Lucy is a spaniel. Petting and rough-housing with Lucy is fun, because she is fluffy.
We rough-house on a regular basis, and afterwards, she always drags the side of her face along the carpet. She also does it on the carpeting in my mom's room when she gets home from work. She is energetic and her tail is always wagging when she does this, so I assume it's a good thing. Still, does anyone know why dogs do it? Is she scent-marking? Is she scratching an itch? It's funny when she does it, I'd like to know why.
