Fitting the Harness on your Dog

It is important to ensure that the chest strap and lower strap are adjusted correctly. Improper fitting may cause discomfort or injury.

If the harness straps are too tight, the buckle rubs against the dog's skin around the armpit area, which may lead to chafing. If the harness straps are too loose, there may be enough room for your dog to shuffle out of the harness.

Correct Fitting

When the lower chest strap is adjusted correctly, you should be able fit your fingers between the harness and your dogs back. A properly fitted harness will keep you in control, ensuring no unnecessary pressure is applied to other parts of your dog's body


Please Note - some differences exist between the range:

  • Rubber strap closure handle to hold down the handle (Not available on Mini / Mini-mini)
  • Velcro pad to secure the handle (Not on Size 0-3)
  • Large sidebag fixing option (Not available on Mini-mini - Velcro only)
