Cheryl Mazza’s support dog Jager is a constant help to his owner, and his latest trick has made the Scottish terrier more invaluable than ever before.

Mazza, of Kissimmee, Florida, suffers from multiple sclerosis and shares her and Jager’s exploits via dedicated Facebook and Twitter accounts.

On August 31, Jager showed off his newfound ability to collect the mail for his owner each day, with the pooch grabbing the latest deliveries from a postal worker at the end of Mazz’a driveway and bringing the mail back home in a perfectly sized bucket. Credit: Cheryl Mazza via Storyful
