Alzheimer's assistance dogs must be alert 24/7 since their work task is to help their chief caregiver control wandering in the patient. Dogs have extraordinary hearing and are generous in using that hearing for the benefit of keeping an Alzheimer's patient safe. Should the patient decide to get out of bed no matter what the reason, as soon as their feet hit the floor, that could become a wandering situation. Like us, dogs can not ascertain what the patient has in mind but they can be attentive always listening for their sound. They will self-start the minute they hear the feet hit the floor and go and check the patient to be sure it really is a potential wandering situation. In order for the dog to be good at its job it must have good hearing and listening skills, it has to be attentive to all of the sounds around it and pick out the correct sound that it has been trained to identify--feet hitting the floor. Further, it has to have retrieving instincts as well since the dog will be retrieving the caregiver to the patient after alerting the caregiver to the problem. But it all starts with the dog's ears. The dog's ears must always be listening and the dog must be paying attention.
