Dog-approved toy!
This dog toy was initially confusing because the instructions did not say or show where to find the power button and charging port. They were nowhere to be found until I realized I could unscrew the bottom part of the ball from the top (see picture). That revealed the button and port -- problem solved. Then on to the dog test. Our dog was initially confused by and ultimately fascinated with the ball as seen in the video. There are several operating modes depending on how active your dog is/wants to be. The toy seems quite rugged, so immune to rough dogplay, at least from a golden retriever. Our dog considers this a hit!
