Three-Legged Therapy Dog Retires

A special collie is retiring, but not before a big goodbye party.

Katie had to have her back leg amputated after being severely neglected.

The Scholl Center for Communication Disorders adopted Katie from a rescue organization two years ago.

Since then, Katie's been hard at work, soothing crying kids and nervous adults.

Friday, patients and staff thanked Katie for her calming presence.

Katie is 13 years old.
