthy life for your pup.
