Some people might say that animals don’t feel the emotion of love and loss and that this dog was just sick, it’s not that he was crying.
If dogs have no notion of the past or long term memory and that they only live in the present, then why they enthusiastically welcome their owners back home after several months or even years.
However, the latest studies have revealed that dogs do have long term memory, they have a sense of identity and they can feel very intense emotions! Especially emotions of love and sadness! They can experience a very profound sense of loss too, like how the pooch named Wiley expresses his heartache on the grave of the person who cared about him.
There is no person in the world, even the coldest heart, who can watch this without tears.
