“No Dog Should Die Alone" was the attention-grabbing — and heart-stirring — headline of journalist Laura T. Coffey’s TODAY show website story about photographer Lori Fusaro’s work with senior shelter pets. While generally calm, easy, and already house-trained, these animals often represent the highest-risk population at shelters.

With gorgeous, joyful photographs and sweet, funny, true tales of “old dogs learning new tricks,” Coffey and Fusaro show that adopting a senior can be even more rewarding than choosing a younger dog. You’ll meet endearing elders like Marnie, the irresistible shih tzu who has posed for selfies with Tina Fey, James Franco, and Betty White; Remy, a soulful nine-year-old dog adopted by elderly nuns; George Clooney’s cocker spaniel, Einstein; Susie, the funny little senior dog who got adopted by "Humans of New York" creator Brandon Stanton and "Susie's Senior Dogs" founder Erin Stanton; and Bretagne, the last known surviving search dog from Ground Zero.

They may be slower moving and a tad less exuberant than puppies, but these pooches prove that adopting a senior brings immeasurable joy, earnest devotion, and unconditional love.
