I’ve always loved the phrase a “dog-eared page”.
The OED defines it as “ having worn or battered corners” but we almost always use it to describe turning down the corner of a book page.
My own dog, Baffi, has the same ears, gently folded over like a corner of a page (or as a stranger remarked in the Metro one day, she has ears like artichoke leaves).
Baffi was a young dog when we lived in Paris. If the mail came when I wasn’t at home, it would be pushed under my front door, to be greeted by my bored little dog who, if it had some bulk, would nibble at its corners.
One such time, I opened the nibbled package and, to my delight, found that Baffi had gone through the packaging and made it to the book itself!
Of course, being 12 years old now, Baffi has matured into a non-book eating dog (she now conserves her energy for merciless killings of chipmunks in the garden), but whenever I look at the chewed corners, I think of how Baffi lead me back to the original “battered” meaning of “dog-eared pages”….
