What are the shenanigans you are aware of with service dogs? Badly behaved dogs, or just people that lie about why they need a dog? My suggested plan would make such lying unnecessary since all you need to do is prove the dog can pass a behavior test, it has nothing to do with whether you supposedly need the emotional support animal. (and of course, this doesn't give anyone the right to bring the dog in a store or in a plane or whatever, unless the business wants to allow it)
