My dogs are not trained or certified for anything, and I am an inexperienced dog owner, but having them has been life changing and I cannot imagine my life without their unconditional love. The benefits are amazing, and immeasurable. I feel safe in my home and when I go to sleep and wake up, and when I'm not doing well I have their companionship and love to soothe me. It's better than pills. I hope that you find a way to get an animal into your life. They are amazing.
