I'm so glad to hear the thundershirt is helping, and I'm sorry I haven't drummed up more advice yet. I do hope that the links are giving some good ideas, though. She's lucky to have such good, patient people looking after her.

As per human thundershirts: I think this is one reason I like a snug-fitting sports bra. Sorry to hear the anxiety is prompting exploring the option, but I hope if you give it a whirl, it helps!
