## Description

desertcart.com : K9 Sport Sack Plus 2 - Small, Summer Mint | Ideal for Dogs with 13-16" Back Length - Adjustable, Backpack-Style Carrier with Removable Storage Pack : Pet Supplies

Review: Makes it possible to take my dog with me on my bike - I bike a lot for transportation and for fun, so when I adopted a dog I was trying to come up with a way to bring her with me on my bicycle. I found that most dog carriers and backpacks are meant for small dogs, maybe 20 lbs max, and she is 38 lbs. Then I found the K9 Sport Sack, and I got the Air Plus because it is the only version rated up to 40 lbs (the Air and the Urban are up to 30). Now I'm glad I did - the detachable storage bag (I don't have it on in the picture) buckles easily on once I have my dog in the backpack and holds everything I need: leash, food, water, bowl, wallet, phone, bike lock, etc. The Large fits her well, but I wouldn't put a bigger dog in it. I'm not sure that every 38-lb dog would fit, either, but she is lean and long-legged, and within the recommended measurements. I definitely struggled the first few times trying to figure out how to get her into it and get the backpack on my pack - fortunately I have a patient dog! In order to get her in, I lay the bag open on the floor, put my hand under her chest/between her front legs to lift her up and feed her front paws through the arm holes, buckle the bag around her neck, then scoop her rear up and tuck her into the bag and zip it. As far as I can tell, she loves riding in it and has her nose in the breeze the entire time. She adjusts herself every now and then and sometimes leans to the side, but she doesn't wriggle at all; even if she did she is secure. The only thing is, she does get quite heavy after a while! It would be awesome if there were some way to add a hip belt like a backpacking backpack has, as having 40 lbs on my shoulders is a lot after a few miles, but I can see why the backpack doesn't have one because even with the size large it sits a little above my hips. Overall this is a great solution, the backpack is well-made and allows me to take my adventure buddy with me!
Review: Well constructed - Very well constructed. I felt very confident that it was secure. My 18lb King Charles cavalier fit.

### ⭐⭐⭐⭐⭐ Makes it possible to take my dog with me on my bike
*by I***L on July 26, 2019*

I bike a lot for transportation and for fun, so when I adopted a dog I was trying to come up with a way to bring her with me on my bicycle. I found that most dog carriers and backpacks are meant for small dogs, maybe 20 lbs max, and she is 38 lbs.

### ⭐⭐⭐⭐⭐ Well constructed
*by D***S on August 29, 2026*

Very well constructed. I felt very confident that it was secure. My 18lb King Charles cavalier fit.

### ⭐⭐⭐⭐ Novel Concept, Worth the Price
*by K***N on April 14, 2020*

I love the overall concept. My dog fits in it PERFECTLY. She's a very small Westie, only 11 lbs., but solidly built as Westies are. She loves going in the sack, as she is quite arthritic but loves to go outdoors. I love the backpack that allows me to stash our supplies for hiking. My complaints are as follows: 1) the backpack attaches to the sack awkwardly and my supplies rattled against the sack, no matter how well I secured them. 2) the little backpack should have had a separate strap so that it can be worn alone. 3) the straps have to be tightened very tight to keep my dog riding up high on my shoulders. Even so, I felt like I was constantly hiking the bag up, as it was really pulling hard against my shoulders (for reference, I'm 5'2", 155 lbs., hit the gym 5 days per week, can lift fairly heavy, high reps, and I run outdoors). My lower back hurt pretty bad after a 2 hour, 4 mile hike, during which time I carried my dog on and off-- approximately 75% of the time. I look forward to using the bag again. I think some of the design flaws will be improved with time, as this is an excellent concept and the best bag I could find for the money. Side note: I ordered custom patches from the K9 website to complete the bag (they're awesome). The bag comes with a velcro strip to secure the patch, and looks dumb without it. ETA: I got many, many uses out of this bag and my dog enjoyed it, too! Have recommended to friends and family.
