service

why is it that there isn't some sort of state certification of service, companion animals where the animals must pass requirements in order to be around the public? Some one educate me if there is. I think there is so much more to a helper dog then just saying you trained your own or just putting a sign or something on them.  I put a lot more faith in an organization that raises, trains and test their animals to make sure they are appropriate to send out with their handlers. Just my opinion
