Pugs can get comfortable anywhere.
Even though Sid has half a dozen beds of his own, a padded fleece carpet, and access to my couch and bed, I still frequently catch him lounging in bizarre places and/or positions. I think it’s just a weird pug thing.
Although, to his credit, the little guy may have actually been doing some post-walk stretches. With the piles of snow and slush our daily walks have turned into more of an adventure than usual.
