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 ❤

Great design! Very pleasantly surprised. Thank you K9 Sport Sack!

My two dogs and I live for our daily walks in our hilly neighborhood. Gracie, the older of the dogs, is at least 13 years old and is struggling with arthritis. When the vet limited her walks to bathroom breaks only in October, I moved her to a large, sturdy dog stroller that I had bought for her earlier for longer walks, but she was so tense in the stroller that even walks in the stroller seemed to leave her sore afterward. Thus, we all stopped going for walks in accordance with the vet's instructions. I didn't have the heart to take my other dog for walks and leave her at home day after day.

After seeing the K9 Sport Sack Rover, I decided to give it a try, fully expecting that it would not work for one reason or another--either I wouldn't be able to carry Gracie's weight, or Gracie would not like being in a backpack, or it would leave her sore, or all of the above. But after watching the videos and examining the design carefully, I bought Gracie a Rover for Christmas.

To my happy surprise, Gracie seems to be really enjoying her Rover! Gracie seems comfortable in the Rover and she is very snug and secure within it. Even when I bend over to put on my other dog's harness or scoop up after him, Gracie seems comfortable and calm. She doesn't exactly jump in the bag on her own or anything, but she does not fight being put into it. The first couple of times I put her in it, she trembled a bit at first (not an unusual response for her), but once we got out on the street and started walking, she immediately stopped trembling, relaxed, and focused on checking out all of her surroundings. Gracie seems to really enjoy the high vantage point. When she gets out of the bag, she does not exhibit any additional soreness. And because we are able to go for daily walks again, she is perkier and more joyful all day long.

The design is great. I knew in buying it that it had several of the same features as my high-quality camping backpack, and Gracie--at about 40 lbs--is similar in weight to my camping backpack when packed. In practice, the Rover works very similarly, and I have been able to carry her comfortably up and down the many hills in our neighborhood, despite not being super athletic. It feels like a daily workout--energizing but not too much.

Many thanks to K9 Sport Sack for coming up with this design, which has made it possible for us to resume our daily walks!


We bought this backpack in anticipation of a flight we were taking and trip we wanted to include our dog on. Unfortunately our backpack arrived with a problem that wasn't going to be able to be fixed before our trip. I contacted customer service and let them know about the issue and the trip. They were quick to respond and told me to contact them after we got back and they'd replace it. When we got back I contacted them and as previously promised they got a replacement in the mail and sent me a return label to send back the pack we had. It was very quick and painless.

During the trip our dog, Scotty, was nice and snug and comfortable. She was a hit at the airport and people constantly stopping and taking pictures and asking us about our backpack. She rode in the backpack at our feet and handled the plane very well. We are looking forward to using the backpack for hiking as well. She's right around 30 pounds. We did buy a block to go with this to help her be more comfortable.

Wonderful purchase.

This turned out to be a wonderful purchase. My daughter was preparing to fly to California right after Christmas. Her Pittie, Leo, is her ESA and the airlines was requiring something to keep him confined. He's obviously too big to be in a carrier sitting in the space beneath the seat in front of her. I was a little concerned about how on earth she would manage to get him into the backpack and keep him there, not to mention carrying him. And I was really hoping the flight was not full so she could possible spread out a bit.

It was Leo's first flight and since he doesn't like car rides very much, we were concerned about how he would handle a flight. He doesn't like take-off or landings but hey, not too many of us humans enjoy them either. He did great and it turned out to be a terrific travel experience. It appeared that everyone loved to see the K9 Sport Sack. Pics were taken through out the airports she was in and people came up to talk to her about it and her dog. Free publicity for your product! Hopefully folks who were interested will follow through.
