Nice dogs Shaneo
I dunno where Sean is but he has two mastiff a bit like your girl on the right - tho it's hard to imagine either of them being anxious about anything.
Bizarre how some of the big dogs get it. Was just remembering my friend's great dane from way back when - their house got burgled - guess where they found the dog...
Under a child's bed.
Don't know how it fitted under there but it was always very shy.
I think if you cover the sides of the crate with a sheet or blanky your anxious dog will love it.
