Puppy Emotional Support

Many therapists at Chicago DBT Institute have dogs who hang out all day in their offices. They love making friends and are all very lovable and sweet. We find the pups help most people feel comfortable and supported, providing a little affection and a warm-hearted welcome. If for any reason you do not want to share your therapy session with a dog, we will be very happy to give them a time out in another office. We want you to feel comfortable and at home!

If your compassion does not include yourself, it is incomplete.
