Hello Yorkie community. Have 2 adults who had their first litter 2 months ago. The Mama dog never ate or chewed on parts of the house. She did like sticks. (Would steal kindling from the fireplace) The Poppa dog picked a corner molding in the living room to chew on. He also likes straw baskets. Now the 2 month old pups are refinishing my daughters dresser and bedside table. Do they have a dietary fetish? Need a supplement? Thanks for any help.
