Does anyone have a dog that randomly licks for no apparent reason? Adam does this and Ive always wondered if it means anything health wise. He will be sitting comfortably and then just start licking his lips and the air with his head stuck out. You can interrupt him for a second but then he has to keep licking and he does it for a minute or so at a time. Ive checked Youtube and it def isnt fly biting. The closest is a clip of a JRT called 'OCD licking'. Does it sound like I should be worried or is it just a strange quirk??
