So far, so good! Dog loves the bed but my only concern is the sizing, I wish there were better sizing guidelines on the website. I followed the review recommendations and went up one size to the medium for my 11 lb poodle-bichon dog. Now, I am really wondering if the small size would have been better? My dog loves to curl up in the bumper so the smaller may have been better for her. I guess it depends on how your dog sleeps. If they like to stretch out when they sleep, the medium has plenty of room.
