Chewing is normal, destruction has a cause
Dogs chew to explore, to relieve stress and to burn off energy. Chewing releases calming chemicals in the dog's body, so it is a coping tool as well as a habit. When the target is your couch, though, something is off.
The most common causes in adult dogs are:
- Not enough outlet. The dog has energy and no job.
- Stress or anxiety, especially when left alone.
- Over-arousal: a keyed-up dog with nowhere to put it.
- Teething or dental pain, or a stomach issue, which a vet can check.
- A habit that got rewarded by accident, like a chewed item that earned you running in with attention.
Look at when and what. A dog who only destroys things when you leave may have separation distress. Read our separation anxiety page. A dog who chews while you are home is more likely bored or over-excited.
