You all are so thoughtful in giving ideas. One of the good ideas that I am going to be following up on is training Nina to be a service dog. She would help him emotionally to be able to go on outings and spend more time in places since he is less anxious when she is there. You all are so sweet and caring.
PS. Since we adopted our first dog, Chris has started being more outgoing, having more eye contact and he is now very aware of us (his parents and brothers). Our dogs have been therapy for him. I can't say that dogs would work for every mentally disabled individual but it has been a miracle for our Chris.
THANK YOU!!!!!!!!!!
