Chienne de vie -- Film Description:
"Their names are Tamara, Popeye, Charlie, Rosie, Idéfix... They're more than just best friends, they're inseparable companions who share the best, and especially the worst, of what their homeless owners experience every day. Their companionship and loyalty helps them keep their spirits up and stay grounded in their solitary, marginal, unsettled lives. Filming in Montreal and Toronto, Hélène Choquette [...] spent four seasons gathering seven homeless persons' frank thoughts on the benefits and drawbacks of having a dog while living on the street. An intimate portrait of a unique, affectionate and powerful relationship in which humans and animals care for each other."
