Dogs Catching Frisbees

Some dogs are highly adept not only at retrieving but also at catching in midair a tossed ball or Frisbee. To do so requires the dog to be in the right place at the right time. How does a dog navigate to snatch a Frisbee out of the air?

To find out, researchers attached a tiny video camera to the head of each of two dogs to capture what the dogs could see as they hunted, then intercepted Frisbees.
