How do you use a step in harness?

To use a step-in harness, first lay it flat on the ground with the D-ring facing up. Have your dog step into the harness with their front legs, then pull the harness up and buckle it around their back, ensuring it's snug but not too tight. Adjust the straps as needed for a secure fit, making sure you can still slip two fingers underneath. Finally, attach the leash to the D-ring and you're ready to go!
