Being alone and living alone is one of the saddest and most disappointing experiences for anyone. The same goes with the animals too.
They are very sensitive and being alone and living on their own could be traumatizing experience for their whole life, which will lead to other problems to.
This dog was living under the bridge in a container for most of his entire life. He had been alone most of the time and was afraid of people. When someone would approach him, he would run away and hide behind somewhere.
The dog was left there by the owners and lived a decade in misery and loneliness. Until one day, when a team of rescuers were passing by and noticed the dog heartbroken and lonely.
They immediately decided to take the dog to shelter, where the dog would be taken proper care of. It was one of the most important days in the life of the dog.
