My Bailey is 4 nearly and hasn't chewed since she was 18 months but out of the blue over Christmas she went into the cupboard and stole my new shoes
she chewed the heal so I got a black marker pen to fill in the chew marks so I could wear them New Years Eve. Wish I hadn't bothered as the shoe got caught in my Per una skirt ( the heal was just to rough) and caught the lace on the base of skirt.
My other cocker is 18 months and she still chews if left
she has loads of toys kongs and I play hide and seek with the food when she's left.
My other 2 have never chewed a thing
Good luck I know how annoying it is and expensive
