If you are training a dog or just working on obedience and good contact with your pet while walking, then you will need small pieces of “takeaway” goodies that you can take with you to encourage your pet’s good behavior during the walk. The size of a piece of such a training treat should be about 1x1 or 2x2 cm for a medium-sized dog - so the pet will feel that he was treated, but will not switch to feeding.
