Logan whines and yelps and runs in her sleep..chasing squirrels..no doubt about it! Sometimes she snores. It's too adorable! I never wake her up. She subconsciencely hears every sound anyway, so if I get up or walk by, she opens her eyes. When I get up in the middle of the night (she sleeps next to my side of the bed) she wags her tail and rolls over for a belly rub!!
