My little Yorkie didn't know what to think of it at first. He was curious as to why his old raggedy bed was gone and this fluffy new bed was here. After we put his blanket and a few toys on it and got his scent on it he absolutely loves it. The smallest size was perfect for him. Even that was still big for him but he tucks into the side, curls up and nods off no problem. Half the time you can't really tell he's in there because the bed is dark color and he is too. But overall it's perfect, he likes it and that was my biggest concern was that he wouldn't because he's a little picky at times. But he's all about it now. Nice and fluffy and he curls right up in it and is good to go.
