Best puppy carrier
The best carrier for my pup. Sturdy but comfortable

Nice and Sturdy. Does the job.
We needed a slightly larger one, but needed overnight delivery and size M was the only size that was able to deliver overnight. We ordered size M anyway and it worked fine for the occasion, but wished we could've selected a size L overnight. This product came in good condition and help our 25 lbs 2y old Corgi through rough terrain hike at Nambe Falls, NM. It fits her real snug. She didn't cry or show any signs of discomfort. Although, she can use a little more room around her upper shoulders. She is full grown and we will continue to use it as much as we can.

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!

Our dog LOVES this backpack for bike rides
We LOVE this backpack for our dog. We got size Medium for our English Cocker Spaniel and it is literally perfect. He is very comfortbable in it and as soon as we get it out of the closet he tries to get inside of it. He loves it so much!

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. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️

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.
