 Customer Reviews

Is it comfortable for my dog?

  • Yes, very comfortable!  Your dog sits in the "begging position" which is a natural position that creates no hard pressure points.  The K9 Sport Sack is created with sturdy, supportive fabric as well as strategically placed support straps that, when fastened correctly, distribute weight evenly throughout and keep the passenger in an upright position.  The stiff rest pad on the bag's floor supports the dog's weight without bending or twisting, your back acts as a stabilizer and the lumbar support straps straighten the back so he/she sits up tall and straight to see over your shoulder for an exciting adventure they can be involved in.  Just remember to give your dog breaks.  We recommend a break of 15 minutes for every 45 minute ride. 

Is there a weight limit?

  • Yes!  We carefully identified the AIR PLUS' 40 LB weight limit with your dog's safety in mind and through extensive testing/quality control.  Any dog over 40 LBS voids the warranty and is ineligible for a return/refund.  Please review our sizing guide for more comprehensive weight instructions.  

Is it safe?

    • When used correctly, extremely safe!  From the top down we designed the K9 Sport Sack with your dog's safety in mind with a collar clip that fastens securely around the dog's neck, high density zippers and adjustment straps that limit movement without limiting the fun or compromising balance.

Is it adjustable? 

  • Yes!  We designed the K9 Sport Sack to accommodate the widest possible range of dogs by adding adjustability on multiple parts of the dog's body.  The collar, shoulders, and lumbar areas all include straps that cinch snugly around your Yorkie or expand to fit your Frenchie.

Can my disabled dog ride in one?

  • It depends on the disability and condition of your dog.  Please consult with your veterinarian before purchasing to ensure the K9 Sport Sack is right for you.
