Herm Sprenger Ultra-Plus Prong Collar 3.0 mm x 18 in - Control

In this review of the Herm Sprenger Ultra-Plus Prong Dog Training Collar 3.0 mm x 18 in, the bottom line is simple: this is a precision-built correction tool aimed at owners of large breeds who need reliable, immediate feedback to curb pulling and reinforce training. The reviewer found the collar's patented center plate and symmetrical prong placement deliver consistent, natural contact, and the solid fastener plate makes fastening and securing the chain noticeably more reliable than cheaper alternatives. This collar is best used as part of supervised training under a handler who understands prong collar techniques.

Key Features

• Center plate construction: Patented center plate and symmetrical prongs provide even, natural contact so corrections feel consistent around the neck.
• Solid fastener plate: The solid fastener plate offers a more secure connection, reducing the chance of accidental opening during walks or training.
• Adjustable links: Individual links can be added or removed to fine tune fit and tension for gradual size adjustments.
• Chrome plated steel: Durable steel construction with chrome plating stands up to regular use and resists corrosion when rinsed and dried.
• Sizing guidance: The maker recommends adding 2 in to the dog's neck circumference and placing the collar higher on the neck for effective contact and control.

Who It's For

The Ultra-Plus 3.0 mm x 18 in collar is aimed at owners of medium to large breeds who need a dependable training aid to address pulling and reinforcement of leash manners; customers report strong results with German Shepherds, Rottweiler puppies and pitbull mixes. Trainers and experienced handlers who understand correct fitting and timing will get the best results and the most humane corrections.

Those who should look elsewhere include first-time owners uncomfortable with correction-style collars or those seeking a purely no-contact solution; also select a different size if your dog's neck circumference requires a longer chain length than the 18 in variation offers.

Pros & Cons

Pros

• High-quality build delivers consistent, natural contact that many customers called effective for stopping pulling.
• Solid fastener plate improves security, making the collar easier to close and less prone to accidental unfastening.
• Chrome plated steel construction increases durability and longevity compared with thin or plated base metals.

Cons

• Some users find handling and fitting the prong collar awkward at first, so there is a short learning curve to safe use.
• Requires proper placement high on the neck and supervised use; not suitable as a permanent everyday collar.
