Idk if this actually means anything, but my welsh springer licks her lips a lot. Right now she's chilling on my bed falling asleep, and licking her lips about every thirty seconds. She does this all the time. It reminds me of when I forget to put on chapstick and I have to lick mine. Could it be something similar?
She also licks/chews on her feet all the time. I don't know if the foot thing is her grooming, or if she's itchy, or what. I know she does it when she has prickles in her fur that she yanks out but she also does it when her feet seem clean. I've wondered sometimes if she had an itchy jaw, because sometimes it seems like she's rubbing that on her feet.
It doesn't seem like she is super agitated over any of this and it may just be she has weird habits, but I thought I may as well ask.
