I've caught Olive a few times in the last couple of days biting one of her nails on her left front paw. It sounds like she's chewing on something she shouldn't from the other room; it's quite loud. She isn't limping or favoring it at all, and a visual examination reveals nothing. I looked in her mouth too, and there doesn't appear to be anything other than dog breath going on in there. She has plenty of toys to chew on, though nothing hard because she destroys them in a matter of minutes. She'll be two in November. Has anyone else experienced this with their corgi? Thanks :-)
