Background [edit]. In 1985, the DoD called for an extensive review of the education and training functions. At the same time, President Reagan established the Packard Commission to review the management of the DoD.
Itâs recommended that four hours is the longest that dogs should routinely be left alone for. Every dog will be different, dependant on how old they are and what they are used to. For example, four hours would generally be too long for a very active, young puppy.
1 The average time owners leave their dog alone on a typical weekday varies by the age of the owner;. 44% of 18 to 24 year olds typically leave their dog for more than five hours, while just 13% of those aged 55 and over do. 2  Unsurprisingly, owners who work full time are most likely to leave their dog for longer.
