Who Are K9 Sports Sack?

K9 Sports Sack was created by Joseph Watson with a little help from his dog Daisy in 2010.

When preparing for a bike ride, Joseph placed a drawstring bag on the ground and was surprised to see Daisy lying face down on the bag looking to accompany him.

This was the start of the K9 Sport Sacks as Joseph set about designing one of the world’s most popular pet carriers with help from his wife Jen and his willing tester Daisy.

One year later, the first professionally manufactured K9 Sports Sack was complete and sent to their initial batch of customers who revelled in the invention.

K9 Sports Sack continued to create different types of carriers to accommodate dogs of all sizes, whether it’s wide-shouldered Corgis and Frenchies, or slim and skinny pups like my Klee Kai.

Designed for hiking, biking, cycling, skiing, snowboarding, commuting, shopping and much more, the K9 Sports Sack can be found on the backs of dog owners in many countries around the world.

As of 2021, K9 Sports Sack have eight different models to cater to pet parents and different dog breeds. You can even customize your K9 Sports Sack with name and breed patches.

Your preferred pet carrier will depend on what function you want your K9 Sports Sack to serve. Do you intend to use your K9 Sports Sack for commuting to work on the train, subway or underground? Are you planning to use your K9 Sports Sack for challenging bike rides or hikes in the mountain?

K9 Sports Sack outline on their website that each of their carriers come with standard features.

There’s a carabiner that you’re able to clip to your dog’s collar to provide extra security.

K9 Sports Sack have a no-slip zipper to support your dog’s back and ensure they’re stable on your back.

Their website goes on to explain that they use angled side cinch straps to keep your dog in a forward position.

You’ll notice that their carriers have a collar enclosure at the top of the bag to keep your pup snug and safe.

If you’ve seen dog owners using K9 Sports Sacks on social media, you’ll immediately identify the mesh on the side to ensure breathability and ventilation.

Here are some things you’ll want to consider when you’re weighing up which K9 Sports Sack to buy.

Customer Reviews

The Knavigate carrier has 18 five-star reviews and five four-star reviews out of 23 total reviews on their website.

Leslie explained how the Knavigate has helped her senior dog.

I initially ordered this bag for extended hikes with my senior dog. He recently tore his ACL and is awaiting surgery, and this bag is what’s letting him get outside until then! It’s incredibly well made and thought out. I wasn’t sure what 38 lbs. would feel like on my back as I’m a very petite person, but the bag is extremely comfortable to wear. My sweetie seems so comfortable in it and getting him in and out gets easier each time.

Denise explained some of the added benefits compared to the Trainer.

The Knavigate is a great upgrade for us from the “trainer”. The added support around the waist makes the carrier feel more secure and our dog seems to sit higher so she can look over my shoulder easier. We LOVE K9 carriers and highly recommend them!


The Knavigate is available to purchase Amazon and costs $164.95 for US customers.

Our Verdict

Having initially started my K9 Sports Sack journey with the Trainer model, I was impressed with the hip and waist support of the Knavigate.

As someone who likes to go on long hikes with my Alaskan Klee Kai, I felt the Knavigate was extremely comfortable to wear.

My female Klee Kai Skye was safe and stable in the bag without a booster block (which I previously required with the Trainer) and I found the Knavigate provided excellent support for my back and shoulders.

If you’re looking for a versatile pet carrier that can tackle all manner of activities, The Knavigate could be the perfect accessory for you.

Caitlin explained her senior Dachshund loves life in the Trainer.

Dobby is getting older, and sometimes he doesn’t want to hike quite as far as I do. The medium K9 Sport Sack fits him perfectly, and he seems to genuinely enjoy being in it. It’s also great for days when I need to take him to work with me or to any sort of event where having him on a leash is inconvenient. I’m so happy with my purchase!

Christine loves the lightweight feel of the Trainer.

Both of my dogs loved riding in the trainer! At this point they are pros because this is our 4th K9 sports sack! As the person carrying them, I love this product because it has all of the same great features as a normal K9 sports sack, but just the necessities and no extras or frills which is perfect because it makes it light weight and easy to bring with me everywhere! My trainer bag is size large and both my Corgis fit into it!


The K9 Sports Sack Trainer is priced at $54.95 for US customers.

Our Verdict

My first K9 Sports Sack carrier was the Trainer. I’m really pleased I decided to start with this model because it was ideal to get my Alaskan Klee Kai acclimatized to life in a carrier.

It’s lightweight design made it easy to use when I had to travel with my mini husky on the London Underground, while still having some of the little additions store leashes and treats.

I thought it was perfect my Klee Kai when they were puppies blossoming into young adults, before they finally outgrew the Trainer and required an upgrade!

Not only is the bag functional and comfortable for both users but my dog LOVES it! The second we got it she jumped right in (granted at first I think she thought it was a new harness) and now she can easily go everywhere with us! Minnie’s favorite part is the view from above -she wanted y’all to know. Can’t wait to purchase our next one for a summer fun alternate!

Marco shed light on the freedom that the Air 2 has provided to his dog.

This thing is so great! Our dog (Chippies) loves to go on adventures! Loves to hike, run, ride but we don’t like to always have to drive there. This allows us to ride to the park or anywhere else for that matter anytime. He took to it so fast! Besides the getting excited and jumping out of it, once he’s in he’s ready for our ride. We got the sport sack in Large. Our dog is a 25 lbs. half dachshund half black lab. Fits him perfect!

Alfredo described the Urban 2 as a game changer.

This is a game changer. Best investment if you live in the city and you can start your dog early to get used to it. He fits comfortably, it’s pretty easy to put on and feels super safe. Really useful for getting around in the subway / public transportation. Great material. Definitely an amazing purchase.

Rebecca was delighted with the Urban 2.

I bought this SportSack for my senior terrier mix after seeing other dogs traveling comfortably in Sport Sacks around town. I wasn’t sure my dog would like it, but in just a few short weeks he has become very comfortable in it! We just got back from a 10-mile bike ride, and last week we took a historic walking tour, both while using the SportSack. It’s comfortable and secure for my dog, and he gets so much attention when he’s riding around on my back, he loves it!

Customer Reviews

Of the 79 reviews of the K9 Sports Sack Rover, 69 are five star! That’s a lot of happy dog owners.

Ryan gave the Rover a five-star review based upon their experience with their Beagle.

We used the K9 Sport Sack to bring our 55 lb 1 year old pup from Brooklyn to central park via the subway. While it’s a little tricky to get him to sit on it to begin with he’s getting the hang of putting it on and it seems to be pretty comfortable for him (as long as he has a steady stream of treats and pets). For the person, the pack is super comfortable and well made, it’s easy to wear for a bit and our pup was secured even when other dogs walked by and got hime a little excited. Also, props for making a backpack for bigger dogs, hard to find but I’m happy we did.

Rachel felt the Rover 2 was worth every penny.

At first I was hesitant to buy this backpack because the price but it is totally worth it! Even though this is made for hiking it was AMAZING to bring my dog through an airport with it. Kept her calm and made the trip overall easier for me. The quality is amazing and my dog fit right in although it was a bit tricky getting her hind legs to stay put. I got the size L not fully reading the description- I have a 45 pound Border Collie/ Samoyed mix. She definitely still fits but will upgrade to the XL eventually.
