Shelby has slept on our king size bed since 8 months. we crate trained her and she got to where she would wine, cry and jump on the crate walls all night long so one night i put her in bed with us and bam she has been quite all night every since. she does still need to go out 1 time most nights as she is just over 3 pounds so i think she just has a tiny bladder. There is nothing like waking up in the morning and having your "sunshine" kissing and snuggling you. it's the best way to start the day with a laugh
