We must begin and end all commands we teach our dogs, otherwise there is almost no value in the command itself. The clicker not only marks, but it ENDS the behavior. I always make sure my students know the clicker is not forever. After we teach the dog that the release is part of the command with the clicker, we can then start to make the transition to using a release word instead. Then, I like to teach the dog that the release is actually a reward in itself. I will teach a release that lets them satisfy their prey drive and pair it with a specific word or phrase that is just meant for the dog. With repetition, we build the association of the release word with the reward, and voila, we have a dog who wants to wait for it, therefore holding the command. Varying the length of time between some quick releases and working up to more challenging ones will teach your dog that the time they hold it may change, but the sequence does not: we give the command, they obey, we release, we reward. By teaching them from the start that they need to wait for us to release them, we can then hold them accountable.
