I'm actually in the last step of my dogs full certification. He was my therapy dog for the last 5 years. He is trained from our bonding since he was 3 months old to my needs. Days I cannot deal with people as well he breaks down that overwhelming sensation. Because our bond it makes it so I have to get up and around daily. Even if I do not go outside with him myself just the bit of fresh air or Sun can be a day changer for the good. The ada covers the basic laws and then you must stay to date with your local laws.
