I think it would be a wonderful idea to have a service dog for your autistic son. It does sound like his issues might be better address with a dog that is trained to his disability. Is it your hope that he might some day be able to leave home and live independently? Is that a possibility? If there is even a slight chance that would make it even more important that the right dog be matched to your son. This is a very interesting thread and I hope that you keep us updated to what you are able to find out.
