My 9 month old started chewing on certain kinds of clothing i wear. She loves my jacket, and has chewed up a robe
But, for her it is more of a comfort thing. If u do not want her doing that then you ar egoing to have to be consistent about not letting her . Offer a chew toy, or Bulkly stick instead. Put her down every time she chews on your drawstrings. I just do not want her to swallow the drawstrings or plastic, that will be bad for her. If she is just a puppy then she does feel the need to chew.
