Studies have shown that dog kennels are considered an overstimulating environment which can result in a negative welfare state. This study investigated the effects of implementing a quiet-hour during the day on the activity levels of 12 working dogs. Dogs had accelerometers placed on their collars and activity levels were recorded continuously for three weeks. After the first three weeks, a quiet-hour was implemented from 12-1pm each day (Monday-Friday) and data was continuously recorded for another three weeks. The implementation of a quiet-hour reduced not only overall activity levels, but also activity levels at night when the dogs were not in the kennel as well as during the days the dogs were not in the kennel (weekends and holidays). Quiet- hour is an easily implemented method that has the potential to improve welfare of not only working dogs, but other dogs in a kennel environment. Further studies are required to explore the extent of how a quiet-hour could improve sleep patterns and the performance of working dogs.
