Why is my dog suddenly chewing things when left home alone?
The most common cause of chewing or destructive behavior when a dog is home alone is separation anxiety. Sometimes it can be triggered by a frightening event like a smoke alarm going off one day when the owner isn't home, a burglary, etc. - but sometimes it seems to start for no obvious reason. If you want to know for sure if this is the problem, you can videotape Cinder one day while you're gone - it's usually quite easy to differentiate anxiety from simple boredom or other causes of destructive chewing once you watch the tape.
If she is anxious, I would definitely recommend talking with your vet about this issue, since many dogs with separation anxiety need prescription anti-anxiety medication in order to improve - especially in the beginning. I would also suggest leaving her with a special long-lasting treat such as a Kong toy stuffed with peanut butter, every time you leave the house. This will help to keep her busy and encourage her to settle, and over time will help to reduce her anxiety by giving her something to look forward to when you leave. You could also try a DAP pheromone collar along with a natural calming supplement like Zylkene or Composure to see if this helps.
