Destroying Furniture

Polly, the little rascal, is chewing on the furniture. She is not just chewing on the living room table, which has already been chewed upon by earlier generations of Shiba Inus, but on the sofas and on Paula's and Daniel's big bed. This is not how I have raised her. Mum and Dad claim this must be traits brought to Polly by her father, they say neither of them have dogs who chew on furniture in their pedigrees. Polly's father does not chew on furniture, but maybe he did when he was a pup himself. He has not told me either way. I hope she will grow out of it soon.
