Will my dog feel comfortable or stressed inside the backpack?
Will my dog feel comfortable or stressed inside the backpack?
Most dogs need a little time to get used to a carrier. We recommend introducing the backpack at home first, using treats and short practice sessions before longer walks.
Place your dog inside in a seated position, attach the internal safety clip, and adjust the straps so the carrier sits close and stable against your back.
Your dog’s front paws can stay inside the bag or rest gently over the front/top edge — choose the position where your dog feels most relaxed.
