I just wanted to mention that while they *can* ask for certification ID, and I agree that most of us would be glad to provide it, this can hurt those guests who trained their own SD's by setting up a precedent for CM's to think it's required when it isn't. Some people train their own SD's because there are long waiting lists for legitimate training programs, others do it because they would like to raise the dog from puppyhood or perhaps they have other dogs in their households, and this is not allowed by several programs ( the SD must be the only dog). Some programs charge a fee which is expensive, and agencies that certify OTSD's ( owner-trained service dogs) always charge a fee which many cannot afford. Disney is in a real bind, as are other places of business. They don't want to offend a guest or challenge a guest, legally they can't ask for proof, and there are many invisible disabilities for which a trained SD could mitigate the disability. More and more people are using medical alert dogs, hearing dogs and autism dogs, for instance. Long gone are the days when the only SD's you'd see were German Shepherds guiding the visually impaired. So if they can't tell *why* someone has a dog by looking at the guest and seeing an obvious disability, then it gets touchy to ask someone those three allowable questions. I understand this difficulty, but still, they *need* to get comfortable asking those allowable questions, and comfortable in challenging a questionable situation, or asking a guest with a disruptive, ill-behaved dog to remove that dog from their parks and resorts.---Kathy and Skye
