Nice, good quality bag.
So the pros to this bag are that it fits my nearly 30 pound obese pug in it. And he looked very comfortable in it. Haven't found a lot of bags that can hold that big of a dog. He's very tall also for a pug. I had to order the large, but it fit and he wouldn't get out of it when I put him down on the ground. The cons are that it's not that easy to get the dog in, at least for me, yet. I've only used it twice however. And it was difficult the first time, to get the dog in and be able to zip it up, the second he was in pretty quickly. I feel like for me, I need someone to help me hold the bag up around their legs while I zip it. At least until I'm better at it. I actually bought this bag for my other pug who is very arthritic and old and cannot walk very far because I want to take her to some trails so she can explore and smell before she's unable to walk at all. Haven't put her in it yet because I don't want to mess with her legs too much until I'm actually taking her someone, but I know she will fit now. The only question I have about this bag is that the bottom is narrow so the dogs butt/back end/legs really wouldn't have much room it seems like to be very comfortable. And since their back legs have to stay in the bag it just seems to squished up to me. Not sure if they would be hurting after being squished up like that too long. Also if the dogs not light weight it's definelty going to be hard to carry them. I know I won't make it far with my dog in the bag, but that's okay, the bag does serve the purpose. And the quality does seem really good.

The best option for your chunky baby!
I have tried so many different carriers for my 22lb pug but this is definitely the best option! You'll need a size Large if you have a barrel chested pup like a pug or frenchie. As several other reviews have stated, I have to put a rolled up towel in the bottom for his butt to rest on because the Large is long, but the width is necessary for his little ham body. It's a bit awkward to get him in there- it goes on kind of like a harness with front legs out, but the back legs go in the bag, so he gets a little wiggly. It's much easier to put on if you have help! You also can't really set the bag down with the dog in it. But once he's in, he's very happy- we hike all over with the dogs to get to rock climbing routes and so far the bag has been great! If you are going a long distance, it does put a lot of pressure on your shoulders since there is no belly strap. However, overall, it works well and puggy seems to enjoy coming along for the ride with no effort. Happy hiking!

Stop scrolling and buy this now!
This is literally the most amazing product ever! I have 3 other carriers and a stroller for my 12 pound passenger princess and this is my go to as in I keep it in the car and never go anywhere without it. Need to run into the store quick but have the passenger princess in tow? No worries, toss her in the sack and in you go. This works on every store everywhere that does not allow dogs, if the employees notice, they’re too taken aback by the adorably cute doggo strapped to your back to care - I’ve literally had employees want to pet my dog in a no dogs store. The main thing that makes this my favorite carrier is that it evenly distributes the weight and the dog leans into your back so there’s no added intermittent weight from a booty shift and wiggle even when hiking 5+ miles. I will not hesitate to purchase again should anything ever happen to the current one but it seems incredibly well made. With all this said, I feel it’s also worth noting that my passenger princess loves to be carried, held, or pushed in a stroller as in god may strike her dead if her dainty little hands aka paws ever touch the desolate earth, so if your dog is not a fan of being held this would probably not be the best to start with as it is very form fitting to the dog and human alike…but if you have a Velcro fur baby I simply cannot recommend this enough as in an infinite amount of stars - and no, I did not receive anything for this review, it really is just this amazing!

She seems happy with it.
After wrangling her in to the backpack she seemed to like it, and let us put her in it again. For that Ali e we’ll give it five stars. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️

Best carrier for dachshund! He doesn’t like walking so this backpack is super convenient and comfortable for carrying him!

It’s okay
I received it today and tried it out on a five mile walk with the new puppy. All in all I like the concept and the dog seemed pretty secure. I ordered a size up, knowing the pup will grow fast. I cut a couple styrofoam pads in the bottom to help with fit. The pup did great, no squirming or whining. She just chilled the whole time. There are a few issues, first is the buckle on the chest strap. First time I tried to buckle it, it broke. The buckle appears pretty cheap. The second, knowing the pup will outgrow this quickly I went with the mid-grade one. The pup is 13 pounds now, once she hits the 20 pound mark the shoulder straps will dig in too much to be comfortable. The third, every mile I had to tighten up the main straps, the ones adjusting the height it rode. At one point I lost 3” of strap. I thought I might return it but knowing my pup will out grow it soon I’ll just hang onto it.

Take your time and follow the instructions
This is great. The step by step instructions were easy to follow and worked the first time. Great for travelling in ferries and walking through country markets where small dogs feel like they are going to be trodden on. Quality is great and he feels very secure especially with the back supporting straps.

Perfecto y seguro
Excelente artículo, muy buena calidad y resistente. Mi perro va cómodo y seguro. Tardo un poco en llegar y hubo confusión con la mensajería. Pero fuera de ello estoy muy contento.

Caution…DO NOT PURCHASE
The rucksack is okay but please be absolutely sure you know what size you need as for some reason you can’t return this item. Very, very poor Amazon, I will now rethink my future purchases.

Probably good
Could not physically put my 20 lb. Dog in the backpack by myself. I travel solo so without help from someone else I would never be able to manage to get my dog hoisted onto my back.
