The SportDOG Brand YardTrainer 100S is a compact, waterproof training collar system built for stubborn, high-drive dogs who need reliable remote communication during yard work and park sessions. If you're training a dog with a strong will or short attention span within a 100-yard radius, this system delivers the stimulation variety and durability needed to keep training sessions consistent and effective. The YardTrainer 100S offers three distinct stimulation types—tone, vibration, and eight levels of static stimulation—each accessible via dedicated buttons on the remote, so you can match the correction to your dog's temperament and the training situation without fumbling.

Built with DryTek waterproof technology, the YardTrainer 100S stands up to wet conditions and is fully submersible to 25 feet, making it practical for real-world training in any weather or environment. Both the receiver collar and remote transmitter are rechargeable; the receiver runs 50–70 hours per charge, while the remote lasts 20–25 hours—both charge in about 2 hours. A low-battery indicator keeps you aware before power runs out mid-session, and the intuitive three-button layout means you can operate it by feel, keeping your focus on your dog rather than your equipment.

The system comes ready to train out of the box: receiver collar with 3/4" strap, two sets of contact points (standard and long), remote transmitter with lanyard, charge cable, test light, and training guides. The receiver fits dogs 8 pounds and up with neck sizes from 5" to 22", and the compact form factor—receiver is just 2.6" long—won't bulk up your dog's collar. This is a single-dog system, not expandable, so it's sized for straightforward one-on-one yard and park training.
