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.
The Morkie or Maltese/Yorkshire Terrier cross is a very human dependent breed of dog. They do not like being alone and can become destructive, depressed, bark and get anxiety if left alone for too long. Puppies should never be left alone in a crate longer then 2 - 3 hours at a time.
