I think you need to determine what you want from this dog before you decide what kind. Is this dog going to be a service dog or a companion. I know a service dog can also be a companion, but it does not always go the other way. Also, service dogs do need extra training and usually have to go thru testing, I believe. The training is a lot of work, as it usually requires extensive socialization in a variety of situations so that the dog is calm in new places and aroudn new people. Obviously you want a dog that is loyal to your daughter, but if it is a service dog that will attend public appointments and such with her, it has to allow peopel to do their job. I would contact the canine companion site that someone posted to get further information. Also, if your daughter is working with OT or PT, I would talk with them also.
