Dogs nap frequently throughout the day. This is true of service dogs as well. Though they are service dogs, they are still dogs and have the same needs as any other dog. A large portion of a service dog's work involves down stays at the owner's side while the owner works at a desk, attends a movie, sits in a waiting room, or eats in a restaurant. This is boring work and service dogs often nap through it. Fortunately, dogs sleep very lightly and are able to quickly rouse themselves and spring into action when needed.
