Can your dog tell you're going into labor?

Emilie
My baby was due on Sunday, the 22nd. And every night since then my husband's dog has been acting a little funny towards me. She doesn't leave me alone, follows me into the bathroom and leaves when I leave, she sleeps by my bedside, and has been staring at me with full attention. This is the first time she's acted this way. She's definitely more my hubby's dog than mine, so I'm just wondering if she's sensing something that I'm not haha. What do you ladies think? Anyone experience anything similar?
