Very good quality

The quality of this bag is very good. I'm still struggling though with getting the dog into it, but when I do, she seems to be ok with it. We went on our first bike ride and she didn't fuss at all. I had a small issue with the bag at first and called support. They were quick to take care of it. The weather here hasn't been cooperative, but it's starting to warm up. We'll be taking lots more bike rides soon.

Love hiking with our dogs!

Have bought several of the K9 sport sacks for our dogs. We love them and the dogs do too! We really enjoy being outdoors with them, and the sport sacks allow us to hike longer and further distances. Highly recommend to pet lovers!
