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.
I advise not to get a dog as it will be alone for a very long time and dogs being left alone can get very destructive if left alone to long. Occording to the RSPCA the maximum a dog can be left alone is 4 hours.o dog should be left alone for more than 4 hours on a regular basis and especially not a puppy! If you go ahead with this, can you either get home a lunchtime to take him out for a walk, or find somebody who can come in.
