Herm Sprenger Dog Training Prong Collar, 23 in, 3.2 mm Steel with Quick Release

Herm Sprenger’s chrome-plated steel prong collar is designed for dog obedience training and controlled walks, with a 23 in (58 cm) overall length and a 3.2 mm wire gauge for dogs with necks up to 19 in (48.3 cm).

• Fits neck circumferences up to 19 in (48.3 cm) — provides a clear sizing limit for choosing the right fit.
• 3.2 mm chrome-plated steel links — create a leash-operated training collar with a corrosion-resistant finish.
• Smooth, rounded link edges — provide a shaped contact surface around the dog’s neck.
• Quick-release snap — makes the collar easier to put on and remove.
• Made in Germany by Herm Sprenger — offers a specific country of manufacture.

This collar is made for training walks and basic obedience work where a handler wants a correction tool for managing pulling or other unwanted walking behavior. Its prong-link design responds to leash tension and is intended to interrupt behavior promptly. It is a training aid, not a substitute for appropriate handling and supervision.

What is the Herm Sprenger prong collar designed to do?

It is designed to support behavior correction and teach more responsive walking habits during dog training. When leash tension is applied, the links provide a correction intended to interrupt unwanted behavior; the collar is also recommended for professional obedience training. Its design avoids applying direct pressure to the trachea, and the center plate helps distribute pressure across the collar.

• Suitable for basic obedience training and controlled walks.
• The center plate lets the middle link sit symmetrically, so the prongs tighten in the same direction.
• Pairing a backup collar with the prong collar on the leash is supported.

How do I choose the right size and adjust the fit?

This 23 in (58 cm) collar is intended for dogs with a neck circumference of up to 19 in (48.3 cm), and it should sit snugly high on the neck, just behind the ears. Measure your dog’s neck circumference before choosing it, and compare that measurement with the 19 in maximum. Fit can be adjusted by adding or removing individual links, which changes the collar’s length.

• The overall collar length is 23 in (58 cm); the maximum neck circumference is 19 in (48.3 cm).
• Its 3.2 mm wire gauge identifies the thickness of the steel links.
• Adjust the fit by changing the number of links rather than relying on a sliding buckle.

What are the collar’s construction and fastening features?

The collar is made from chrome-plated steel, with smooth, rounded links and a center plate connector. The chrome surface gives the collar its bright silver appearance, helps resist corrosion, and is easy to clean. Herm Sprenger describes the collar as handmade and designed for durable use.

• A quick-release snap allows convenient fastening and removal.
• The center plate supports symmetrical link positioning and even pressure distribution.
• The smooth chrome finish is intended to make routine cleaning easier.

This Herm Sprenger collar suits handlers working on obedience and leash responsiveness with a dog whose neck measures no more than 19 in (48.3 cm). Its adjustable links, quick-release snap, and chrome-plated steel construction make it a purpose-built training collar for that fit range, rather than a collar for dogs with larger necks.
