Tips & Tricks of learning how to get your dog inside the sports sack. 

Walk-In Method

• Have your dog stand or walk onto the bag.

  Place front paws through the arm holes. 

  Clip the top collar enclosure buckle.

  Place back legs in and zip up.

  Feed collar enclosure buckle through zipper loop.

  Tighten side cinches, collar enclosure, and back lumbar straps.

  Safety, Sizing & Comfort Features:

  Be sure you are using the features found on the K9 Sport Sack as they help you and your dog have the best experience using the carrier. 

• Carabiner Collar Clip: Prevents your dog from getting out of the bag

  Side Cinch Straps: This helps keep your dog in a forward position and not lean backwards. Be sure to tighten these down as much as they can.

  Collar Enclosure: This will ensure that your dog doesn't force itself up and out of the bag and helps prevent leaning as well. Be sure to tighten this enough. 

  Lumbar Back Straps: This supports the Zipper and helps size the bag.

  Zipper Loop: Thread collar enclosure buckle through the zipper loop found on each of our models (except for the Urban model) to ensure that the zipper stays fastened.

  All of our carriers come equipped with non-slip zippers, but this is an additional feature we recommend using.
