Josey occasionally will gently smack her lips and her tongue comes out a little. I have no idea how to search for this. She usually will do it several times before going to sleep, with me being more aware of it if she is up on my recliner with me. She seems perfectly healthy. I can tell when she is doing it as there is a little sound as her lips come apart. Could it just be a little comforting thing she does as she is falling asleep? I hope someone will know what I'm saying from this description and tell me it is just a doggy thing.
