Thanks so much, Pennymom! It was interesting to see the note that greyhounds might need more, not less, of a dose. I told Wife, and gave her the URL. Shane got the methadone before we had a chance to object. He is in a pen where lots of staff are able to watch him. He has pillows. The other dogs in the room are being good. The internist has been consulted. We think he's in good hands. Now we just have to do the spiritual part.
