We leave tomorrow morning for the vet clinic at Colorado State University in Fort Collins, CO. Miles is still pretty lethargic, so his regular vet told us take him to CSU, as he can't find what's wrong. Without more test equipment his best guess is a brain tumor, which is the last thing my girlfriend needed to hear.
Ruger (my Yorkie) is doing fine, and he will go back into the kennel for the trip. I think he had a good time there.
