Sleeping IN the bed is greater than sleeping ON the bed.
This is Leila. Leila likes to burrow. So much so that one night we woke up at 2:30am to find her head floating amongst a sea of white… she ripped INTO a bed to sleep inside of it. She even created her own head hole so she could stay warm and still breathe. To this day we don’t know how we didn’t hear her doing this in the middle of the night. Clever, stealthy beagle.
