Photographer Lori Fusaro is compiling photos of older animals for a book she hopes will inspire people to think about adopting older pets from shelters. Fusaro's idea for the book coalesced when she met Sunny, an ailing 16-year-old mixed-breed dog, at a Los Angeles shelter. Fusaro adopted her, and a year later, they are still together. Fusaro knows letting go will be difficult. "I didn't want to open my heart for that kind of pain, but how much sadder and more horrible for me would it be to leave her at the shelter," said Fusaro. "It will be terrible to lose her but much worse to leave her to die alone."
