Oh man! I was vacuuming and she was doing her barking at the vacuum and trying to save me from that nasty loud machine. I told her it was okay (which usually calms her down) and she backed up. I lifted the cord so I wouldn't vacuum over it and it must have come right to Collins mouth height because I look over and its in her mouth and she's chewing on it.
Thank god a quick "Collins no!!" made her drop it but oh dear lord. She has never been a cord chewer so I'm hoping this was a one time thing. I don't need another scare like that!
