So let me begin with explaining the title of our review... our female corgi hates anything new. She has crazy corgi phobias like hating being brushed, don't touch the paws, no new collars, no new leashes and heaven forbid a harness. But she has a gimpy paw and we don't have the heart to leave her home. We have carried her without a pack for miles and even at just 24lb, this is exhausting in summer heat. Lately, she seems alot more sensitive to gravel trails or uneven pavement and any debris underfoot, so we knew this was the only answer. So with the help of their amazing customer service, we were able to find one in stock in the right size and color. When it arrived, Little saw it and ran. So we thought great, there goes $100. WE WERE SO WRONG! Lol.
We took our 4 dogs for a hike and brought it and she started hurting and we figured this is the big moment... we unzipped it, showed her where to put her little paws and zipped her in. We adjusted all the cinch straps to lock her in and SHE LOVES IT! She settled right in like it was made for her. The smile on her face was the best only to be topped by her nodding off sleepy because she was so comfy. When we got back to the car, she didn't want to get out of it and opted to stay in it and sleep in my lap while my husband drove home.
Our corgi is 24lb and not super long. But we also have a male corgi who is 30lb and at least 3-4 inches longer than her, so we ordered the Plus 2 size large.
My husband is a tall and muscular guy, so he was struggling a bit to get the straps adjusted comfy and not have her slide down his back some. I on the other hand am only 5'5 and not muscular at all and I had no trouble keeping her in place.
Like any pack, you do have to get used to having the weight on your back and shoulders, but the shoulder straps are very well padded and definitely help with that strain. Today our hike was hot, almost 90 by the end, in the hot CA sun and she was still comfy as all can be and I was good. My back still sweat because I'm human, but the pack is well ventilated to allow some cooling.
I think the only thing I am feeling like I'm missing is a lower strap around my waist to help keep it positioned well. There is one that clips across the chest which is a super help, but I feel like a lower one would be helpful as well. But it's great as is. Also, the extra removable smaller gear pack is GREAT! There's room for lots! I was able to carry a 2 liter bottle of water, a collapsible bowl, dog cookies, poop bags, car keys, cell phone, balls, extra face masks, small first aid kit. It's plenty of room for anything you need to bring, but just also remember that this is clipping on too, so it is added weight.
All in all, this is a great pack and if Little loves it, your dog will love it too. We cannot believe how easily she took to it. Like a baby in a bunting. Thank you K9 sport sack!

My puppy is so happy in his little bag. We go cycling, walking and exploring. He's just little so when we go for walks and he gets tired I just pop him in the bag and he's good to go. The first 3 or so times he was a bit fidgety getting in, but now he's happy as larry.

my dog is slowly getting older and his energy levels aren't what they used to be, so i started seriously looking into this bag. i did a lot of research on this bag before i bought it. i read all the reviews, watched all the youtube videos, compared all the different models. like everyone else who has bought this bag, it's because my dog is my everything and i wanted to be sure that this was as safe and secure as possible for him. plus at $100, it's an investment!

after over a month of using it now, i can happily say that this bag is worth the money. you can tell it is well-made with high quality materials. my dog feels incredibly secure inside of it and just as important, he is comfortable in it. my dog has gone through a lot of different bags--baby slings, bags for the airport, etc. he hated all of them! he would fidget and move around to try and get comfortable, and it would stress both of us out. but in the k9 sport sack, he doesn't do any of that. he feels tight and secure and comfortable, even with the extra bag strapped on top of him. i like the mesh on the sides--even on sunnier days, he doesn't feel too hot (another problem i've had with other bags).

i got the plus 2 because it comes with the extra bag (perfect for water, dog and human treats, wallets, phones, etc) and because the straps are thicker and more padded. like the website says, this model is better suited for longer adventures. my dog is only 12 lbs but i'm glad i got this bag even just based on the straps alone. i haven't tried the air, but i imagine the pads on the straps make a huge difference! my shoulders/back are grateful.

not many of the other reviews i read acknowledged this, so let me just say very clearly that depending on your dog, it will take some time to get your dog adjusted to the bag. it is definitely a new position for their body (at least for my dog). my dog was very resistant at first (he likes to be free!) and it took a while for us to bribe him into getting in the bag (the youtube videos that k9 sport sack has are very helpful and i'd highly recommend them), and honestly even now (after a month). when i say a while, i mean we practiced for a while before even taking him on a hike. my dog is old so introducing new things into his life is a slow, steady process. he is still not very happy about being in the bag; that being said, however, he TOLERATES being in it! which is HUGE for my dog! just knowing my dog, i figured that he wouldn't be like some of the other dogs featured in the review who love their bag, but even my picky, stubborn, proud, senior dog can tolerate this bag because it's comfortable and he feels safe in it. so that's good enough for me. maybe one day he'll love it!

one small thing is that i didn't like the huge velcro on the bags; it feels like getting a patch is mandatory since if you don't have one it's just a huge velcro on both the attached bag and the actual bag. but this is small.

TLDR: this bag is high-quality, safe, and worth the money, though you have to put the time and energy in to helping your dog get used to the bag. even a stubborn and proud dog like mine will eventually tolerate this bag! and hopefully one day he'll love it as much as i do.

We love to take Cooper everywhere with us but he is a little guy and tires out quickly. This is our second K9 sport sac and we love the improvements on this model, a better zipper and the extra storage space is a game changer. Excited for more adventures with our posh pup riding in style.

The K9 Sports Sack Air2 is amazing. Our small dog is getting up there in age but still loves hikes. With the bag she is able to come along but not walk the whole time. It's the first dog carrier we've found that is super comfortable for us as well!
