When is my dog ready for level 4?

Move to level 4 when your dog is doing a pretty good job of ignoring the “alley cat” sound. When you first start level 4, adjust the time interval back to 10 seconds and increase the time interval by 5 seconds every 5-10 game sessions. When your dog is playing at a time interval of 30 second or more, try making the time interval random. Once your dog earns the level 3 achievement badge, consider moving to level 4.
