Hello, I am the owner of a 10 month old female Wheaten Terrier. This has not happened until the past week or two, but recently she began to chew my mother's footwear. While we were not home (over the course of a week), she has managed to chew up 4 pairs of women's shoes, but has not touched anything that belongs to me or my father. I was wondering if anyone had a clue as to what could be happening that could be a cause for this strange behavior.
