Considering that the pet-breeding industry contributes to animal overpopulation, it makes sense to adopt a dog. Leela, 10, spent most of her life in a cage at a puppy mill as a breeding female  until Wonder Dog Rescue found her a home. Photo by Lori Eanes. 

Monty, 7, was adopted as a puppy from Michigan's Humane Society and now lives in San Francisco. The Humane Society estimates that animal shelters admit 6 to 8 million cats and dogs each year. Photo by Lori Eanes.

Lex (left), 10, was saved by Rocket Dog Rescue just one day before being euthanized at a shelter; he lives with Leela (right). Their owners use biodegradable corn-based bags to clean up after them. Photos by Lori Eanes.

Stella, 1, was adopted from the San Francisco SPCA just a few weeks before these photos were taken. Photos by Lori Eanes.

Instead of driving the nearly two miles to our photo shoot, Monty's owner chose to walk. Photo by Lori Eanes.

Lex's favorite food is organic turkey, sweet potato and peas from By Nature. Photo by Lori Eanes.
