Oh, well you’ve got a good one then. That’s a sign of bonding to ‘their pack’. Licking and chewing on clothes is what they do when they’re young and/or insecure. Just wear old clothes and go with it to build a strong and secure bond with her. She’ll grow out of it as she settles in and becomes comfortable. She will grow up associating with people more than dogs which is typical of many labs.
Thanks for that input, very reassuring. Right on target about the old clothes!!
