SportDOG Contain + Train Add-A-Dog Containment Collar

Train and contain more dogs with ease.
The SportDOG® Contain + Train™ Add-A-Dog® Collar (SDF-CTR) lets you add an additional dog to your SportDOG® Contain + Train™ system (Model SDF-CT-22) or replace an existing collar receiver. Whether you’re managing a multi-dog household or expanding your training program, this collar offers seamless integration and top-tier performance for both training and containment needs.

This dual-function collar supports both Containment Mode and Training Mode, offering 7 levels of static stimulation, along with tone and vibration options. In Training Mode, stimulation can be adjusted across low, medium, and high ranges, helping you tailor correction to your dog's temperament and training goals.

Engineered for durability, the collar features SportDOG®’s waterproof DryTek® technology, making it fully submersible up to 3 metres — ideal for active, outdoor dogs in any environment. Suitable for dogs weighing 4.5 kg or more, the collar is paired with a vibrant 2.5 cm orange strap for high visibility and a secure fit.
