I have two Medium Schnauzers. They do not like to share. I'm so glad I got each of them their own Chevron Gusset Couch Daydreamer Dog Bed. They love them. There's enough room for them to stretch out, roll over and they just love the raised sides. The size is perfect because sometimes they curl up into a ball while most of the time they are either rolling around on their backs, or stretched out enjoying the soft cushioned bottom. They have had beds similar to these in the past but they rarely last a week. These are sturdy, made very well and seem to work well for them. I got the large and found that it's perfect. I received them sooner than scheduled which was great so I decided not to make them wait until Christmas. They love these beds and so do I. Thanks Wayfair for another great product.
