Can Newfoundlands be left alone?

No, Newfoundlands cannot be left alone. They don’t like being left alone for more than a few hours at a time and if left alone for longer periods of time, they will get depressed and destructive.

If you leave your Newfoundland alone at home for a long time they will develop separation anxiety and start to chew things up around the house. You should look into a dog sitter or have a friend or family member stop by your house to provide mental stimulation and exercise while you’re at work.
