If you signed up for a 1-hour hike, your hound’s paws will be on the trail for at least one hour.  Same goes for the time on other hikes.  The total amount of time your hound could be gone from home might be approximately 2 -3 hours; due to time spent during pick-up and drop-off, traveling to and from the hiking trails, time spent sprucing up for the ride home, and any other incidentals along the way.  So, adding at least 1-2 hours on to the hike time would be an average time.
