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.
A dog should not be left alone for more than 12 hours, so if there are times when you are not able to get home to take care of your dog, boarding him may be a viable option. A dog boarding service will provide the dog with a place to sleep, play outside, run, and eat.
