I bought this because my dog is getting a little older and can’t handle long hikes like he used to. I used to carry him when he was tired, but when I saw this bag I knew I needed it! We have gone on several hikes and Smokey is always comfy in the pack. We even went bike riding with him in the pack. It works well for us. The only thing I would change is a cover flap over the inside of the zipper. I have already zipped his fur into the zipper by accident. (Poor guy!) Overall, I’m so happy with this pack and it’s worth every penny to be able to take my older dog with me on long hikes!
