A TINY horse who suffers from a rare form of dwarfism has become an Internet superstar after his owner posted a video to Facebook.

Little Shammy’s condition may make him smaller than his fellow equines – but that doesn’t stop him being mischievous and delighting his online fan base.

After Michele posted a video to a Facebook page she set up for Shammy, he quickly gained 5,000 fans so she decided to write a book about his exploits.
