Fitting the NewTrix Dog Halter

The NewTrix™ dog halter stops pulling with calm, kind control. Pressure on the front of a dog’s neck or chest triggers an automatic reaction called the Opposition Reflex. This motor neuron response causes a dog to lean into the pressure, which actually encourages him to pull. It renders millions of dogs a tremendous challenge to manage on leash. The solution is simple.

Reverse it!

When your dog pulls, the NewTrix™ dog halter applies pressure behind his head which triggers the opposition reflex, but this time your dog leans back into it and stops pulling! The patented push-pulley mechanism applies pressure on the back of your dog’s neck and instantly puts this incredible force to work for you.
Stop pulling at its true source.

No pain, no fear. Pure science.

The NewTrix dog halter is comprised of 8 main parts: the fleece-lined Nose Strap, the Cheek and Chin Straps, the Side and Back Adjustment Slides, the Lateral Pivot Rings, the Nape Strap, and the Safety Lanyard. Grasp the halter by the fleece-lined Nose Strap, allowing the rest of the halter to dangle. Straighten the straps of the halter so they will sit flat against your dog’s face and neck.


Identify the two Lateral Pivot Rings which link the Cheek and Chin Straps to the Nape Strap. These rings will sit on the sides of your dog’s neck. The Nape Strap slips between these two rings to form the Push-Pulley mechanism. With one finger pull down on the Nape Strap between the Lateral Pivot Rings thus forming the Push-Pulley which will sit behind your dog’s head. You may need to move the Back Adjustment Slide each time to create an opening large enough for your dog’s head.


With a food treat, lure your dog to put his nose through the opening you’ve created.


Place the fleece-lined Nose Strap on your dog’s snout and while he’s busy with the treat slip the Nape Strap over his ears.


Make sure the Chin Straps do not get into his mouth, and that they crisscross under his chin. The ring under your dog’s chin is mainly for keeping these straps untangled.


Cinch down the Back Adjustment Slide on the Nape Strap so as to prevent the Nose Strap from slipping forward off the snout.


Connect the Safety Lanyard to your dog’s regular flat collar. Connect your leash to the ring on the end of the Nape Strap. Please read Teaching Your Dog NewTrix below. Enjoy your walk!


Cheek Strap Adjustments:

Check the fit on your dog’s face and remove the halter to make adjustments. Adjust the Cheek Straps equally on both sides, so they fit loosely and will pucker slightly. The Cheek Straps’ function is to prevent your dog from pawing the nose strap forward off his snout. (If the Cheek Straps are too short they will pull the Nose Strap toward your dog’s eyes.)


Chin Strap Adjustments:

Check the fit on your dog’s face and remove the halter to make adjustments. Your dog should be able to yawn fully. Pull the Chin Straps through the Adjustment Slides, shortening or lengthening the distance between the Adjustment Slide and the Lateral Pivot Ring. If your dog is on the lower end of the weight range for its size, there will be a greater amount of strap ‘in reserve’ between these points. This reserve can be fed into the Chin and Cheek Strap segments as your dog grows.

Quick Tests for the Right Fit

  1. Cheek Straps will be a little loose and pucker slightly. Fleece-lined Nose Strap will not ride up into dog’s eyes. To make corrections see:
    Cheek Strap Adjustments above.
  2. Your dog will be able to open his mouth wide. To make a correction see: Chin Strap Adjustments above.
  3. With a correctly adjusted Nape Strap you will not be able to pull the Nose Strap forward off the dog’s snout. Long-nosed dogs may tolerate
    a looser adjustment. See Instruction 6 above
  4. Cheek and Chin Straps will be equal on both sides.

Teaching your dog NewTrix

  • When introducing the NewTrix™ dog halter take the time to create positive associations. With a food treat, lure your dog to put his nose through the halter; position the straps while he’s busy eating.
  • Distract your dog from pawing at the NewTrix™ dog halter and reward him with food, praise and attention when he leaves it alone.
  • Practice a loose leash walk in an enclosed area where your dog has no strong motivation to go elsewhere.
  • Resist your dog’s pull with a brief pulse of tension to halt his forward motion. If he continues to pull, the halter will apply gentle pressure symmetrically around his head and snout to restrain him. Releasing the tension is a powerful reinforcement for him to stop pulling.
  • Move forward only when the leash is loose.
