Carry the essentials!
I love using fanny packs while on walks with my pup. I've gotten by with a pack designed for humans and used a headphone jack hole for poop bags. I didn't realize what I was missing until I got this dog-specific fanny pack. The material feels solid, and the pockets are all carefully designed with doggie needs in mind. There is a small pouch near the poop bag hole where you can stash the roll, a large interior storage space with a small pocket inside, an exterior pocket along the belly-side, and an exterior pocket in the front with a flap closure to keep treats fresh but also easy-to-access. I like the strong carabiner on the front, which I use to clip a water bottle to.
