How to get your dog in the backpack

All K9 Sport Sack carriers are specially developed under the close direction of animal professionals, veterinarians, dog trainers, and outdoor product engineers to be ergonomic, safe, and strong.

  • Your dog may stand in the bag for the first 5-10 minutes (allow your dog time to settle into the bag before you decide its the wrong size).
  • The K9 Sport Sack does require a little bit of training. If your dog doesn’t get in the first time, don't worry! Be patient, loving, and offer high praise when trying on the bag. Always make the experience a positive one.
  • We have found the Walk-In method to be a great way of getting your dog in the bag. View it at: https://www.youtube.com/watch?v=iqCLIcxzsHE

        Size Guide

        L: 20-23in (51-58cm)

        XL: 23-26in (58-66cm)

        XXL: 26-29in (66-74cm)


        How to decide on the right size for your dog

        What if you have a puppy that is still growing? Try to get an idea for how big your dog will become weight wise, length wise from collar to base of tail, and chest girth wise based off of breed or parents. Then, purchase that sized carrier along with a booster block. If we're out of booster blocks, you can use pillows, towels, yoga blocks, or other similar items. Some customers go to craft stores, purchase a 3 inch foam block, and cut it to fit the carrier.
