Ditto is wearing sunglasses and sweater at age nine. He weighs a scant four pounds. When Ditto was a puppy, his owner was housebound with a panic disorder. Her parents gave her Ditto as a companion, and he became a de facto therapy dog.

"He saved my life. By focusing my attention on him rather than myself I was eventually able to work through my panic disorder and step outside for the first time in over eight months. Since then he has been a constant source of laughs and love."
