    Awesome adventure carrier for your best friend!

    I love the K9 sport sack plus 2 I purchased! It’s a great carrier for your dog and you. I use it to go on bike rides and it’s comfortable for both the little guy and your shoulders and back! I like being able to turn my head and see that he’s doing all right and he definitely seems much more comfortable in this carrier than others I’ve tried. Awesome product!

    Top Notch!

    The bag alone is great, a comfortable fit for both me and my little dude! I could not have been happier with the service from the team over at K9 Sport sack. I purchased the small bag and upon attempting to get our dog into it realized the medium was the better fit. They quickly were happy to accept a return and ship out the new bag and we had it before we knew it. Really appreciate the flexibility and response from the team. Very happy overall!

    Great customer service

    When I received my order, the clip was broken. I emailed them, and filled out the form. Right away they shipped out a new one. I had my new one in a couple days. Sadly I have not used it with my little guy 🐶 due to his injury… why I didn’t upload a video😔 but I can’t wait! The backpack quality is great! ⭐️⭐️⭐️⭐️⭐️ Thank you!

    Hiking Trip

    Absolutely loved it. We were able to go on longer hikes with our 8 year old beagle. She was happy to see the backpack when we she slowdown on the hikes. Also, we were able to go on hikes where we encountered boulders, stairs and chains, the backpack made it possible for us to continue with our pup.


    Backpack quality is great.
    Customer service is great.
    5 stars!
