Here's the dog activity tracker which could actually help your dog stop barking!
Delta Smart is a new range which starts with a unit that's attached to your dog's collar. It will take note of what they get up when you're not there and show how energetic they've been throughout the day.
On top of that you can use the included app to train your dog. This means things like the device making a tone or vibration whenever it hears your dog barking. You can also get special tags to place around the house that will detect your pooch and can stop them from going into areas where they shouldn't.
