Herm Sprenger 2.25mm Stainless Steel Ultra Plus - Twin O Ring Prong Collar - Black

£36.00

2.25mm Ultra-Plus Twin O Ring Prong Collar is the brand's most popular gauge — built for everyday training across small to medium breeds where precise, even-pressure feedback matters.

Made in Germany from precision-cast components, the 2.25mm wire pairs with the centre-plate configuration first pioneered on Herm Sprenger's Neck Tech range. The twin O ring setup gives you flexibility on the lead — clip a single ring for standard correction, or both rings together for more direct, two-point feedback in higher-distraction work.

Best suited to dogs between 7 and 18kg — Cocker Spaniels, French Bulldogs, Boston Terriers, Beagles, Cavalier King Charles Spaniels, Brittanys, Jack Russells, Border Terriers, Standard Schnauzers (smaller frame), and similarly-sized breeds.

Common use cases

  • Heel work and obedience for medium-to-large dogs
  • Reactive and redirected-aggression handling
  • Sport, protection, and working-line training
  • Stronger pullers where lighter gauges flex too much under load

Please note: As with any training tool, you must condition the dog to the tool to ensure the best results. Training tools and equipment do not magically fix issues, but when introduced and conditioned properly, can improve and build strong communication between you and your dog.

We do not condone the improper use of our training prong collars. We strongly recommend seeking professional advice before utilising any training tool. To browse our list of dog trainers and behaviourists, please click here.

Features & Benefits
  • Even Pressure Distribution
    The Ultra Plus centre plate design distributes pressure evenly around the neck rather than concentrating force on the trachea like traditional flat collars.  

  • Machine-Rounded Prongs
    Each link is precision-finished with smooth rounded edges to maximise comfort and reduce the risk of fur or skin irritation.

 

  • High Quality German Engineering
    Manufactured by Herm Sprenger using premium stainless steel for long-term durability, reliability, and consistent performance.

  • Adjustable Fit
    Easily customised by adding or removing individual links to achieve a secure, high-positioned fit behind the ears for optimal communication.  

  • Instant Pressure Release
    Designed to provide clear on/off feedback to the dog, helping improve timing and communication during training.  

  • Symmetrical Ultra Plus Design
    Balanced centre plate configuration helps maintain a more consistent collar position during use while offering a cleaner, professional appearance.  

  • Suitable For Working & Active Dogs
    Commonly used within obedience, working dog handling, protection sports, and structured loose lead training when introduced correctly by an experienced handler.

  • Professional Training Tool
    Designed for use alongside structured training and guidance from an experienced trainer. Not intended as a substitute for training or everyday unsupervised wear
More Info

How the Twin O-Ring works.

  • The Twin O-Ring configuration gives you two attachment points on the collar — one on each side. Standard use is to clip your lead to a single ring for everyday correction, but you can attach both rings simultaneously for more direct, two-point feedback in higher-distraction work or when introducing the collar to a new dog. Many trainers use the dual-ring setup during initial conditioning when the dog needs the clearest possible feedback, then transition to single-ring for everyday handling once the conditioning is established.

Benefits include:

  • Reduced leash twisting during movement
  • Smoother lead handling and transitions
  • Improved positioning during obedience work
  • Enhanced durability compared to traditional chain attachment points
  • Cleaner and more stable leash connection

Precision German Engineering

  • Herm Sprenger collars are trusted worldwide within professional dog training, working dog handling, and canine sports due to their exceptional manufacturing quality.

Each prong is:

  • Machine-rounded for improved comfort
  • Precision engineered for consistent pressure distribution
  • Manufactured using high-quality stainless steel
  • Designed for long-term durability and corrosion resistance


The collar is adjustable by adding or removing links to achieve the correct fit for your dog.

Suitable For

  • Loose lead walking training
  • Obedience training
  • Working dogs
  • Protection sports
  • IGP / PSA / KNPV style training
  • Strong or high-drive dogs requiring clearer communication

Important Fit & Usage Guidance

For correct use, the collar should sit high on the dog’s neck directly behind the ears and fit snugly without excessive movement.

This product is intended for use within structured training and should be introduced correctly by an experienced handler or trainer. The collar should never be left on an unattended dog.
