Rehearse the reach
Use the clothing you normally wear on walks and place the pouch where you expect to carry it. Reach with the reward hand while the other holds a lead. Notice whether you have to look down, twist or reach across the dog. A belt, waist clip and cross-body strap each place the opening differently, so compare their position in movement rather than while standing in front of a mirror.
Try opening and closing the pouch one-handed. Check whether a drawcord, magnetic flap or hinged mouth stays where you expect it to be. Then bend as though picking up waste and sit as though taking a short break. An opening that is convenient to reach may also allow contents to spill. Follow the maker's closure instructions rather than overfilling the pouch to keep the mouth propped open.
Look inside before counting pockets
Check the internal corners, seams and liner attachment. Small crumbs can collect where a lining folds into the base. Ask whether the liner is removable and how each part is cleaned. If you use different rewards, consider a separate insert that the pouch is designed to accept, rather than mixing everything together and losing track of what remains.
Decide which other items truly belong beside food. Keys, used waste bags and a damp bowl need different storage. A separate outer pocket can be useful for a small essential, but make sure it does not bulge into the reward compartment or block the opening. Keep the main action simple: reach, select, deliver, close.
Match capacity to the session
Pack the amount appropriate for your planned activity and your dog's feeding plan. A large pouch need not be filled to capacity, and a smaller one may be easier to carry during a brief session. If you are unsure how rewards fit into your dog's food allowance, ask your veterinarian rather than treating pouch capacity as a serving guide.
At home, remove leftovers and clean the pouch according to its label. Let the liner dry before replacing it or closing the bag. Inspect the belt attachment, strap stitching and closure at the same time. Put the pouch in one consistent place ready for the next outing; finding a clean, empty pouch should not require checking every coat pocket.
