[yorkie mad]

ive had Olly for 7mths now , hes 19 mths old (rehome) anyway he has some strange ways. He will burrow under pillows, covers any clothing lying around and even at the moment he has burrowed his way under my dressing gown as Im wearing it lol. He just seems to like his head buried under something. My worry is that when he joins me in bed for a lie in he will burrow under the duvet and work his way to my feet and Im concerned wether he will be able to breath properly especially if I fall asleep. Has anyone had this weird experience or is my Olly a little nutter lol
