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.
Well when a dog gets left alone for the day, he won't be too upset but if you keep doing that everyday, the anxiety builds up. Then if you go on a trip i would say that you need to have someone to come over and play with him for a while. About two days is a little long without anyone there. ShannonsBFF Â· 8 years ago.
