This pooch has quite a sense of humor. 

Dustin, a Jack Russell-pug mix, has Twitter in stitches over a video that shows him mocking his corgi friend’s walk. 

The clip shows Dustin and his pal Tayto, from Sydney, Australia, walking side-by-side down a hallway -- only Dustin appears to be mimicking Tayto’s walk by crawling beside him, instead of walking on his paws.
