No electric shock!

Hunter's comment
The Chord Collar works with vibration and sound signals. At first I thought it would work with the conventional shock system but I continued researching and learned that it works without applying fear or discomfort to the animal.
The Chord Collar comes with many features, you can train behavior, play games and apply digital fences and leashes without any additional setup except for their app.
On top of it you can monitor your dog's health. Before you can use this digital collar you and your dog have to go through a personalized training program which is available on their app.
