The picture was taken in my backyard where I go to play with my dog, Nixon, who is also my best friend. A synonym for investigation is exploration. Even though my backyard is not huge, it still is big enough that my dog wants to explore it. Dogs can hear, smell, and see things that humans cant. That's what makes them better when it comes to investigation or exploration. Have you ever heard of the phrase, " curiosity killed the cat?" Well, it's good thing he is not a cat.
