After spending months deciding which Puprug/how many/what sizes to purchase, I finally dove in and ordered 2 of the small/medium size because I didn’t think my boys wanted to share. It turns out, it’s roomy enough that for whatever reason they have ended up always using only one. These are comfortable enough that I could probably nap on one if I wanted to lay with the dogs. The faux fur cover is soft, and they love nesting on it. For reference, one dog is 58 lbs and the other 68 and the size we got is still very roomy. We shall see about the durability but until then they Moses and Oliver approved-money well spent!
