I thought at first he was rubbing the top knot out, so i removed it and still continued to do this. Then i thougth it was because he was also teething, to relieve some pain and rub his gums

So his eyes are wet, face is wet and i still keep trying to figure this one out

Maybe it's a phase, he does do this in the morning too like another post said and it leads into a full body rub into the carpet...IDK, just a puppy thing i hope, he does this after being out in the mornings with his feet, face in my sofa

Just gotta laugh if off
