Romeo loves his blanket

My dog loves his blanket so much that he nows has this uncanny ability to convert anything into a blanket.  


Why does he do this?  Well after reading a couple of blogs and reading a book, here is what I concluded.  Dogs are den animals and thus its their natural instinct to sleep or relax in small, covered space like a cave or a den.  Well Romeo has very few covered spaces at our home and no den - but a crate that he absolutely hates it.  That explained his love for his blanket and curtains.  

Next mystery for me is to know why is he sneaking out with socks!
