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.
Best Answer: Pretty much any breed of dog can be left alone for a few hours - there are a few people focused dogs which would not do as well but should be ok even for a couple of hours. I work full time and have managed to raise 2 giant breeds from 10 weeks without any issues at all so you do not need to be around all the time for puppies.
