Adorable dog is guilty of making a mess

Rigby is a 5 year old Chihuahua beagle mix that was rescued from a shelter. He has separation anxiety when we leave the house. When we come home, we usually find a mess in the bedroom from the garbage being tipped over and spread all over the floor. He never gets in trouble for it, we just pick it up and laugh at how guilty he acts every time! He always lays in his back and shakes his leg. In this video we were only gone for about an hour and my son went in bedroom to video the mess and his reaction. He's just so cute!!
