I agree they're a decent winter option. To be brand neutral I'll suggest looking at Black Diamond, Golite, Kifaru, Oware and Ti Goat, for starters (there are others I'm forgetting). I have experience with Golite and Moss (r.i.p.) and will only caution that once you lower the sides to ground/snow level you'll need to concern yourself with ventilation, as moisture can build quickly. The center pole is always there to remind you you can knock down your shelter from the inside with a good thwack.
Sized large enough they're roomy and comfortable, and you can even dig a footwell if you're in snow. Anchored well they handle wind and precipitation. And there's no floor for the dog to rip up.
Worth a look.
