Inspired by The Invictus Game that uses the power of sports to inspire recovery, rehabilitation and support for wounded, injured and sick servicemen and women, this support harness was designed with the same aim of encouragement and supportive spirit for our 4-legged companions. Built from 1000D nylon of rugged durability, it’s reinforced with quality metal accessories and UTX-Duraflex® quick-release buckles. The 360º support design offers multiple adjustment points, rear leg support straps, vertical and horizontal handles, and a front chest piece that doesn’t interfere with front leg movement. Available in multiple sizes, the INVICTUS Support Harness is mesh lined for breathability for daily use in all seasons, and the rear leg support straps can be removed/configured for more flexibility.

A well-fitted harness or collar should allow enough room for you to fit your two fingers between the dog's body and the harness/collar. The dog harness should be 4 cm shorter than their back length.

Once you have the measurements, you can compare them with the size chart provided by the harness manufacturer. Always round up to the nearest size if your dog's measurements fall between two sizes, and adjust the harness according to the instructions provided to ensure a secure fit.

Remember, a correctly fitted harness should be snug but not too tight, and you should be able to fit two fingers between the harness and your dog's body at any point.

Caring for pet gear like harnesses, collars, leashes, and accessories made from durable materials such as nylon, Cordura, and Multicam fabric involves a few general guidelines to ensure they last longer and remain safe for your pet. Here's a basic care instruction outline for these items:

For Nylon Products (Harnesses, Collars, Leashes):


  • Hand wash with mild detergent in warm water to remove dirt and odors.
  • Use a soft brush to scrub away tough stains.
  • Avoid bleach or other harsh chemicals that can degrade the material.
  • Rinse thoroughly to remove all soap residues.


  • Air dry by hanging or laying out flat away from direct sunlight, as UV rays can weaken the fibers over time.
  • Do not use a high-heat setting on a dryer, as this can melt or warp the material.

General Care:

  • Inspect regularly for signs of wear and tear, especially around the buckles and adjustment points.
  • Avoid excessive pulling or strain on buckles and attachment points.
  • Store in a dry, cool place when not in use to prevent mildew or material degradation.

For Cordura and Multicam Fabric Items:

Cordura and Multicam fabrics are known for their durability and resistance to abrasions, tears, and scuffs.


  • Gently brush off any loose dirt or debris.
  • Clean with a sponge or soft cloth dampened with water and, if necessary, a mild soap.
  • For stubborn stains, use a soft-bristled brush to gently scrub.
  • Avoid soaking these materials as it may affect the integrity of the fabric coatings.


  • Air dry by laying the item flat or hanging it up.
  • Do not expose to direct heat or sunlight for extended periods.

General Care:

  • Regularly inspect for damage to ensure the safety and comfort of your pet.
  • Look for loose threads or abrasions that may need to be repaired.
  • Avoid storing in damp or humid conditions to prevent mold or mildew.

For All Items:

Hardware Care:

  • Wipe down any metal parts to prevent rust or corrosion.
  • Ensure that buckles and clips function properly and are not damaged.
  • Lubricate any moving parts if necessary to keep them working smoothly.

Safety Checks:

  • Before each use, check for any signs of wear or damage.
  • Replace the item if any part of it seems unreliable or unsafe for your pet.


  • Dragging the gear on rough surfaces which can cause premature wear.
  • Letting your pet chew on the gear, as this can cause damage that may lead to failure.


  • If the material is torn or the stitching comes undone, consider having it professionally repaired to maintain its strength and functionality.

By following these care instructions, your pet's harnesses, collars, leashes, and accessories should remain in good condition, ensuring they are safe and comfortable for your pet to use.
