A proper collar is an effective training tool for working dogs. At Working Pets Plus, you can find a large selection of training collars for a variety of training methods and applications. We have agitation collars with built-in handles for off-leash protection training, agitation work, and search and rescue. They are handmade by the Amish with the finest quality leather for reliable durability and performance and feature heavy-duty buckles to withstand constant pulling. Our Herm Sprenger collars are one of the most used training collars by professionals and everyday pet owners. They are resistant to corrosion, easy to clean, and will distribute correction pressure evenly around your dog's neck. You can add or remove links for a more secure fit around your dog's neck.
