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.
Most dogs are right to be left alone for hours. It also just depends on the temprement of the dog, if it's a whinging dog & it crys the whole time you are gone well then you can't leave it alone but this is something you discover when you actually have the dogs. My dog is fine to be left alone for 8 hours while i'm at work.
