Greg has loved animals all of his life.  His childhood best friend was his dog, Tug, who was tragically killed by a hit-and-run driver. He loves to be around animals to this day.  Greg's foundation funded a scholarship named after Tug.  The foundation also has funded a variety of college scholarships for those who study humane animal care as well as marine science.  You can watch a fun You Tube video below, with a 25 second video featuring Greg's "triathlon training partner" Mojito learning to swim. You can also scroll through the slide show (below the video) to see of some of the other memorable 'friends' he has made from the animal kingdom.

Answer to commonly asked question:  Yes, this picture is real. It is not trick photography. Greg and a tiger really did get into a staring contest from about one foot away.  And yes, Greg blinked first :)
