Remote Fetch: Ball chasing is very good exercise for pooches, even if it can cause obsession and anti social tendencies that will result in thousands of dollars in dog therapy. Capable of being remote triggered at 7 or 15 second intervals, or just automatically throwing balls your dog drops in the bucket, it might be worth the trouble. Think of it as the equivalent of a video game for a dog. And it's better than a doggie treadmill, which you can't really leave a dog unsupervised on for very long. $120 [Remote Fetch]
