Heart of a Dog [Criterion Collection] [Blu-ray] 
As a longtime fan of Laurie Anderson I am more than familiar with her esoteric and engaging worldview. That's the first thing you need to know if coming to this feature from a canine love angle. Laurie does not think like the rest of us do. She can be playful, vague, unusual, and even infuriating in the way that she thinks. You need to know this because if you're approaching this film through a simple love of dogs, then you may be surprised or even incredulous.
If comfortable or familiar with Laurie's engaging and abstract style, this movie will take you to places that you won't expect to go. It's beautifully shot, wickedly funny, and heart-breaking. Laurie and her husband Lou Reed's love of their pet dog is apparent, and despite the film's relatively short running time, it has a wide reach and emotional heft that will stay with you long after it's done.
I thoroughly recommend it.
