I tried to attach the Puppy stroll bag" to. The Team K-9 harness and the 'Auroth tactical dog harness’ both are online. Both Worked in holding the kit on our puppy’s back, while our puppy was rolling on the ground, walking, and /or running. However, I prefer the Team K-9 harness.
To help secure the pack to the harness, I added Velcro strips across the lacing & / or the Velcro strips already on the harness. I leave the kit attached so we are ready to go whenever we have time to get out for a walk, I like feeling confident that we have the needed supplies to pick up any mess that may happen on our walk or anytime, we are out. Since our puppy loves to go on car rides.
