This adorable Jack Russell is helping her best friend get on the move - by teaching her how to crawl. Simba, the 11-year-old pooch, can be seen showing 11-month-old baby Danni how to crawl by dragging herself along the floor. The footage shows Simba crawling along the floor in front of Danni, encouraging her to mimic her movements. And even when Danni tries to stop practising, Simba continually turns around to check up on her baby best friend.
