Yep! They often do. Its funny, they project so much body heat being all curled up like that, that sometimes they gotta get up and move because the snow under them is melting LOL Funny thing is, he always has the option to go into a nice warm insulated doghouse that is packed with straw but he choose to snooze on the snow. If we bring the boys in, they just ask to go out agian soon anyways cause its too warm in the house LOL Ah well they know what they prefer...
