Dog called a hero after calling 911 to help owner who was having a seizure

An assistance dog called a hero after calling 911 and saves his owner's life last week in Scottsdale, Arizona.

A dispatcher with the Scottsdale Police Department took a call from an assistance dog who barked on the other end of the line.

The dog is trained to call 911 whenever his owner lays down and is unresponsive. This isn't the first time the dog has called 911.

What a great dog!
