I will miss this goober. He has not been an easy pup to make comfortable here but he has proven to me once again what I often say, dogs that are anxious, nervous, or even aggressive do not want to be that way. Asking them to go back to what is more natural will always fee more comfortable than asking them to remain in an anxious state.
Frankie is not done. He will likely need some accommodations when he goes home and maybe for the foreseeable future but seeing his anxiety reduce definitely makes it worth it.
