Lauri da Costa, a homeless man in Brazil who stumbled to the hospital after being hit in the face by a rock, has a priceless friend in his dog Seco. When da Costa went inside the hospital, neither he nor his dog could have known that it would be more than a week before he came out again.
Luckily, the injuries from the attack were not incredibly serious. However, during the exam, doctors discovered that he had melanoma, which required an operation right away. So, it was 8 days until da Costa emerged from the building for a reunion with Seco, who had waited outside in the parking lot the whole time. During their separation, members of the hospital staff fed Seco and gave him water.
Many dogs do wait for their guardians, although such behavior is not universal. Do you think your dog would wait for you?
