Meeko is now almost 10 months and he has started doing something weird. It started with a new sweater I recieved at christmas and now he does it with everything. When he smells my new sweater  (recieved from a native american store) he pushes his nose right up to it and pulls away about 2 inches and his mouth opens and closes slowly but in steady movements. Like he is suckling but with nothing in his mouth. He now does it to things outside? Is it like one of those thing to help him smell…
