The dog's name is Capitan and that is not him in the first post made by the Boys it is the second one posted. Capitan has maintained a vigil by his master's grave for the last six years and it is absolutely true. I don't know the other dog pictured story but if you think all stories of pet loyalty such as that depicted here are fake, than I feel sorry for you and I mean that. I personally believe animals exhibit acts of amazing love and loyalty all the time and think that to be dismissive or pessimistic about animal loyalty and emotion is to somewhat disregard their capacity for learned behavior and intelligence. This is just my opinion so it doesn't make it right but the story is absolutely true.
Hope this helps,
