Amanda Jones has dedicated the past 20 years to an incredible photographic project that aims to show how ephemeral the lives of our beloved pets are. We all had the strange feeling that a lively puppy seems to turn into a wise, adult old dog during the night. Some of them are almost unable to change, others are beginning to show signs of aging. Dogs in particular age faster than we do, of course, and that may be why the following pictures are a little sad and very sweet. But we can always console ourselves knowing that, no matter how old they are, the joy we derive from this bond with our best friend never diminishes.
