A family in Kensington, Pennsylvania, is asking for help after their 9-month-old Yorkie, Mahia, was stolen from outside their home in late December.

Mahia is a therapy dog for 4-year-old Dalex, who has autism and is mostly non-verbal. Surveillance footage shows someone grabbing the dog and leaving in a car. Since the theft, Dalex has been upset, frequently calling for Mahia and looking at her photos.
