I bought two of these beds.  One for my ShihTzu (small) and one for my Westie (West Hightland terrier). They were slow in trying out the beds.  The Shih Tzu now sleeps in there at night instead of with my Mother.  He was always happy to go to in the bed, now he heads for his bed and reluctant to go with Mom, instead heads for his bed.  My Westie always sleeps with me.  Now she starts out in the bed and sometime during the night jumps off and goes in her bed.  They both appear to really like their new beds.  Highly recommend the beds
