Simple pedestal training
If you have tried pedestal training and been unable to capture the behaviour you are looking for e.g. your dog standing on the pedestal, try placing a flat item on the floor such as a table mat. Stand fairly close to it and your dog will probably come over to investigate. The moment a paw touches the mat - click and treat. Repeat and do lots of short fun sessions. Before long your dog will immediately come over and stand on the mat. You can then try placing the mat on the pedestal.
