Depression in dogs can be caused by a number of things, including major life changes

When something in a dog’s normal routine is altered or disrupted, mood problems can sometimes be the result. Major life changes are usually the culprit in dog depression.

Jones told INSIDER that the the death of an owner, periods in kennels, or a long stay in a rehoming center might trigger depression.

“Changes in the dog’s routine may lead to the dog being unsettled for a while. These might include a change in the owners’ working routine or new and quite different rules being put in place,” he added.
