Canine Scientist

There's an 8 year old dog named Tucker who was a stray in Seattle but is now a canine scientist who detects and tracks the scent of killer whale scat (poo) off the coast of San Juan Island, Washington, USA. 

The scientists use the scat to see where the whales have been and to monitor their health.

Tuckers payment is playtime with his favourite orange ball on a rope.

I think it's really cool that a dog can do that!
