This short film about two best friends saying goodbye is truly heartbreaking.

Photographer Ben Moon first met his best friend Denali 14 years ago, when he picked him up from a dog pound. Since then, through thousands of adventures and Ben's long but successful battle with Cancer, the pair were inseparable.

Narrated from Denali's perspective, the film takes a look back through the pairs adventures around the US together, and looks at the dogs last few days as a Cancer of his own became fatal.

The touching film has now gone viral, and has won a couple of awards at the prestigious 5Point Film Festival in Colorado.
