Herm Sprenger Prong Dog Training Collar, Black 16-Inch with Quick-Release Buckle

Herm Sprenger’s black prong dog training collar is designed to aid behavior correction when a dog pulls, with a 16 in (40.64 cm) collar and 2.25 mm pronged links.

• Fits necks up to 13–14 in (33.02–35.56 cm) — choose by measuring your dog’s neck.
• Chrome-plated steel links — the assembly chain tightens when the dog pulls.
• ClickLock quick-release buckle — put the collar on and take it off without pulling it over the dog’s head.
• Swivel D ring — lets the leash rotate 360 degrees to help prevent tangling.
• US-made Biothane insert — adds stability and security to the buckle.

This collar is for training walks where pulling is the behavior being addressed. Its adjustable link design lets you tailor the fit, while the buckle and rotating leash ring make it easier to put on and connect a leash. Measure for fit before choosing this size.

How do I choose the right fit?

Measure your dog’s neck and use the stated neck range as your sizing guide. The collar should sit snugly under the ears and along the jawline for training use. Add or remove pronged links to adjust the fit as needed.

• Collar size: 16 in (40.64 cm).
• Link thickness: 2.25 mm.
• Intended neck range: up to 13–14 in (33.02–35.56 cm).

How does the buckle and leash attachment work?

The ClickLock buckle provides quick placement and removal, so the collar does not need to pass over the dog’s head. The swivel D ring rotates through 360 degrees, allowing leash movement without the ring staying fixed in one direction.

• The Biothane insert increases buckle stability and security.
• Biothane inserts are available in different colors for a personalized look.
• This version is black.

What is the collar designed to do during training?

The assembly chain tightens when the dog pulls, providing the collar’s behavior-correction action. Herm Sprenger makes the collar in Germany, and it is assembled and enhanced with a US-made Biothane insert in the USA.

• Material: chrome-plated steel prong links.
• Adjustable construction: links can be added or removed for fit.
• Use the snug position under the ears and jawline for training.

This collar is suited to handlers looking for an adjustable prong training collar with a quick-release buckle and a rotating leash attachment. It is sized for dogs whose neck measurement falls within the stated range, and its chain tightens when the dog pulls.
