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!

Honestly the best pet purchase I have ever made. I have a small 7 pound very anxious dog with an amputated front limb and even with only one leg to use in the pack, he is secure, comfortable, and happy. He loves coming on bike rides and hikes. Also being up that high and near me has helped with his reactiveness toward other people and dogs. An incredible product.
