Backpack Made for Ruff Adventures

I have not used it yet but my 55 lb pit bull mix fits in it quite well. The materials are made of high quality and I feel it will last a long time with many uses. I bought it to take my dog with me on motorcycle rides and I am sure I can find other uses for it too. I am looking forward to using it!

Love the Rover bag

I initially tried the Sportsack, which was quite difficult to get Paulie Walnuts into and didn't provide enough support. The Sport Plus bag worked pretty well, but I missed a waist strap and some internal supports to provide more comfort for myself and Paulie. The Rover bag has been perfect in that regard. It's easy to get him in and out, it's much more comfortable to wear and gives him better support with the internal frame and better padding, and all the extra compartments are very helpful. The bottom storage space would be useful on longer trips, but it does make the bike quite large and bulky for shorter bike rides and hikes. Given the choice I would've liked to be able to detach that. But other than that it's been perfect and Paulie Walnuts really likes riding in it.


This Rover is amazing for our husky mix Lola. She was very timid at first but seemed to be more curious than anything. She fits perfectly in it. I couldn’t ask for a better design. I am 5’2 so I was a little worried if it would fit me since it is a large but it will accommodate to anyone of any heights needs. Thank you guys so much!

Happy pup, happy parents!

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.

Two Paws Up!

Gumbo is typically a squirm worm and always wants to be on the go. Some medical issues have really limited his endurance and this is such great option for him. To my great surprise, he took to the SportSack very quickly and seems comfy and content to let me do all the work. The sack itself seems to be great quality and is user friendly. I'm 5'9" and think it sits fairly comfortably with some room for adjustment in either direction. I cannot overstate how much I love hearing him sniffling/snuffling in my ear and pointing at all the squirrels with his free paws in true Viszla fashion ❤
