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.
You can end up with a dog that can never be left alone â ever! While my dogs are young (generally 2 years and under) I leave them crated whenever I am not home. I like to leave them with some projects to keep them busy, though I REALLY think they just sleep when Iâm not home.
