Yes the ADA did make changes to the law. It was minor, as you said it was about other species of animals. No, were are not required to show any ID under ADA. The city provides ours to help minimize the confusion. SOME places are taught to look for the gold cross tag he wears. Some times I grab a different harness and don't have it. They can't deny me access because I don't. If I remember correctly I thought CA was the only other state that actually offers a Service Dog tag?
