This collar is designed for leash walks and obedience training with large, strong dogs. Its prong action applies contact around the neck to support handler-to-dog communication, while the adjustable links let you tailor the collar’s length. Choose a fit by measuring your dog’s neck and comparing it with the stated size guidance.

What is the Herm Sprenger Ultra-Plus collar designed for?

It is intended for walking and obedience training with large, strong dogs. The prongs gently pinch the neck, a sensation the design compares to a mother dog’s corrective pinch of her puppies. The center plate and symmetrical arrangement are designed to provide natural contact for communication during training.

• Training purpose: leash walking and obedience work.
• Contact mechanism: prongs apply a gentle pinch around the neck.
• Design: Ultra-Plus construction with a patented center plate.

How do I choose the collar size?

The 16-inch collar is specified for necks up to 13 inches. Measure your dog’s neck before choosing a fit; the sizing guidance gives an allowance of 3–4 inches beyond the neck circumference. Individual links can be added or removed to adjust the collar.

• Link size: 2.25 mm.
• Overall collar length: 16 inches (40.64 cm).
• Stated maximum neck size: 13 inches (33.02 cm).

Good to know: the sizing instructions give both a 3-inch and a 4-inch allowance, so use the stated fit limit of up to 13 inches as a practical reference.

What features support leash attachment and fit adjustment?

A swivel provides the leash attachment point, and the collar’s individual links can be added or removed for adjustment. Its black stainless steel links are arranged symmetrically around a patented center plate.

• Leash connection: swivel attachment.
• Fit adjustment: removable or addable individual links.
• Made in Germany by Herm Sprenger.

This Herm Sprenger collar is suited to handlers training large, strong dogs for walks or obedience and who need an adjustable prong design with a swivel leash connection. Its 16-inch overall length is specified for necks up to 13 inches.
