Hi Jennifer.
First, it must be said, Zoe is adorable...I know she is grown up now from that picture, but I bet she is still beautiful!
I have heard tons about Rescue Remedy...it is worth a shot. Also, and this will sound weird, but try wrapping a t-shirt tight around her body. Put a t-shirt on her and pull it tight and pin it. I don't know what the deal is, but have heard it works perfectly!
It is so disturbing to see our babies so stressed. My Jack has just recently starting showing anxiety with wind. I know, crazy. We had some pretty windy days a couple weeks ago which caused some inside doors to slam and the curtains to blow in the windows....it took me a few hours to figure out what he was upset about (I thought maybe he wasn't feeling well). Ever since, when the windows are open and the curtains blow in....he gets really clingy. I am hoping this phase passes.
One thing to keep in mind (and this is hard) is don't cuddle her or try to soothe her with hugs when she is having anxiety symptoms. That is the first thing we want to do, but you could actually reinforce her anxiety (she likes affection and affection is a positive reinforcer, so when you give her affection when she is anxious, in dog speak, you are 'rewarding' her for her anxiety.
I wish you luck with Zoe. Hopefully you have success with the rescue remedy or the t-shirt!
