SportDOG Brand SportHunter 6-Dog Expandable Remote Trainers
Featuring an Add-a-Dog collar feature, the SportDOG Brand 6 dog remote trainers are among the best choices for your dog. With the purchase of additional collars, you can train up to 6 dogs with just one of the remotes. This feature is great, more so if you are a professional dog trainer.
As you train the dogs, you can alternate between a beeping tone and a vibration (buzz). It eliminates the need for the current shocks used in remote collars.
