Your dog is strong. They know it. Your harness should be stronger.

Most harnesses are tested for average dogs. A 40kg Labrador lunging at a squirrel is not an average load - and a clip that fails at the wrong moment is not something you get a second chance at.

The Trail and Glow is strength tested to 250kg. Every D-ring, every buckle, every stitch. Built for the dogs that actually need it.

Back-clip harnesses give big dogs maximum leverage to pull - the same principle used to harness sled dogs. At 30, 40, 50kg, that is not a nuisance. It is dangerous. The Trail and Glow clips to the front of the chest. Your dog's own  forward force pivots them back toward you. The bigger they are, the better it works.

When a large dog hits the end of a collar and lead, the force on their trachea is considerable. The British  Veterinary Association advises against collar and lead walking for any dog that pulls - and for big dogs, the forces involved make that advice urgent. The Trail and Glow spreads all of that force across the wide chest panel. No pressure on the  throat - regardless of how hard they pull.

A Labrador lunging toward traffic. A Rottweiler fixating on another dog. A Shepherd deciding they have spotted something across the road. At that size and speed, a lead in your hand is not fast enough. The padded grab handle on the Trail and Glow gives you one-hand close control in half a second. The bigger the dog, the more you will need it.

Most harnesses max out at a size that fits a medium Spaniel. The Trail and Glow runs from XXS to XL - and the XL is built for the breeds that need it. Labradors, German Shepherds, Staffies, Rottweilers, Mastiffs. Same British design.  Same strength-tested hardware. Sized for the dogs that actually put harnesses to the test.
