Do you leave her kennel open all day for her to go in and out of on her own? That might help...she'll get used to it being her own little place and she'll enjoy being in there. My crew used to go into their kennels when I turned my cell phone on...they heard that little jingle and knew I was leaving the house so they all went to their 'rooms'...it was so cute
They also went in them for 'night-night' and for their meals...that way they knew what was expected of them and at what time...the rest of the day their doors were left open for them to come and go as they pleased and they would actually go in them for naps. Megan would go in hers and pull the door shut...she loved her room...but we also had to double check her lock because she could undo them and then she let everyone else out. Megan is quite a character!
