Tips
Encourage your dog with praise and treats.
Find a stress-free environment, such as a quiet, indoor space.
Dogs may tense up during the fitting process, so check the fit after your dog has worn the harness for a few minutes.

Fit the shoulder straps around your dog’s shoulders so the seat belt handle lies between your dog’s shoulder blades.
Important: The seat belt handle is designed to prevent your dog from interfering with your driving. This is not a crash-tested safety restraint.

Adjust the shoulder straps so that the chest O-Ring is on or above your dog’s breast bone.
Important: Correct placement of the O-Ring is needed for your dog's comfort and the no-pull function.

Bring the girth straps between the dog’s front legs.

Attach the girth straps to the buckles on your dog’s back and adjust for a snug fit.

Adjust the grey strap under your dog’s chest for a snug fit. Make sure the strap is not hanging off your dog’s chest.

When fit properly, two fingers should barely fit between the skin and nylon strap. This prevents the harness from moving and chafing your dog’s skin.
Important: If your harness is the wrong size for your dog, check out our Perfect Fit Guarantee to ensure that your dog gets the right size.
