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.
All owners find it occasionally necessary to leave their puppydog at home alone. So before leaving your puppy for long periods, you should teach him how to amuse himself appropriately when left alone, such as by chewing stuffed chewtoys, and learning how to enjoy his own company without becoming anxious or stressed.
