Dog grits her teeth along people's clothes
Wanted to try to find an explanation for a habit that our nine month lab/collie mix is doing...
It's hard to explain, but she grits her teeth and tries to nibble on your pants or your shirt or arm, she doesn't bite or actually nibble on your clothes, only on the very top layer. She doesn't harm fabric, people or anything, but you can hear her teeth go a mile a minute and it tickles. It's kind of like she is eating corn on the cob but just going through the motions and not touching the corn at all.
Was just curious if anyone had ever experienced this type of behavior before with their dog. Is it a nervous habit? She's a very happy dog.
Thanks in advance for any insight anyone can provide.;) :)
