Talk about man's best friend.
A German Shepherd in Scottsdale, Arizona, dialed 911 after his owner, Joe Stalnaker, collapsed while having a seizure. This isn't the first time the dog has called 911 -- police say the dog has previously dialed the emergency line twice when Stalnaker suffered a seizure.
Buddy, an 18-month old puppy, is specially trained to hit programmed buttons on the telephone when Stalnaker seizes, a result of a head injury suffered 10 years ago during a military training exercise.
Buddy then whimpers and barks into the phone until help arrives.
