 Customer Reviews

Is it comfortable for my dog?
  • Yes, very comfortable. Your dog is ergonomically positioned in the K9 Sport Sack in a way that there are no hard pressure points anywhere on their body, not even their legs. They're essentially in a sling with their weight distributed among the entire bag. There is also a rest pad at the bottom of the bag adding extra support for your dog.  It can easily be worn for an hour or more at a time. 
Is there a weight limit?
  • The K9 Sport Sack will safely carry any dog up to 30 lbs (Anything over 30 lbs voids the warranty, although heavier dogs may fit)

Is it safe?
  • Extremely safe. When we designed the K9 Sport Sack, safety was our #1 priority. There are straps everywhere that adjust perfectly with a no slip clip collar clip and D-ring hookup on our AIR models to ensure your dog cannot jump or fall out of the K9 Sport Sack. 
Is it adjustable? 
  • Yes. There adjustable neck straps, side straps, chest straps and shoulder straps that are all adjustable for the perfect fit.
Can my disabled dog ride in one?
  • It depends on the disability and condition of your dog. Consult with your veterinarian first before buying if you have a disabled/injured dog. 
Is the K9 Sport Sack Washable?
  • Yes. The materials are hand and machine washable. Just make sure to hang dry and use light detergent
