Determine if the study involves observational or experimental.
A dog food company wants to compare a new lower-calorie food with their standard dog food
to see if it's effective in helping inactive dogs maintain a healthy weight. They have found
several dog owners willing to participate in the trial. The dogs have been classified as small,
medium, or large breeds, and the company will supply some owners of each size of dog with
one of the two foods. The owners have agreed not to feed their dogs anything else for a
period of 6 months, after which the dogs' weights will be checked.
