Dog filmed pushing cart in Milpitas supermarket is a very good boy

Supermarket shoppers in Milpitas were treated to an unusual spectacle last week when they saw a German shepherd strutting the aisles on his hind legs, pushing a shopping cart as his owner browsed the store.

A video posted to Twitter of the dog rounding a corner past some refrigerators pushing a near-empty cart with his human in tow with the caption "I'm still shook" has amassed more than a half-million likes since it was posted Saturday.

The dog belongs to Isaac Hughes, a Milpitas resident who trains service dogs for work and taught his own pup some of the same tricks, Hughes told Inside Edition.

He said he rescued the 6-year-old shepherd, Cash, from a shelter where he was slated to be euthanized, because shelter employees found him aggressive and difficult to train, but the pup now knows scores of tricks.

Twitter users lamented how lazy their own dogs seemed compared to Cash. "Mine just lays down," one user posted, prompting an outpouring of pictures of sleepy dogs lying.
