what do vets say these days about sedation?
the first time owen flew he was sedated. and i "practiced" once, at the vets suggestion. some dogs barf on sedatives. owen was fine. just kinda "mellow". it was about 10hours in transit. he never fully slept like the vet said he would, but just sorta stared. like i said earlier, he was a little hyper after, but didnt seem to have any lasting effects.

now the next question is, how big is boo? too big for carry on? (there's that whole thing im sure you know about cargo, pressure.... and minneapolis' rules about pets in winter, which im sure you've already checked out.... im assuming too much here, that you're returning there....) carry on vs cargo is a big diff.

good luck!
