found this one:) http://news.nationalgeographic.com/news/2003/04/0416_030416_seizuredogs.html - Essentially depends on both the dog and the owner (what the dog can do/learn and what the owner needs++ (and country and where they live and so on and so on... (if the dog needs to get help or just alert the owner for the possible seuzure++)). (hope that helps?... my googlefy is pretty decent...).. other than that:) http://servicedogcentral.org/content/faq/60 might be of help for anything else:)
