Usually a Service Dog is with their handler at all times (unless the dog is for a child, and then the dog is usually home with a stay-at-home parent), but there can be times when a dog has to be left home alone.
We have hesitated for a long time in posting the answer to this question because we don't want to encourage separating a people-oriented Service Dog from their handler or family. However, we recognize that circumstances do come up when a dog has to be left home alone (and sometimes, it might just be for an hour or two). In this case, we usually recommend leaving the dog in his/her crate with a new bone to chew on, and then the dog can then go eight hours without peeing.
