This is an effective and harmless training method. The collar is controlled by a remote that sprays close to your dog’s nose whenever it engages in unwanted behaviour, without doing any harm. You can train your unleashed pet using the remote control, as it has a reach of 300 yards.
The collar can adjust to necks that measure up to 28″. The remote includes buttons for both positive and negative reinforcement and there are 4 levels of spray emission.
