Luckily no one was injured. Probably stunned-I was!! We went to PA & set up in the dark at 7:30. My guess is hubby didn't secure the Velcro and bungee well enough. She's about 50 pounds and sleeps in our bed. I was sound asleep when at 1am my hubby says "the dog just fell out!" I ran out & got her. She seemed ok. Luckily he heard or she could have ran away. Just curious if anyone else had this happen? We are laughing now, better the dog than one of the kids. I'll make sure it's all secure from now on.
