There is no one perfect method to train your dog to use the K9 Sport Sack® but we have included a few key examples on our videos page. In short, we have put over 30,000 dogs in our carriers and the more we practiced, the more dogs seemed to like being put in. Whatever method you and your dog settle on, DON'T GIVE UP! Use our Hints and Tricks and always remember to contact us for additional help or time to train your dog. It will be worth it!

The K9 Sport Sack® was developed under the close direction of veterinarians, dog trainers and outdoor products engineers to ensure the maximum comfort for your pup. He/she sits in the “begging” position which is a natural short-term stance and as long as all of our Health and Safety policies are carefully studied and followed, all the proper Safety Features are employed and your dog is healthy when going in the carrier, he/she will be healthy when they come out.

Yes! That does not mean that all dogs will take to the K9 Sport Sack® right away and it may require some training and gentle prodding but roughly 95% of dogs eventually come to love the K9 Sport Sack®. 

This breakdown is taken from our own customer feedback programs:

50% of dogs will take immediately to the K9 Sport Sack®.  

30% of dogs will struggle the first time but with patience and the right tone of voice they will go in on that first try, realize what is going on and settle into the adventure. 

10% of dogs will need some training to use the K9 Sport Sack®. Much like you had to train your dog to use the bathroom outside, some dogs will need several tries, some treats and just the right environment.

5% of dogs may require up to 90 days to become comfortable. If you are willing to try to train your dog for that amount of time then we are willing to extend warranties and offer whatever additional training and support necessary. Please contact customer support if you need additional training time.  

5% of dogs will never acclimate to the carrier. For as sad as that makes us, some dogs simply do not have the personality for it. If your dog is one of these we strongly encourage you to take the time and effort necessary to determine that.

K9 Sport Sack® uses USPS or UPS for international orders and shipping times can vary from 2-5 weeks or 3-5 days depending on the method chosen at checkout. 

• International orders are subject to import taxes, customs, duties, and brokerage fees. Your order may be held by your customs office until fees are paid. In these cases K9 Sport Sack® is not responsible for collecting/charging these fees. Therefore, it is the duty of the customer to be aware of charges that may occur at the time of delivery/pickup for imported goods. If a package is refused for this reason a refund will not be issued until and if the package is returned to K9 Sport Sack®.
• K9 Sport Sack® is not responsible for any delays in the shipment caused by invalid addresses, carrier delays, or custom duties/ taxes. If a delay does occur please contact your local post office or the carrier it was shipped with to find out more information. 

If you are ordering internationally, it is your responsibility to familiarize yourself with your country's import and customs fees. You will likely be subject to these charges that are imposed and controlled by your country and not by K9 Sport Sack®. Therefore, K9 Sport Sack® will not pay for, supplement or otherwise be responsible for customs charges. Any order that is returned because of refused customs charges will be subject to a 20% restocking fee. 

Products in stock ship within 1-2 business days. Orders with custom products can take up to 5 business days. Order notifications and tracking information are sent to the e-mail on file after check-out. If your item is backordered, you will receive an order notification after check-out indicating the status of your order, periodic updates on fulfillment status and a shipping notification when your order has shipped. 

Yes! Through extensive research and field testing we have calculated the weight limits as listed below (see each product page for more information). Although heavier dogs may fit, any weight over the listed weight limit puts undue pressure on the bag and may result in an unsafe situation. Any attempt to carry a dog over the listed weight limit voids the K9 Sport Sack® Warranty. We reserve the right to request veterinary proof of weight on any return before issuing a refund.

TRAINER - 30 lbs/13 kgs

AIR 2 - 30 lbs/13 kgs

WALK-ON - 30 lbs/13 kgs

URBAN 3 - 40 lbs/18 kgs

PLUS 2 - 40 lbs/18 kgs

KNAVIGATE - 50 lbs/23 kgs

KOLOSSUS - 80 lbs/36 kgs

The time limit is determined by your climate and activity, however on average we recommend that the dog not stay in the bag for any more than 45 minutes at a time. For hotter climates this number should decrease proportionally. For additional safety hints and policies see our Health/Safety page.  

When used correctly, extremely safe! When we designed the K9 Sport Sack® safety was our priority. A full diagram of the safety features can be found on each carrier product page.

Yes! It is still most important to select the correct size but the K9 Sport Sack® is equipped with a system of straps and clips that snuggly secure and limit balance altering mobility. Be sure you familiarize yourself with our safety features and use them to ensure the maximum safety and comfort for you and your dog. Booster Blocks are also available to lift your dog 3" inside a carrier in case your pet is in between sizes or is still growing. 

It depends on the disability and condition of your dog. Please consult with your veterinarian if you have concerns about how the K9 Sport Sack® may affect your dog’s condition. The K9 Sport® Sack was designed for healthy dogs and accepts no liability for the exacerbation of disabilities.

If put in correctly, no. There are several safety mechanisms included in the bag such as the collar clip carabiner. If the dog is properly clipped into those failsafes it is impossible for the dog to get out of the bag unaided. It is critical that none of these important steps are skipped.

No, sadly K9 Sport Sack® carriers are not yet airline approved. Dogs must be fully enclosed and placed under the seat in front of the passenger when on an airplane. However, you can use your K9 Sport Sack® carrier in the airport to be hands free while carrying your luggage. We are working on an airline approved model so check back often for product updates. On the flip side, try taking an airline carrier on a bike ride.

The sides of the K9 Sport Sack® are equipped with large gauge mesh to allow the maximum amount of airflow. At K9 Sport Sack® we are testing new cooling methods including jackets and insulators, however, currently the vents are the most up-to-date option. There are several companies that produce serviceable options for keeping your pet cool that will fit around the dog inside the bag such as cooling pads, vests, harnesses etc.

Even with these options, use prudence when carrying your dog in hot climates. Again, keep your dog hydrated and limit time in direct sunlight.

One downside to the ever-present vents is that they allow cold air in during wintertime activities. To address this we have created theK9 Sport Snuggler, a down-alternative liner that seals off the cold air, keeping the dog warm and snug inside a K9 Sport Sack® carrier.

Yes! When creating the original K9 Sport Sack® our primary concern was the safety and long-term health of our own dog so we took that model to our local vet and had him go over the ergonomics with a fine tooth comb. 

Since then we have visited a veterinarian before every subsequent upgrade and have gotten a stamp of approval before moving forward no matter how small the change. So far we have gotten the same positive response along with reinforcements of the safety information contained herein.

Yes! Hand wash with mild detergent and hang dry.
