My son has been begging for a dog for the last 3 years. We finally got one. She's not a specially trained therapy dog, just a labrador retriever puppy. Since bringing her home, my son has forgotten to wash his hands. LOL, which is a good thing, because he is an excessive handwasher. My son is much less anxious and he's moving through the house on his own. Previously, he was too anxious to go from room to room unless someone was right there with him. He enjoys feeding the puppy and looking after her. He doesn't consider her scary or dirty. So far, so good
