Some dogs are trained to carry those carry sacks - like paniers on a motorbike or a donkey - particularly those dogs trained to work with disabled people. They are very useful and if you can stop them sliding round the dog, work very well. Most have a notice on them saying 'Guide dog' or 'Hearing dog' or whatever, just so people realise they are working dogs and not just a pet.

Reflective strips and velcro fastenings are great ideas, and the dog discourages people from stealing the things in the paniers.
