Dogs are among the most loyal animals on the planet. They will truly love their family with no limitations and would do absolutely anything for them. We often hear sad stories of how an owner has to leave their dog and how the dog never truly gets over the loss.
Capitan is an example of undying loyalty. His owner who passed away over six years was buried at a nearby graveyard. Capitan still visits his old owners grave as much as he can, before returning back home with his new family.
