Just in case anyone's confused about Ken Foster's canine love, he sports a T-shirt that reads, "I Love My Pit Bull," and shares his camera time with his own pet pit bull, Sula.

Sula's mutual affection for her owner is evident, as she eagerly licks his face. That symbiosis is one of the major tenets of Foster's most recent book, The Dogs Who Found Me. The non-fiction work is about 17 stray dogs that Foster has rescued throughout his life and, as he puts it, "how they helped me."

Foster's dogs comforted him through 9/11, Hurricane Katrina, and other traumatic events. In this 2-minute video, he explains how his dogs helped him realize he had a near-fatal heart condition.
