Automatic dog treat dispenser – ideas

The client who has stiff hands takes her dog for walks when she is in her wheelchair and needs a method of automatically dispensing  a dog treat as the dog is trained to respond to treats when performing tasks. A large palm operated button is envisaged to operate the device attached to the wheelchair. Sketches of various schemes were prepared for the Southport Panel and are reproduced here for the interest of other panels.
