Jet and Jessica had been partnered for five years before the fateful day Jet saved Jacob's life. "I dread to think what might have happened if Jet hadn't been with us that day", says Jess.

Last September, when Jessica, Jet and Jacob were out for a walk, Jet suddenly pulled away from Jessica. She jumped up at Jacob's pushchair to propel Jacob to safety. The three of them had been just about to cross a road when a car collided with another vehicle just by them.
