Lethargy and Depression

If you’ve ever witnessed a dog in the throes of separation anxiety, you may notice behaviors that are similar in your dog after his companion's death or in the midst of an extended absence. Some common behaviors include running from room to room as though searching for someone and following you constantly as though fearful he will lose sight of you. Some dogs may appear nervous and anxious, while others will withdraw and act as though they want to be alone.
