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.
How long to leave dog without pottying. We are new to the dog thing. Our dog is 1 year old and he can go from 8 at night to 10am sometimes without demanding to be let out. We are going on vacation, and can have my nephew stay with him, but he has to work the majority of days where he would be out of the house for 9 hours.
