A wiry-haired, 14-year-old Chihuahua mix is taking the Internet by storm this year. Her name is Susie, and she’s on a mission to connect homeless older dogs with the family that will love them.

Those who have had the pleasure of sharing their lives with a senior dog probably can‘t imagine allowing them to end up at a local humane society or animal control facility.

When Janetta Harvey adopted Susie-Belle — a Schnauzer who had spent her life as a breeder in a puppy mill, she knew that her new dog would finally get the life she deserved. What Janetta didn't realize was how much she would be inspired to change lives of other dogs like Susie-Belle.

As our dogs age, many of us may wish for a way to hold on to them forever. Since 2012, photographer Jane Sobel Klonsky has been doing that with her camera by capturing precious moments between people and their senior dogs.
