These two dogs are fascinated by their own shadow

This brother and sister German Shepherd pair don't need the finer things in life to keep them happy – their shadows will do just that.

The video, filmed in Saratoga Springs, New York, shows the dogs chasing their own shadows and barking excitedly.

"They came into my dealership with their owner for service on a vehicle and this is how they entertained themselves while waiting," the filmer said.
