[matese]

Welcome to YT. Can she be blocked off from this area. If she can't get to that door, she can't guard it. I would find a way of keeping her totally away from the door. Throwing anything over this baby will only scare her and may provoke attack mode. Even tho she knows you, she is missing her momma. First her momma disappears, she is transported to your mother, then taken from there to your home. She is scared and confused. Do not even "think' about calming tablets, this is not your dog, you don't know how she will react to something like that, or if her digestive system can handle it. You have to eliminate the problem by finding a way of keeping her away from that door by blocking it off, keep her in another room and block the doorway. You cannot crate a dog that is not use to crating. Sorry you are off to a rough start with this baby, but you need to understand she is scared, confused and she's a senior which adds more stress to her momma disappearing on her.
