Gordon isn't just a big dog - he's a massive dog. This nine stone Mastiff is all muscle and isn't scared of anyone!
A giant dog with a giant heart
But despite his rather imposing presence, Gordon has got a real soft spot for his two favourite people in the world - his little human sisters.
In fact, he always keeps a close eye on them and is only really happy when they are!
And a recent video posted by Gordon's dog mum shows just how much love he has for the pair.
Every morning, Gordon walks his sister's down to the school bus stop.
He takes up a position a few metres away, keeping watch over the young girls until the bus arrives.
Big Gordon then waits until they're safely on board before galloping back to the house with a very proud look on his face.
Job done, he seems to say! Now it's time for me to relax!
Gordon's dog-mum, Becky Lynn, told reporters that Gordon has been doing this ever since the girls started taking the school bus.
Gordon's adorable antics go viral
She shared the video on her Facebook page and was overwhelmed by the response. As well as receiving thousands of likes and comments, the story was picked up by news outlets across the world.
A condensed Youtube clip has almost 100k views, turning this gentle giant into a social media sensation.
Now check it out for yourself. But beware, this clip contains scenes of extreme cuteness!
