Incredible moment dog saves his friend's life

There are so many dogs that we as humans rely on every day.

Guide dogs who lead the poorly sighted and drug-sniffing dogs who man our airports are just two examples of why dogs are so amazing, but people always seem to have an even softer spot for heroic dogs.

Whether it's TV classics like 'Lassie' or heart-warming family films like 'Homeward Bound', the idea of dogs rescuing their human masters (or even complete strangers) captures our love and affection as few other things do. 

And as much as it's only natural to love hearing about dogs who save people, I think it's as heart warming and even more adorable when they save their friends.
