Comfrotable enough for the dog, but the straps overlay oddly, causing a little discomfort when using. Still would buy again.Got this so I could take my dog out for rides on my scooter. She does her happy dance when she sees me get it out of the closet. She likes to have me put her in it backwards, so it can get challenging to get it zipped up because she is so excited. Shoulder straps could have better paddingShe likes being in this back pack, it was also very comfortable to wear. Easy to adjust, and nice little pocket for treats. She was about 7 lbs when I first started taking her out in it. During the process of vaccinations, I did not want to risk her getting I’ll. So I purchased this to expose her to the outside world. I wore it for park walks and bike rides she enjoyed it. The mesh and leg holes at the bottom are soft and comfortable, it did not irritate the sensitive skin on the inside of her legs. I also used it when I clipped and filed her nails it held her securely. She is now 5 months 10lbs, I might get a few more uses out of this. It’s great for puppies and smaller dogs.very convenientEverything about was exactly how I expected it. I’m going to be doing a lot more shopping, with getting stuff like this…She loves itGot this for my small dog. By the description of weight and size she should fit in it. But I could not find a good description of it. After fighting her to get her feet and tail in certain “pockets” over and over I finally gave up. She is 10 years old and this may be an option for a younger dogWas very small even though I order a larger! I will have to use for my smaller cat very disappointed! Have to try and find another one that will actually be accurate size!
