Levels dog training shows a variety of behaviors with steps to complete each behavior. You can test your dog on each step and the app will calculate their percentage and mark the behavior as checkmarked or done when the behavior reaches 90%. For more information on the levels program, visit http://www.dragonflyllama.com/%20dogs/%20dog1/levels.html ** There is a small bug with the app crashing upon selecting a dog. This will be fixed in the next update.
