My borderterrier loves this thing. Its light and seems to give out alot of heat. I've previously just brought a little blanket for my dg to sleap on but I can really tell that she likes this thing much better. Also, it dries quickly after having been soaked. It does smell a little I think, but everything else smells too in a tent after a few days on the road so this is probably not a big problem. Maybe its not ideal for really tiny dogs that might just be better off sleeping by your feet on a blanket thats easier to fit in the tent.
