These Bittersweet Portraits Show How Puppies Become Grown-Up Dogs

Amanda Jones recognizes the life-changing bond that often forms between people and their dogs. In her latest book, Dog Years: Faithful Friends, Then & Now, Jones set out to document the lives and stories of 30 dogs she photographed over her career. Inspired by her first dog, Lily, the book features black and white photos of each furry friend at both young and old ages, along with short bios written by the dogs’ human families for an inside look at their personalities.

“One thing that remains constant is the love people and dogs have for each other,” Jones wrote. “That does not change, no matter how many dog years go by.”
