About K9 Sport Sack

K9 Sport Sack Review 1

Not all dogs are built for your wildest adventures, but that doesn’t mean you have to leave your four-legged best friend behind! This K9 Sport Sack review will tell you everything you need to know about the brand that sells veterinarian-approved backpack-style dog carriers for you and Fido. 

Dubbing themselves the “original backpack dog carrier,K9 Sport Sack has been mentioned worldwide in publications like Forbes, BuzzFeed, ABC News, and Cosmopolitan. They also have a strong social media following with 129k followers on Instagram

In this K9 Sport Sack review, I’ll take an in-depth look at the brand and its products, customer ratings, promotions, and more, to help you decide whether or not their products are really worth the buy. 

Overview of K9 Sport Sack

K9 Sport Sack Review 2

Co-founders Joseph and Jennifer Watson were inspired to start K9 Sport Sack when they rescued a dog who had been abandoned in a trash bin.

After “Dumpster Daisy” (eventually shortened to just “Daisy,” for reasons I hope are obvious) recovered, they began looking for backpack carriers so she could join in on the fun instead of being left home alone.

Out of the various styles they tried, none of them seemed to give Daisy a comfortable ride. Finally, Jennifer created the solution herself, using nothing but her sewing machine, some fabric lying around, and the straps of an old bag. Little did she know that she’d just made the prototype for something countless other dog-owners were looking for.

K9 Sport Sack is located in Utah, where they continue their mission towards a world where there is “no dog left behind.” All products are made in the United States. 

Up ahead, I’ll steer this K9 Sport Sack review into some of the highlights of shopping for this dog carrier brand.

K9 Sport Sack Review

We want our dogs to join us while traveling and hiking, but it’s important to prioritize their health and wellbeing. The K9 Sport Sack features a variety of backpack-style dog carriers that are comfortable for your four-legged travel companion. Let’s take a look at the brand’s best-selling products. 

K9 Sport Sack Air 2 Review

The K9 Sport Sack Air 2 is probably the brand’s best-known product. This Sport Sack is perfect for dogs up to 30 pounds and are small to medium size. 

Available in an assortment of different colors, the K9 Sport Sack Air 2 has adjustable mesh side panels that allow your pup to regulate their body temperature, and the breathable fabric of the sack helps avoid overheating. 

The spacious base means there is lots of room for your pet’s bum and tail, and the various cinch straps allow for easy adjustment.

Nothing makes a person’s day like seeing a dog riding in someone’s backpack. With the K9 Sport Sack Air 2, you can be that someone for $75.

K9 Sport Sack Plus 2 Review

If your medium-sized dog weighs closer to 40 pounds, the K9 Sport Sack Plus 2 is the dog carrier for you. Like the K9 Sport Sack Air 2, the Plus 2 has customer favorites like the fully ventilated side panels, spacious base, and cinchers. 

The Plus 2 features a padded back panel, which helps balance the extra weight of your dog. There is also a detachable storage bag which is great for those who need room for gear. 

The K9 Sport Sack Plus 2 is currently listed for $95

K9 Sport Sack Rover 2 Review

Do you have a big pup that loves to join for hikes but doesn’t quite have the stamina for your adventure? The K9 Sport Sack Rover 2 is built to help carry your medium to large size dog. Alternatively, if your four-legged friend is built like an athlete, you can use the Rover 2 as a 60-liter backpacking bag.

The Rover 2 has an 80-pound weight limit and a removable lap belt to help distribute the weight. The pack has a detachable sun and rain hood to keep your dog comfortable. Convertible storage doubles as back support for your dog too. 

Regardless of your adventure companion’s fitness and physique, the K9 Sport Sack large Rover 2 gets the job done for $265

K9 Sport Sack Klearance Rover Review 

I hate to see good products go to waste due to something insubstantial. Sometimes we as consumers get so wrapped up in choosing form over function, we miss out on a great deal!

That’s why I love that K9 Sport Sack has a clearance section for selling items as-is, including this K9 Sport Sack, Klearance Rover

The carriers in the “klearance bin” are sold there due to minor imperfections or refurbishment. And don’t worry: all these defects are purely cosmetic. The actual integrity of the Rovers are all up to snuff. Some of them are even perfectly good display items who’ve seen the end of their modeling days.

This particular dog carrier may have once been called the K9 Sport Sack Corgi Edition as it’s the perfect size for medium to large dogs with a 30 – 80 lbs weight limit. Have you ever seen a corgi in a backpack, bouncing behind its owner’s head like a smiling loaf of bread? It’s instant happiness.

At the time of this K9 Sport Sack review, I found the Klearance Rover for only $153 (down from $180). 

K9 Sport Sack Trainer Review

Are you ready to introduce your four-legged best friend to the backpack carrier life? It’s time to talk about the K9 Sport Sack Trainer

The Trainer carrier is available from sizes extra-small to large and is perfect for teaching your pup about the outside world. Meant for shorter activities like neighborhood walks and public transportation, the Trainer holds up to 30 pounds. 

If you and your best friend are ready to put on the training wheels, the K9 Sport Sack Trainer is only $50

Is The K9 Sport Sack Safe For Dogs? 

K9 Sport Sack Review 9

Yes, K9 Sport Sack is completely safe for dogs and has been veterinarian approved. The brand puts their products through various testing stages to ensure that every product is safe. 

Who Is K9 Sport Sack For? 

K9 Sport Sack Review 10

The backpack-style dog carrier is perfect for active dog owners who want to bring their four-legged companion on their hikes, bike rides, and travels.

Whether you want a K9 Sport Sack Air Plus for your medium-sized dog or something that will keep your tiny pup safe, the K9 Sport Sacks are ideal for dog lovers who want to include their furry friends. No more dragging your dog behind you on a leash, and get back to enjoying the adventures with your best friend. 

Comparison: K9 Sport Sack vs. Kurgo

K9 Sport Sack Review 11

Kurgo is a pet brand that specializes in dog travel products, from carriers and backseat barriers to harnesses and outdoor gear. Like K9 Sport Sack, this brand started from a family creating an innovative solution for their dog’s travel needs, this time riding in the car. 

The brands are pretty similar at first glance. K9 Sport Sack and Kurgo are focused on dogs’ safety and wellbeing with products tailored towards active pet owners. They both ship internationally and accept returns for unused products.

But K9 Sport Sack focuses its brand on backpack-style carriers first and foremost, with other doggy travel essentials like goggles, tents, or water bottles on the side. Meanwhile, Kurgo is all about car safety, with a wide assortment of carriers, barriers, and covers for safe travels, all with a lifetime warranty.

Then again, K9 Sport Sack’s signature carriers are substantially cheaper than Kurgo’s options while still offering the best in comfort and safety for you and your pet.

It’s a close call since these are two great brands that prioritize our furry friends over all else, but if you just want an easy, straightforward, affordable backpack-style dog carrier, the K9 Sport Sack could be the brand for you.

K9 Sport Sack Reviews: What Do Customers Think?

  • K9 Sport Sack Knavigate: an average of 5/5 stars with 49 reviews 

There seems to be an overwhelmingly positive response to K9’s backpack-style dog carriers. If we take a closer look at the K9 Sport Sack Plus 2, one of their most popular carriers, one happy customer left a 5-star review about how well it works for her senior dog. She said: 

My senior citizen loves it! She is 16 years and can’t make it on the long hikes with her other pup siblings. Well made, durable. Only wish I could get the block support as I got the M pack and for now just putting towels and such to give her more support at the bottom until the M/L blocks become available!”

Another happy customer left a K9 Sport Sack review on their Facebook page celebrating how it fits seamlessly into her and her dog’s active lifestyle. She said: 

“I have to say absolutely the best K9 backpack ever — Lucy my dog and I love it. Our 1st bike ride together and she loved every bit of it. I’m also very impressed with the  Customer service I got and the help and all the  Helpful advice too. and I live in Australia QLD and the delivery was super fast too. thank you so much guys we love it next is getting a name patch to add to the backpack.”

Several customers have left positive K9 Sport Sack reviews regarding their stellar customer service on various websites. Even when customers experience an issue with their order, the customer support team has been efficient and helpful with correcting matters. 

One customer left a review on TrustPilot recommending K9 Sport Sack for cycling with your dog. They said: 

“My dog and I recommend the Rover sack. I bought a Rover sack so I could take my bulldog on cycles. It is a nice rucksack, my dog is safely lodged in it and she can come along. The waste belt came loose the first time we used it, so I complained to the company. They sent me a new Rover free of cost! We haven’t had any problems with it and I was impressed by their customer service.”

One recurring issue mentioned in several K9 Sport Sack reviews is the fees associated with international orders. One customer left a review on Amazon about extra charges and said: 

Great product but the brokerage fees to get this to Canada are outrageous. Should ship USPS not UPS. Canadians beware!”

Overall, there aren’t many negative K9 Sport Sack reviews on the internet, except those that warn of extra charges for international shipping — Canada included. Most people are thrilled with their backpack-style dog carriers and recommend the brand to active dog lovers.
